Abstract:
Based on analysis of submerged arc welding arc heat source model and droplet heat inputting uniform distribution, ANSYS parametric design language was applied to develop sub-program for loading moving heat sources. ANSYS software was used to calculate the temperature fields. In the same welding conditions, weld seam width and depth value of experiments and simulation are contrasted, the biggest error was below 5%. The influence of different welding speed to molten pool temperature of twin-arc submerged arc welding was analyzed, it obtained results that temperature field distribution of twin-arc submerged arc welding changes more gentle than single arc submerged arc welding in condition of increased welding speed, it was helpful to the further analysis of molten pool dynamic behavior and weld seam shape factors of twin-arc high speed submerged arc welding.

Abstract:
Introduction. The weld formation under the submerged-arc welding of bridge metal structures is investigated. The work objective is to study possibilities to increase the welding performance during the arc welding of fillet seams. Materials and Methods. Methods of computer analysis are used to optimize the technology. With their help, a physicomathematical model of fillet weld formation under the submerged-arc welding has been developed. It is based on a system of equations for thermal conductivity and equilibrium of the weld pool surface. In this system, the formation of an arc cavern is determined through the flux boiling isotherm under the action of the arc column radiation; heat transfer by the flux vapor inside the arc cavern and the influence of the spatial position on the formation of the weld pool are taken into account. Results. New mathematical relationships that describe physical phenomena under the submerged-arc welding of fillet welds are proposed. The key feature of the proposed model is in the fundamental difference between the submerged-arc welding and the gas-shielded arc welding, i.e., during submerged-arc welding, the arc burns in a gas-vapor cavern that appears due to the melting and evaporation of flux. Numerical simulation of the temperature distribution during production of the fillet welds in 1F and 2F positions is carried out. The process constraints under the single-run welding of the fillet welds are specified. It was determined that the single-run submerged-arc welding of fillet welds in 1F position exhibits high-quality formation of welds for almost the entire range of metal sheet thicknesses. During production of fillet welds in 2F position, high-quality formation is provided only for sheet thicknesses up to 8 mm. At heavy thicknesses, the formation of the seam is disrupted due to the melt flow from the vertical wall. In this case, the leg length decreases; a typical undercut is formed; so the weld will be asymmetric and less strong.Discussion and Conclusions. Comparison of the numerical analysis results with actual data on welding modes under the production of bridge metal structures shows that the existing fillet welding technologies have already reached their maximum efficiency rate. Further productivity gain is possible by forming oversized legs only with multiarc or multielectrode welding methods.

Abstract:
The article dedicated "Submerged arc welding and meltıng technology" method, which is one of the technologies for repairing friction-worn parts of oil and gas equipment. The efficiency, technological regime,advantages of the process are noted, and it is also shown that this method is used today in the oil industry and shipbuilding. With these methods, the repairing of a part of the pieces corroded by friction, as well as the possibility of welding steel plates of different grades and thicknesses, was reflected. In determining welding procedures for certain applications, the welding engineer must first take into account the specific welding qualities required, since in practice, although some factors can be determined quite accurately, others change during manufacturing process. Arc voltage, electrode selection, welding speed are important considerations in determining operating mode, and the penetration caused by high voltage combined with low speed is indicated accordingly. The supply of agent (glycerin) to the recently created attachment zone is indicated. It reduces the thermal impact of the cooling arc on the half and will increase the cooling rate of the deposited and metal, decreasing the deformation and self-heating of the adjacent elements of the half. Besides, the liquid serves to safeguard the liquid metal from the harmful effects of chemical element and gas. Keywords: overheating, vibration, crack, arc voltage, welding defects, welding speed, technical glycerin, soda ash.

Abstract:
Submerged Arc Welding process (SAW) is a high quality, very high deposition rate welding process. It has lot of social and economical implecations.This paper makes an attempt to uncover an important area on studies of temperature distribution during submerged arc welding because this may pave the way for application of microstructure modeling, thermal stress analysis, residual stress/distribution and welding process simulation. Prediction of temperature variation of entire plates during welding through an analytical solution is derived from the transient multi dimensional heat conduction of semi infinite plate. The heat input that is applied on the plate is exactly same amount of heat lost for electric arc, which is assumed to be a moving double conical heat source with Gaussian distribution for Submerged Arc Welding process. Good agreement between predicted and experimental results has been achieved.

Abstract:
The task of designing concepts for the next generation of submerged arc welding heads was given by ESAB. ESAB is a global company manufacturing welding equipment for a wide span of industries and uses. In October 2011, ESAB introduced a new technology called Integrated Cold Electrode™, abbreviated and trademarked as ICE™. ICE™ is a technique which utilizes three electrodes in a highly productive and stable process. The current state of the ICE™ technique focuses on welding thick plates with conventional joint types such as x- and v-joints. The next phase in the development of the technique is to be able to weld milled 16/8°-joints which are developed by German company Graebner. This kind of joint determines the requirements of the next generation of ESAB’s equipment for submerged arc welding.Simultaneously as designing the welding torch being able to weld the 16/8°-joint, a concept for a highly customizable modular head was developed enabling the possibility to tailor the submerged arc welding process according to the customer’s precise needs.A progressive conceptual development has been conducted in close collaboration with ESAB. Theoretical models have been developed to evaluate thermal-electric behavior of the welding torches to obtain plausible dimensions for the electric conductors to withstand the effects caused by joule heating. Deliverables for the project has been well defined 3D CAD-models while a prototype was not included in the scope of the project.One concept for the 16/8° joint is presented as the Narrow Joint Concept, NJC, which fulfills the requirements specified. The NJC is developed with focus on smart design with low manufacturing cost as well as ease-of-use for the operator. NJC brings ICE™ into narrow joints.The Modular Head Concept, MHC, presents an idea how to create a fully customizable process with the possibility to emulate the ICE™ technique
Uppdraget att utveckla nästa generation pulverbågsutrustning gavs av företaget ESAB. ESAB är ett globalt företag som tillverkar svetsutrustning för ett brett spann av branscher och användningsområden. I oktober 2011 lanserade ESAB en ny teknik vid namn Integrated Cold Electrode™, ICE™. ICE™ är en teknik som utnyttjar tre stycken elektroder i en högproduktiv och stabil svetsprocess. I dagsläget fokuserar ICE™-tekniken på att svetsa konventionella fogtyper såsom x- och v-fogar i tjocka plåtar. Nästa fas i utvecklingen av tekniken är möjligheten att svetsa frästa 16/8°-fogar som det tyska företaget Graebner utvecklar. Denna typ av foggeometri ger kraven för ESAB’s nästa generation pulverbågsutrustning.Simultant togs koncept fram för att möjliggöra skräddarsydd utrustning efter kunders specifika processbehov.En progressiv konceptutveckling har utförts i nära sammarbete med ESAB. Teoretiska modeller har tagits fram för att utvärdera de termo-elektriska egenskaperna hos de utvecklade svetshuvudena så att dessa kan motstå den resistiva uppvärmningen som sker i de elektriska ledarna. Då en prototypframtagning ej låg inom ramen för arbetet har detaljerade 3D CAD-modeller producerats.Konceptet för 16/8°-fogen kallas Narrow Joint Concept, NJC, och uppfyller de uppställda kraven. NJC är framtaget med fokus på smart konstruktion där låg tillverkningskostnad och enkel användning har premierats. NJC sammanfogar ICE™ och smala fogar.Det modulära konceptet kallat Modular Head Concept, MHC, representerar en idé för att skapa skräddarsydda lösningar efter kunders behov. MHC äger förmågan att fungera som ett ICE™-huvud.

Full text
Abstract:
The study emphasizes the effects of multi-pass narrow gap (NG) Submerged-Arc welding (SAW) on the Heat Affected Zone (HAZ). The differences between the HAZ of single-pass welds and multi-pass welds are radical and are caused by the subsequent thermal cycles which only exist in multi-pass welding.
A series of experiments were carried out to establish the relationship between the welding thermal cycles and the mechanical and microstructural properties of a HAZ. Both real and Gleeble simulated HAZ's were investigated.
Theoretical and experimental analyses indicate that the HAZ's in multi-pass welds can be improved significantly by the welding process itself. However, multi-pass welding does not always improve its HAZ. To realize the improvement, some special criteria must be met. The most important parameters are heat input, welding speed, deposit thickness and inter-pass temperature. This study establishes the relations between these parameters and the effects of HAZ refinement. There are some domains of the parameters in which HAZ refinement can be realized. The research reveals that in multi-pass NG welding, a set of welding parameters can always be found to fulfill the conditions for HAZ improvement.
Real welding processes, with welding parameters optimized according to the analyses, were performed and a totally refined HAZ was achieved under laboratory conditions. It is suggested that the method can be applied to in situ welding situations.
High heat input does not necessarily lead to inferior microstructural and mechanical properties in multi-pass NG welding. As long as the conditions for HAZ refinement are satisfied, an improved HAZ will be obtained no matter how high the heat input is. This also leads to the conclusion that the HAZ in multi-pass NG welding is less sensitive to heat input than that in single pass welding.
The tempering parameter, which has been used to evaluate the tempering effects at constant temperature, is successfully introduced into welding (non-isothermal) conditions. The effects of precipitates in 2.25Cr-1Mo steel are theoretically investigated.

Abstract:
Automated fusion welding processes play a fundamental role in modern manufacturing industries. The proliferation of joint geometries together with the large permutation of associated process variable configurations has given rise to research into complex system modelling and control strategies. Many of these techniques have involved monitoring of not only the electrical characteristics of the process but visual and acoustic information. Acoustic information derived from certain welding processes is well documented as it is an established fact that skilled manual welders utilise such information as an aid to creating an optimum weld. The experimental investigation presented in this thesis is dedicated to the feasibility of monitoring airborne acoustic emissions of Submerged Arc Welding (SAW) for diagnostic and real time control purposes. The experimental method adopted for this research takes a cybernetic approach to data processing and interpretation in an attempt to replicate the robustness of human biological functions. A custom designed audio hardware system was used to analyse signals obtained from bead on mild steel plate fusion welds. Time and frequency domains were used in an attempt to establish salient characteristics or identify the signatures associated with changes of the process variables. The featured parameters were voltage / current and weld travel speed, due to their ease of validation. However, consideration has also been given to weld defect prediction due to process instabilities. As the data proved to be highly correlated and erratic when subjected to off line statistical analysis, extensive investigation was given to the application of artificial neural networks to signal processing and real time control scenarios. As a consequence, a dedicated neural based software system was developed, utilising supervised and unsupervised neural techniques to monitor the process. The research was aimed at proving the feasibility of monitoring the electrical process parameters and stability of the welding process in real time. It was shown to be possible, by the exploitation of artificial neural networks, to generate a number of monitoring parameters indicative of the welding process state. The limitations of the present neural method and proposed developments are discussed, together with an overview of applied neural network technology and its impact on artificial intelligence and robotic control. Further developments are considered together with recommendations for future areas of research.

Abstract:
Este trabalho apresenta uma análise das condições de soldagem sobre o desgaste abrasivo de um revestimento duro. O revestimento foi feito pela deposição metálica por arco submerso variando os parâmetros de soldagem e utilizando fluxos comerciais. Foram utilizados dois conjuntos de parâmetros de soldagem (conjunto 01 com velocidade de soldagem de 55 cm/min, extensão do eletrodo de 35,0 mm, tensão de 30V, corrente de 450A e o conjunto 02 com velocidade de soldagem de 50 cm/min, extensão do eletrodo de 25,5 mm, tensão do arco de 26V e corrente de 440A) e quatro fluxos comerciais (identificados como E, M, L e R) formando assim oito condições de soldagem. Foram feitas duas camadas com três cordões de solda cada sobre uma chapa base de aço SAE 1020. Corrente contínua com polaridade direta (CC-) foi utilizada em ambas condições. A resistência ao desgaste abrasivo a baixa-tensão foi avaliada pelo ensaio de desgaste do tipo Roda de borracha/areia seca conforme a norma ASTM G65-94. A análise microestrutural foi feita por microscopia óptica e a análise da região desgastada por microscopia eletrônica de varredura. A resistência ao desgaste abrasivo dos revestimentos do conjunto 01 foi superior em comparação com os revestimentos do conjunto 02, para todos os fluxos utilizados. Os fluxos E e R proporcionaram os melhores desempenho e a martensita de agulhas foi a microestrutura com a qual foram obtidos os melhores resultados de desgaste abrasivo a baixa-tensão neste estudo realizado.
This work presents an analysis of the welding conditions and its effects in the abrasive wear of hardfacings. The hardfacings were obtained by submerged arc surfacing. The welding variables were changed and the commercials fluxes were used. Two groups of welding variables were used (group 01: a traveI speed of 55 cm/min, an electrode extension of 35,0 mm, a voltage of 30V and an amperage of 450A; group 02: a traveI speed of 50 cm/min, an electrode extension of 25,0 mm, a voltage of 26V and an amperage of 440A) and four commercials fluxes (E, M, L e R designated) establishing eight welding conditions. Double-Iayered ot three beads were deposited (applied) on a SAE 1020 base metal plate. Direct current electrode negative polarity (CC-) were used in both groups of welding. The low stress abrasion resistance evaluation was carried out by dry sand/rubber wheel apparatus according to the ASTM G65-94. The microstructural analysis were done by optical microscopy and the worn surface analysis were done by scanning electronic microscopy. The abrasion resistance of the group 01 was superior as compared to the group 02, independent of the fluxe was used. The fluxes E and R presented the best results and the befter abrasion resistant microstructure was lath martensite.

Abstract:
Current requirements for high strength pipelines are placing extreme demands on welding consumables. These applications include strain based pipelines using X80 as well as traditionally designed pipelines using X100 and even X120 base materials. Traditional procedures used in the pipemills for both the seam weld and the jointer weld utilize a SAW process with very high dilution and high heat inputs. Existing consumables are not able to meet the minimum strength requirements under these conditions. A project was undertaken to develop an alloy system that could meet these requirements while still allowing the use of traditional welding processes. Testing results with this new consumable are presented and future work is described. This alloy system may also prove useful in other high dilution applications where high strength is required.

Abstract:
Many pipe mills may not be familiar with a Crack Tip Opening Displacement (CTOD) requirement on the pipe seam weld, nor will they find easily relevant information in open literature. Influencing — and certainly not independent — factors are: welding parameters, base material and consumable selection. Out of these, the welding parameters such as heat input and cooling rate cannot be varied over a wide range during the pipe production, which means that the leverage is rather limited at the given welding process. The properties of the heat affected zone will be mainly affected by the base material, while the properties of the weld metal will be affected by both, base material and filler wire selection. In particular with respect to the weld metal properties it will be difficult to obtain general quantitative information. For example, a welding consumable supplier will readily provide the properties of the filler wires but would be unable to predict the changes caused by the dilution from any base material in the weld pool and specific welding procedures that may have been used. To support the pipe mills in the selection of the consumables for submerged arc welding, an experimental program was launched with the aim to provide recommendations on how to optimize CTOD toughness of the spiral weld seam. For this, a large number of welds were produced on 20 mm thick X70 coil samples, with eight different filler wire combinations, using a 2-wire (tandem) set-up for both the inside and outside weld. Welding parameters were kept constant. The welding program was applied to two different X70 steels to determine a potential influence of the micro-alloying elements, particularly Nb. The results show clearly that a careful consumable selection is required for obtaining acceptable CTOD toughness in the weld metal. Ni-Mo and Ti-B additions to the weld metal are found to be beneficial with both steel concepts. Mo addition alone both to the ID and OD welds was clearly not a suitable selection.

Abstract:
Current design of pipelines calls for overmatching weld metal tensile strength, forcing deformation to occur in the base material and not in the weld. If straining of the weld metal were to occur, higher levels of weld metal toughness would be required to prevent fracture initiation from pre-existing defects. There are three known issues related to the Submerged Arc Welding (SAW) double jointing of pipeline steels: - Consistently achieving weld metal strength and toughness requirements. - Heat affected zone (HAZ) softening of the base material. - Lack of an accepted test protocol for the entire range of pipe grades. The results herein will help improve the quality and efficiency of SAW welding in double jointing for all pipeline steels, and enhance industry's ability to complete double jointing and standardize its acceptance, and will improve construction efficiency, pipeline reliability and safety by addressing this important research gap in transmission pipeline welding.

Full text
Abstract:
Pipeline failure due to corrosion is a common problem in the oil and gas and petrochemical industry. A cost-effective way to prevent these failures is the application of corrosion-resistant weld overlays (WOLs) onto the internal surface of line pipe. A WOL is a deposition of a filler metal - such as a nickel-base alloy - onto the surface of a part - usually carbon or low alloy steels - to introduce desired surface properties to the original substrate [1]. As such, the service life of the substrate is increased which results in reduced costs to industries such as oil and gas and petrochemical as well as to the environment. WOLs are commonly created using arc welding processes such as cold wire and hot wire gas tungsten arc welding (CW-, HW-GTAW), gas metal arc welding (GMAW), and submerged arc welding (SAW). Previous research performed at OSU indicates that a low heat input GMAW process, such as cold metal transfer (CMT), can produce WOLs which corrode up to ten times slower than overlays produced with CW-GTAW [2, 3], with up to four times higher deposition rates [4]. However, the majority of research into WOLs produced with the CMT process has been done with respect to nuclear applications, so there is a need for process optimization directed towards oil and gas applications. This project investigates the potential of CMT as an alternative to HW-GTAW for use with nickel-base alloys 625, 686 and 825 clad onto low alloy steel X65.

Mohr. L52241 Strain-Based Design - Strain Concentration at Girth Welds. Chantilly, Virginia: Pipeline Research Council International, Inc. (PRCI), December 2006. http://dx.doi.org/10.55274/r0010386.

Full text
Abstract:
Strain-based design is used for many situations for pipelines where the loadings from forces other than the internal pressure can be the largest generators of stress and strain in the pipe wall. Such loadings can be generated by soil subsidence, frost heave, thermal expansion and contraction, landslides, pipe reeling, pipe laying, and several other types of environmental loading. Designing based on strain for these cases has an advantage over designing based on stress because these loadings tend to apply a given displacement rather than a given force to the pipe. Standards are much better developed for stress-based design than for strain-based design. While several standards are available that have some coverage of strain-based design, there is a tendency to cover only limited types of loading, as in API RP 1111 for offshore pipe laying. This program aimed to improve guidelines for strain-based design of pipelines by studying cases with combinations of internal pressure and axial plastic strain in tension. Softened heat-affected zone (HAZ) regions have been observed to concentrate strain, particularly under internal pressure. HAZ softening has been observed for welds on X-70 and X-80 steels. Cases with little or no softening have also been observed for other welds in these same grades. This project extended these findings to X-100 steels, with cases of obvious softening and little or no softening observed. Higher heat inputs and larger weld volumes per pass associated with submerged arc welding (SAW) as compared to gas metal arc welding (GMAW) have been correlated with greater softening in each of these pipe grades.

Abstract:
In recent years, several pipe mills have produced heavy-wall, large diameter pipe from plates of microalloyed steels that were controlled-rolled to develop properties to meet the API 5LX Grade 70 or Grade 80 requirements and that were electric resistance welded (ERW) using advanced techniques. The use of advanced electric seam-welding practices on the steels produced using advanced steel making and processing methods offers the possibility of obtaining high strength line pipe at a lower cost than pipes produced from similar steels but with double submerged arc seam welds. The present study was undertaken to evaluate the properties of the pipe body and the ERW seam-weld region of a recently produced heavy-wall X70 line pipe. This report describes the evaluation of that pipe. The mechanical properties of the weld zone from this pipe were evaluated and reported under Task 18-89. Those data are included in this report. A high-frequency electric resistance welded (HFERW) X70 line pipe was evaluated to assess the strength properties, fracture behavior, thermal stability, and susceptibility to environmentally induced degradation that may affect its behavior in gas transmission service. A 20-inch-(508 mm)-diameter by 0.500-inch-(12.7 mm)-wall high-frequency, electric-resistance-welded (HFERW) X70 line pipe was evaluated to assess the strength properties, fracture behavior, thermal stability, and susceptibility to environmentally induced degradation that may affect its behavior in gas transmission service. The steel from which the pipe was produced was processed using advanced steel-making practices that resulted in a low sulfur content and was microalloyed with Cb, V, and Ti. The steel was controlled rolled with 75 percent of the rolling reduction being accomplished at temperatures below 1418 F (770 C); the finishing temperature was 1328 F (720 C) and the steel was hot coiled after finishing. The seam weld was produced by high frequency electric resistance welding and the seam weld region was post-weld normalized.

Payer. L51903 Damage to FBE and Liquid Epoxy Coating from Hydrogen Outgassing from Welds. Chantilly, Virginia: Pipeline Research Council International, Inc. (PRCI), May 2004. http://dx.doi.org/10.55274/r0010383.

Full text
Abstract:
Hydrogen in welds and its affect on performance from the perspective of cracking and embrittlement of steels has been widely studied, and welding procedures have been developed to minimize the deleterious effects of hydrogen. The practical problem is whether hydrogen outgassing from welds causes damage to FBE and liquid epoxy coatings on pipelines. FBE coatings on longitudinal welds made at pipe mills have developed defects because of hydrogen outgassing. Field welds are often coated shortly after welding, inspected and either buried or submerged, and there is a greater chance for more hydrogen in the field welds than mill welds. If coating damage occurred by outgassing, the damage could go undetected and affect the pipeline corrosion control. The objectives were to examine hydrogen outgassing as a cause of damage to FBE and liquid epoxy coatings, to collect and contrast experience with hydrogen in longitudinal welds and circumferential welds, to quantify hydrogen pickup and release from steel pipe and welds. Methods and practices are identified to avoid damage to FBE and liquid epoxy pipeline coatings from hydrogen outgassing. The approach was to examine epoxy coatings applied over welds for damage from hydrogen outgassing and to conduct experiments to determine the amount and rate of hydrogen desorption (outgassing) from welds. The effects of hydrogen desorption on coatings was examined for commercial FBE and liquid epoxy coatings along with screening tests with liquid glycerol and clear epoxy. Hydrogen desorption was measured directly on welds, and a model was developed to describe the outgassing of diffusible hydrogen and the amount of diffusible hydrogen remaining in the weld.

L51727 State-of-the-Art Review of Underwater Wet Welding. Chantilly, Virginia: Pipeline Research Council International, Inc. (PRCI), February 1995. http://dx.doi.org/10.55274/r0010335.

Abstract:
Offshore pipelines and platforms or other submerged on-shore pipelines are subject to in-service damage which often requires in-situ (underwater) repair. In addition, modifications or additions to these underwater systems are sometimes desirable. These operations, particularly repair, are normally on a critical path to return the systems to full operation. Wet welding is a very attractive technique for such operations in that it is more cost effective, versatile, less time consuming than applications of dry hyperbaric or one-atmosphere welding systems. In fact, this technique has been used for numerous repair operations. These operations involved a wide range of materials and structures and have produced satisfactory results. There have been a number of problems identified with wet welds and because of these problems, operators of oil and gas pipelines and offshore platform owners/users have not been able to fully exploit the advantages of wet welding. In order to more clearly define the present state-of-the-art, a literature search and an industry survey has been conducted to gather pertinent information on wet welding. Of particular interest was the feasibility of performing pipeline repairs or modifications that might require open root techniques for one-sided pipe welds. Also of interest was the impact of increasing water depth on the defect level of the resultant weld, including porosity and the subsequent leak integrity of the joint. The relevant data was then organized into general categories of information on the specific topics of wet welding and analyzed to produce this report.
