Abstract:

The performed research focuses on the complete replacement of the pipeline manufacturing process consisting in welding on SAW+MIG / MAG generators with the robotized Tandem MIG / MAG welding procedure, with low energy consumption.The Tandem MAG procedure was experimented on X52 MS steel plates destined for the manufacture of pipelines, measuring 400x150x12 mm, with Y-joints (30o).The welded joints were executed horizontally and unilaterally, with flux bed support, 3 welding seams, using for filler material two wires of the same quality, EN ISO 14341: G 42 4 M G3Si1 (Filcord C), measuring 1.2 mm in diameter, and shielding gas EN ISO 14175 (CORGON 18).The entire technological welding process was carried out in fully robotized, laboratory conditions, using the QIROX -315 welding robot, fitted with Tandem MIG/MAG welding equipment, type QUINTO-GLC 603.The welding seams were executed with the same Tandem MAG welding head, with two wires, taking advantage of the possibility to rotate the welding head so as to obtain welding seams with the wires either positioned one after the other (tandem), or transversally (perpendicular to the welding direction), obtaining, by correlation with the welding speed, optimal linear energies, implicitly, seams of various widths and penetrations.The results of the tests concerning the characterization of the obtained welded joints corresponded to the mechanical – metallographic tests, falling within the ranges provided by the applicable standards.The welding parameters used in the robotized Tandem MAG procedure may lead to remarkable advantages concerning the use of energy and filler metal. Thus, linear energies are about 40% - 45% smaller than in the case of the classical SAW+MIG / MAG process, with positive effects on the mechanical and metallographic characteristics of the welded joints, leading to significant reductions in energy consumption. Furthermore, the use of filler materials (wire, shielding gas) decreases by 10% - 15% as compared to the classical SAW+MIG / MAG process, leading, implicitly, to lower costs.As a consequence of the obtained results, MAG Tandem welding procedure may become an alternative to SAW submerged arc welding and combined SAW and MIG / MAG welding and a classical reference method for the manufacture of pipelines

Abstract:

Welding is one of the most versatile joining methods for constructing products and structures in nearly all industrial fields. Arc has been widely used as a cheap heat source for welding since carbon arc fusion welding was first applied to join Pb plates in about 1880. New welding technologies have been developed according to social needs or changes since 1960. Therefore, half-automated welding, automatic welding and highefficient welding have been developed for saving man-power and afterward full automation. First, tandem one-side SAW (submerged arc welding), high-speed rotational arc, high-heat input SAW, tandem wire MAG, etc. have been introduced as highly efficient welding processes. On the other hand, as gas-shielding arc welding processes, CO2 gas, MAG, man-power saving automatic welding, the use of a flux-cored wire, AC MIG, MIG with two wires, laser-arc hybrid welding, CMT process have been developed and most widely employed in the industries in conjunction with an advance in the welding heat sources from thyristor to inverter and nowadays digital inverter. Furthermore, robotization has been developed from spot welding robot to squire robot, multi-axes GAM robot, mobile robot, portable many-axes robot and 7 axes robot together with the development in welding sensors such as probe sensor, one-touch sensor, magnetic sensor, arc sensor, laser-slit light sensor, stereo CCD, etc. Recently, novel arc sources are not developed, but deep weld penetration and geometry are controllably obtained in TIG welding by active flux pasted on the plate surface, good use of an active gas and narrow oxidation treatment. Clean MIG process for steels is also developed by use of a unique solid-wire of double layers with different melting temperatures, and different hybrid heat sources of plasma and GMA or laser and MIG. Hybrid welding processes with CO2 laser and MAG, disk laser and MAG, fiber laser and CO2 arc or MAG has recently been applied in the shipbuilding industry. I thank the authors for their generous cooperation to the publication of new development in the welding technologies.

Abstract:

Throughout the history of modernization of welding processes, in many cases the research has focused on optimizing the location of energy in the welding area, with the continuous improvement of the quality of welded joints. The welding processes in shielding gas environment with fusible electrode (MIG-MAG) have achieved superior performances regarding the increase of the current density around of the welded joint, simultaneously with the increase of the universality degree of their application. This paper is based on researching the possibilities of concentrating energy in the welding area, seeking to obtain both more favorable energy yields and an increased quality of welded joints. In the paper are shown a some results obtained following a comparative study on 2 welding processes in MIG-MAG protective gas medium, differentiated mainly by the metal drop transfer mode: by spraying (Spray arc), respectively by synergistic transfer (Arc pulsed), applied for corner welding of alloy steel sheets.

Abstract:

Hybrid welding processes belong to a new group of welding varieties that most often combine two classic welding methods, such as laser welding with MIG/MAG welding or plasma welding with MAG welding. Modeling of welding stresses in this type of welding requires the definition of a new type of heat source model that combines a concentrated stream of energy with a classic heat source, which occurs in an electric arc. The paper presents the results of temperature field modeling in conventional MAG welding and hybrid plasma-MAG welding. In the first case, the heat source model described by Goldak was used, and in the second case, the Goldak model was combined with the developed rectangular heat source model with a homogeneous distribution. The temperature distributions obtained from the simulations were verified by spot temperature measurements during welding with thermocouples. A fairly good agreement of the numerical analysis results with the temperature measurements for MAG welding was obtained, while in the case of hybrid welding the discrepancies between the modeling and temperature measurements were greater. The results were discussed, indicating potential causes and factors influencing the obtained test results.

Abstract:

The pipelines used for carrying fluids and gas, made of specially designed steels in keeping with their intended uses, are obtained by welding on generator or by spiral welding, in a wide range of diameters (from 350 to 1800 mm) and pipe wall widths (between 6 and 40 mm). At present, the following welding procedures are used: automatic submerged arc welding (with 1 and 2 wires), combined with the unilateral or bilateral MIG/MAG welding procedure, according to plate thickness and edge working method. Ongoing researches focus on improving the end product [1, 2, 3, 4, 5, 6] by replacing the submerged arc welding procedure with other welding procedures which use less energy and have high deposit rates. This paper presents the results obtained by using tandem MAG welding, with two wires (2 x ø1.2 mm), in welding Y joint X52MS steel plates. The welds were carried out using a QUIROX 315 welding robot, with a 2-wire tandem MIG/MAG welding head, supplied by 2 QUINTO-GLC 603 welding sources, equipment found at Research Centre C12, Advanced Welding Eco-Technologies, owned by ICDD - UTBV. The results of the tests (carried out as per the enforceable regulations) concerning the characterisation of the executed welds proved that it is possible to obtain welds with lower energy use and lower material-relates costs and high productivity and quality.

Abstract:

Abstract The paper focuses on low alloy steel after innovate welding method with micro-jet cooling. Weld metal deposit (WMD) was carried out for welding and for MIG and MAG welding with micro-jet cooling. This method is very promising mainly due to the high amount of AF (acicular ferrite) and low amount of MAC (self-tempered martensite, retained austenite, carbide) phases in WMD. That structure corresponds with very good mechanical properties, ie. high impact toughness of welds at low temperature. Micro-jet cooling after welding can find serious application in automotive industry very soon. Until that moment only argon, helium and nitrogen were tested as micro-jet gases. In that paper first time various gas mixtures (gas mixtures Ar-CO2) were tested for micro-jet cooling after welding.

The droplet transition of electrical arc welding is a complicated process that combines heat, mass and momentum transfer. A high-speed camera system with laser in the background is established to observe the fast changing process of droplet transition. A group of high-speed camera pictures which indicate that the size and shape of droplet have strong uncertainty are taken and analyzed. The results show that the randomness of droplet size and shape are decided by its internal and external random factors, such as: the changing of the length of welding wire stretched out, the fluctuation of the feed speed of welding wire etc.

Abstract:

Abstract: Several studies have demonstrated the influence of parameters and shielding gas on metal transfer stability or on the generation of fumes in MIG/MAG welding, but little or nothing has been discussed regarding the emission of toxic and asphyxiating gases, particularly as it pertains to parameterization of the process. The purpose of this study was to analyze and evaluate the effect of manufacturing aspects of welding processes (short-circuit metal transfer stability and shielding gas composition) on the gas emission levels during MIG/MAG welding (occupational health and environmental aspects). Using mixtures of Argon with CO2 and O2 and maintaining the same average current and the same weld bead volume, short-circuit welding was performed with carbon steel welding wire in open (welder’s breathing zone) and confined environments. The welding voltage was adjusted to gradually vary the transfer stability. It was found that the richer the composition of the shielding gas is in CO2, the more CO and CO2 are generated by the arc. However, unlike fume emission, voltage and transfer stability had no effect on the generation of these gases. It was also found that despite the large quantity of CO and CO2 emitted by the arc, especially when using pure CO2 shielding gas, there was no high level residual concentration of CO and CO2 in or near the worker’s breathing zone, even in confined work cells.

Abstract:

During MIG/MAG welding processes in large-scale production on robotic stations, automatic quality control of the weld is often required. Determining welding defects is difficult and the reason for their occurrence is not always known. One of the conditions for a correctly made weld is stability during the welding process, which translates into continuity and increase in overall production efficiency. The article presents the results of research on the creation of a weld defect detection system combining the analysis and classification of time series of welding parameters for the MIG/MAG method along with the simultaneous analysis and classification of weld image data for robotic systems. For this purpose, the structures of deep recursive and convolutional neural networks were used. The design of a neural network with two system inputs allowing for the classification of the weld photo together with the time series for use in a robotic station is also presented. The research results presented in this article were obtained during the implementation of the project entitled „Development of a method based on the use of deep neural networks for visual inspection of welded joints in the course of R&D works” implemented at the company ZAP-Robotyka Sp. z o.o. in Ostrów Wielkopolski.

Abstract:

The vertical welding is generally considered difficult because of the danger of the flow of the melting bath and the melted slag under the action of gravity. In the case of the MIG/MAG welding process, the technological measurements that are being regarded in the ascending and descending of the vertical welding refer to: the use of transfer modes through short circuit and pulsed current, the use of core wires instead of solid wires, the crossing from the semi-mechanized to automatic or robotical welding, that allows the use of complex radial oscillation systems, that assure a good control of the metal bath. The paper wants to make a comparative technological and economical analysis between the vertical ascendent MAG welding using solid wire or core wire. The advantages that are being presented are for the use of the core wire with a rutilic core for the vertical, ascendent welding from a technological, qualitative and economical point of view in the mechanical corner welding process of a 10 mm thickness steel plates.

Abstract:

Gas-shielded arc welding of stainless steels belongs to processes which are characterized by the highest concentration of chromium (VI) and nickel in welding fume. These substances are carcinogenic to humans. Material and technological conditions of gas-shielded arc welding of stainless steels influence fume emission rates and chemical composition of welding fume. This fact creates the possibility of process optimization in aspect of emission rates and chemical composition of welding fume including carcinogenic compounds. This paper presents the correlation between shielding gas compositions and fume emission rates and carcinogenic substances contents during gas-shielded arc welding of stainless steels using MIG/MAG, Cold Arc and CMT methods.

Abstract:

Aiming at the problem of MIG welding and considering the existing analog control wire feed system has the disadvantages of low response speed, low control accuracy and poor stability. This thesis designs a set of digital control wire feed system based on LPC2132 microprocessor and introduces the control principle of wire feed motor, CAN bus interface circuit and PID control algorithm. Under the condition of power grid voltage fluctuation and load change, we do a lot of experiments. The results show that: the wire feed change rate of designed system is very small, which not only meets the requirements of JB/T-1998.MIG/MAG arc welding standard, but also greatly improves the accuracy and stability of control system.

Abstract:

The article presents examples of additive manufactured products obtained using MIG /MAG welding processes (13). The research-related tests revealed that it is possible to make products of unalloyed steels having the structure similar to castings subjected to heat treatment. Products made of maraging steel require homogenising (heat treatment). It is possible to produce bimetallic products, e.g. unalloyed steel-bronze.

Abstract:

Investigation of methods of quality improvement of weld-fabricated building constructions. It is emphasized, this issue is subject to economical, social-psychological and technical factors. To the maximum extent, quality of weld-fabricated building constructions is affected by observance of requirements for accuracy of size and shapes. Accuracy of size and shapes is subject to the values of welding deformation resulting from nonuniform heating of work-pieces in the welding process and of welding heat input. The maximum heat input is observed in the process of manual (MMA) welding, the minimum heat input is a feature of mechanized (Mig/Mag) welding). Use of mechanized methods of welding will reduce welding deformation level and improve accuracy to size of construction.Experimental investigations of butt and fillet shapes have verified the conclusion.

Abstract:

Titanium/steel clad material with excellent mechanical properties and corrosion resistance has important application in the oil, gas and ocean equipment. Due to the metallurgical incompatibility of titanium and steel, the mechanical properties of weld joint would completely lose when the brittle intermetallic phase existed in the fusion welding process. Therefore, the gas tungsten arced welding (TIG) + metal inert-gas welding (MIG) + metal active-gas welding (MAG) with pure vanadium and pure copper composite filler metals for welding connection experiment in this study was carried out on Ø610mm×(14+2)mm TA1/X65 titanium/steel clad pipe fitting (titanium cladding with thickness 2 mm, X65 pipeline steel with thickness 14 mm). The microstructure, interface element distribution, main phase, microhardness distribution on cross section and mechanical properties of butt welds were researched by using OM, XRD, EDS element mapping, microhardness and tensile tests. The result showed that the use of pure vanadium and pure copper composite filler metals for welding connection could effectively avoid the production of intermetallic compounds in the process of titanium/steel composite pipe fusion welding. The deposited metal of titanium, vanadium, copper and steel had obvious zoning, the inter-diffusion melting phenomenon was not severe, which is by using solid solution phases to transit zonings of deposited metal. The microstructure of titanium and vanadium transition interface were composed of titanium-based solid solution, the microstructure of vanadium and copper transition interface was composed of vanadium-based solid solution, and the microstructure of copper and steel transition interface were composed of copper-based solid solution. The transition interface had no porosity, crack and other defects. The tensile strength of the weld was 546MPa, which is mainly contributed by the carbon steel layer. With pure vanadium and pure copper as transition filler metal for the welding connection TA1/X65 clad pipe was successfully realized by TIG+MIG+MAG welding method, and the strength index reached the desired effect.

Abstract:

AbstractThis paper presents an overview of additive manufacturing technologies for production of metal parts. A special attention is set to wire arc additive manufacturing (WAAM) technologies, which include MIG/MAG welding, TIG welding and plasma welding. Their advantages compared to laser or electron beam technologies are lower investment and operational costs. However, these processes have lower dimensional accuracy of produced structures. Owing to special features and higher productivity, the WAAM technologies are more suitable for production of bigger parts. WAAM technology has been used together with welding robot and a cold metal transfer (CMT) power source. Thin walls have been produced using G3Si1 welding wire. The microstructure and hardness of produced structures were analysed and measured. A research was done to determine the optimal welding parameters for production of thin walls with smooth surface. A SprutCAM software was used to make a code for 3D printing of sample part.
