Abstract:
Finite element simulation is utilized in an aluminum alloy 2014 butt weld with the three kinds of welding processes, namely the filler wire Tungsten Inert Gas (TIG) welding, the laser welding and laser-TIG hybrid welding. The simulated results are in good agreement with the weld cross sections for the TIG and the laser welding, and basically in agreement with that for the laser-TIG hybrid welding using the actual welding parameters. Furthermore, the simulated results shown that the longitudinal residual stresses after welding are the largest for the laser welding and the laser-TIG hybrid welding, the maximum of which are approximate to 300MPa and are 1.2 times of that for the TIG welding. However, the residual stresses would be relatively decreased by backing molten with TIG welding and preheating before welding; the maximum longitudinal residual stresses for the laser welding and the laser-TIG hybrid welding could be decreased remarkably by about 50%.

Abstract:
Joining of dissimilar materials has gained a lot of interest in the recent years due to the increased demand of high strength and light weight designs. Fusion welding plays a vital role in repairing and manufacturing industries like automobile, construction, ship building, and energy sector. Tungsten inert gas (TIG) welding is more advantageous over other welding processes as it produces high precision welds with aesthetic appearance. The limitation of the process is shallow penetration, distorted and weaker joint formation, and low productivity. In the present work, a critical review and analysis has been done on weld penetration and its enhancement during TIG, activated flux TIG, and pulsed current TIG welding of steels. The purpose of this review is to raise an insight about using the variants of TIG, minimising the energy consumption and heat affected zone while increasing the weld penetration and productivity. Proper selection of welding parameters along with welding speed, electrode diameter, shielding gas, electrode tip angle, arc gap, and flux greatly increase the weld penetration.

In this particular work, the moving Gauss heat source model based on the gas tungsten arc welding and a new heat source model based on the laser-TIG hybrid welding were developed by the finite element analysis according to the physical characteristic of the TIG welding and the laser-TIG hybrid welding, Taking into account the advice of parameter modification, the modeling was respectively carried out by the single TIG and the laser-TIG hybrid welding for AZ31B magnesium alloy. The welding temperature field and the weld cross-section geometry were simulated separately with regard to dependence on the single TIG and the laser-TIG hybrid welding. Comparing the experimentally measured value with simulated value of the weld section geometry, the simulated and the experimentally determined weld section geometry by the single TIG welding and the hybrid welding showed a good agreement, at the same time, the microstructures of the joint were also discussed respectively.

Abstract:
Laser aided activating TIG welding was called LA-TIG. At first, the surface of weld was melted by the mini power laser protected by oxygen, and then the conventional TIG was used to cover the weld, which achieved the target of the weld with deeper penetration and narrower width. In this article, the weld bead morphology, arc images, microstructures and mechanical properties of laser aided activating TIG welding joint were analyzed. The results shows that the penetration increased significantly, excellent weld appearance and finger shape penetration were gained by laser aided activating TIG welding. It was found that the arc images of the LA-TIG was only the enlarged form compared with which observed in the conventional TIG and the arc constriction was also observed. LA-TIG weld exhibits better mechanical properties than the conventional TIG welding. Thus laser aided activating TIG welding was developed as a novel active welding method.

Abstract:
Abstract Austenitic stainless steel (ASS) is widely fabricated by tungsten inert gas (TIG) welding for aesthetic look and superior mechanical properties while compared to other arc welding process. Hitherto, the limitation of this process is low depth of penetration and less productivity. To overcome this problem activated tungsten inert gas (A-TIG) welding process is employed as an alternative. In this investigation the welding performance of conventional TIG welding is compared with A-TIG process using TiO2 and SiO2 flux with respect to weld bead geometry. The experimental investigation on A-TIG welding of ASS-201 grade shows TiO2 flux helps in achieve higher penetration as compared to SiO2 flux. While welding with SiO2 the hardness in HAZ and weld region higher than that of TIG welding process.

Abstract:
This paper studied and framed TIG and A-TIG welding procedure of LY12 aluminum alloy and analyzed the metallurgical structure and hardness of weld zone of TIG and A-TIG under different welding current. The result showed the strengthening phase which separated out from the basal body of TIG weld zone was obviously fewer than A-TIG and the strengthening phase of TIG obviously decreased when welding current increased. Compared with TIG weld zone, surface activating flux changed the metallurgical structure of A-TIG weld zone and the strengthening phase of A-TIG weld zone was more than TIG. The strengthening phase of A-TIG weld zone did not obviously decreased when welding current increased that implied the strengthening phase of A-TIG did not obviously dissolve into the basal body as TIG and only coarsened with the increase of welding current. The hardness experiment of weld zone showed that the hardness of A-TIG weld zone was higher than TIG and the hardness of 60%NaF+40%SiO2 activating flux of A-TIG weld zone was higher than 40%NaF+60%SiO2 activating flux.

Abstract:
Direct current A-TIG (DCEN A-TIG) welding using special active agent had eliminated the pores and the oxidation of 2219 high-strength aluminum alloy in welding. Addition of AlF3–25% LiF active agent to DCEN A-TIG welding and arc morphology showed a trailing phenomenon. However, the change in arc morphology was not remarkable when AlF3–75% LiF active agent was added. Addition of AlF3–75% LiF active agent can refine the grain size of DCEN A-TIG joint. The mechanical properties of the weld were optimal at 10% AlF3–75% LiF active agent. Compared with AC TIG and AC A-TIG welding, DCEN A-TIG welding yielded better results for 2219 Al alloy.

Abstract:
Tungsten inert gas welding (TIG) is more stable and allows for more precise control than most other arc welding processes. TIG welding is desired in the aerospace sector when thin parts have been welded with accuracy. However, when welding thick sections, autogenous TIG welding is not commonly recommended due to the limited depth of penetration required. It is in effective for joining the thick parts in a particular pass. Welding with activated flux tungsten inert gas (A-TIG) enhances weld penetration by four times in a single pass. This process will improve penetration depth, depth/width ratio and also, minimize angular distortion and residual stresses. A-TIG is the topic of investigation among researchers due to its deep penetration capacity. Properties of A-TIG welding in diverse materials was investigated in this study which also discusses the mechanisms, varied forces like lorentz force, buoyancy force, shear stress prompted by plasma jet, shear stress prompted by surface tension gradient, reverse marangoni force and aerodynamic drag force induced in the weld pool. The impact of activated fluxes on various materials of A-TIG weld was also investigated in this study. Recent advancements in TIG welding methods were also explored. According to the findings, A-TIG welding improves weld penetration significantly, but there is a lot of slug on the weld surface. This constraint can be addressed by using new versions of the A-TIG welding progression, such as flux bounded and the flux zone.

Naseer-Ahmed. "Synergic control in MIG welding and penetration control in TIG welding." Thesis, London Metropolitan University, 1992. http://repository.londonmet.ac.uk/3451/.

Full text
Abstract:
Part 1: Synergic control in MIG welding. Synergic controls (i.e. real time control methods) for both steady DC open arc and short circuiting arc operations have been developed in this study. These have been based on the generalised quadratic and linear ‘power-current' and linear ‘voltage-current’ equations which adequately describe the MIG welding operation. The controls are low coat electronic units which are added to a ‘transistor’ controlled power source. The units based on the ‘power-current’ concept can operate with the power source set in the constant current, constant voltage or any intermediate mode of output characteristics, and regulate only the steady DC open arc operation. The unit based on the ‘voltage-current’ concept operates with the power source set in nominally constant voltage mode, and regulates both steady DC open arc and short circuiting arc operations. These controls adjust the current, voltage or power automatically according to any operator-selected wire feed speed whether maintained constant at any level, varied gradually or modulated with any waveform to achieve ‘thermal pulsing’. In addition, two approaches have been used to adapt the synergic control units to a lower cost, thyristor controlled power source which is more widely used in industry. In one approach, the generalised control equation used previously for the transistor controlled power source has been extended to take account of the output characteristics of the thyristor controlled power source. As an alternative, the control units themselves have been modified to allow for the different power source characteristics. The control systems have been successfully demonstrated for producing sound welds in a wide range of welding applications, for both mechanised and manual welding techniques. Part II: Penetration control in TIG welding A 'backface' penetration control system developed at Liverpool University, based on a ‘video camera' instead of a ‘photodiode' as a sensor, has been evaluated at The Welding Institute. Essentially, the system controls the size of the weld pool, instead of an average level of radiation, by regulating pulse current period, by means of a fibre optics image guide/video camera/microcomputer based controller. The system has been found to be capable of controlling the weld bead penetration uniformly in stainless steel plates and joints, for constant as well as variable material thicknesses. However, the system cannot be used with high frequency (HF) arc discharge, as required for automatic arc initiation, because the software and electronic components are corrupted. A hard-wired control unit has therefore been developed at The Welding Institute to replace foe microcomputer based controller. This unit can be operated reliably with automatic HF arc initiation. Furthermore, it has been shown to control weld bead penetration in stainless steel plates and joints, for constant at well as variable material thicknesses.

Abstract:
In this master thesis different overlay welding methods suitable for boiler application has been investigated. The purpose of this project is to define advantages and disadvantages for each overlay welding methods and suggest some evaluation criteria on some commercial and experimental alloys aimed for overlay welding material. Many components in a boiler are made of low alloy steel and the atmosphere in the furnace region can be very complex; therefore many different types of corrosion can occur. Weld overlay is a process where one or multiple layers of corrosion resistant material are applied to a base material. The two overlay welding methods investigated in this study were Tungsten Inert Gas welding and Metal Inert/Active Gas welding. Tests were performed with FeCrAl alloys (Kanthal A, Kanthal D and some experimental alloys). FeCrAl alloys in general are ferritic iron-based steels with a typical concentration of 20-23 wt. % chromium and ~5 wt.% aluminum. Different overlay welding evaluation was made; visual examination, dye penetrant inspection, macro/micro examination, side bend test and short term corrosion test (~50hours). Conclusion of this thesis is that MIG welding is a more productive method than TIG, but more defects such cracks and lack of fusion can be produced for MIG welding. These defects can be “fixed” if welding parameters is optimized. If repairing a certain place TIG welding is a better option. A conclusion about number of layers; one layer with MIG welding is almost as thick as three layers with TIG welding with welding wire Ø 1mm. Three welding evaluation that is really important is visual examination, dye penetrant testing and corrosion test in order to choose which overlay welding method is suitable in boiler application.
I detta examensarbete har olika påsvetsningsmetoder som är lämpliga för en pannapplikation undersökts. Syftet med denna studie var att undersöka både för- och nackdelar med påsvetsningsmetoderna och föreslå några utvärderingskriterier på vissa kommersiella och experimentella legeringar som lämpar sig för påsvetsningsmaterial. Många komponenter i en panna är tillverkade av låg legerat stål och miljön där förbränningen sker kan vara väldigt komplex, därför kan det ske korrosion. Påsvetsning är en process där ett eller flera skikt av ett mer korrosionsbeständigt material appliceras på ett basmaterial. De två olika svetsmetoderna som undersöktes i denna studie var TIG-svetsning och MIG-svetsning. Testerna utfördes med FeCrAl legeringar (Kanthal A, Kanthal D och vissa experimentella legeringar). FeCrAl legeringar är i allmänhet ferritiska järnbaserade stål med 20-23% krom och ~5% aluminium. De utvärderingsmetoderna som undersöktes var: visuell undersökning, penetrantprovning, makro/ mikroundersökning, sidobockprovning och korttidskorrosionstest (~50 timmar). Slutsatsen av detta examensarbete är att MIG-svetsning är en mer produktiv metod än TIG, men fler defekter såsom bindfel och sprickor uppkom för MIG-svetsning. Dessa defekter kan ”fixas” genom optimering av svetsparametrar. Om man bara ska reparera ett specifikt område är TIG-svetsning ett bättre alternativ. En slutsats om antal lager är att ett lager med MIG-svetsning är nästan lika tjockt som tre lager med TIG-svetsning med Ø 1mm svetstråd. Tre svetsutvärderingar som är viktiga är visuell undersökning, penetrantprovning och korrosionstest för att välja vilken påsvetsmetod som är lämpligast i pannapplikation.

Abstract:
Argon TIG arc temperatures have been measured for a wide range of arc parameters using the 'Fowler-Milne' spectroscopic method. Prompted by widespread disagreement amongst temperatures published by previous groups, a detailed investigation has been carried out into those experimental and theoretical aspects of the measurement process that may have led to incorrect results. The tests have included the variation of experimental parameters, the choice of Abel inversion procedure, and the calculation of argon species number densities and partition functions. The existence of equilibrium within the TIG arc has been investigated by determining temperatures with a number of argon emission lines. Significant differences 'in derived values of the temperatures were observed within 1mm of the tungsten cathode tip, smaller variations were observed over the remainder of the arc. The results indicate that large scale departures from a Boltzmann distribution amongst argon atom excited states exists close to the tungsten tip, deviations decrease with increasing distance from the tip but do not disappear completely. lt is believed that the breakdown of equilibrium within the argon TIG arc may help to explain the disagreement in temperatures obtained by past groups that have used spectroscopic methods. Despite evidence for non-equilibrium within the arc. results from previous groups suggest that derived values of .the temperatures are substantially correct in the main body of the arc. The detailed temperature maps provide useful information on temperature changes with arc parameters for the purposes of modelling and understanding of the arc.

Different problems arise from choice of setting technological parameters during welding of alluminium alloys. Choice of welding method, welding speed and material influence mechanical properties of welds. During welding of alluminium alloys come difficulties due to oxidation of thin surface layer of material. One of ways how to overcome this obtacle is to use hybrid laser-TIG welding method. In this diploma thesis is described influence of welding processes on mechanical properties of two alluminium alloys(EN AW-5754 H22, EN AW-6082 T6) and change in their microstructure during welding.

Abstract:
The goal of this research was to design and test an experimental setup capable of performing a TIG welding process and acquiring temperature measurements near the weld with the use of an infrared spot sensor. The data collected can then be used to validate a computer simulation that models the exact same process. An experimental setup was built, and preliminary temperature data were collected. It was determined that infrared measurements taken at the arc contain excessive amounts of interfering radiation emanating from the welding zone. The optimal angle of orientation is normal to the weld line. In this way an infrared spot sensor can be focused on an area just down weld of the arc where the temperatures remain relatively high and thermal gradients, although still large, are at a minimum. Additional data were collected from thermocouples to validate the infrared sensor results and also to provide additional data that can be compared to a computer model. Sources of error were identified and recommendations were made as to how they can be avoided or minimized.

Abstract:
O conjunto de tubos denominado sistema pneumático, tem a função de conduzir o ar quente pressurizado desde o motor até os pontos de utilização pelos sistemas ambientais da aeronave. A ocorrência de falhas em serviço de peças desse sistema soldadas pelo processo TIG (Tungsten Inert Gas), motivou o estudo da substituição desse processo pelo de soldagem a laser. Foi utilizado um laser a fibra de 2 kW de potência e tubos de titânio comercialmente puro grau 2, de 0,5 mm de espessura e 50 mm de diâmetro. Para efeito de comparação foram realizadas soldas pelo processo TIG, semi-automático, cujos parâmetros foram obtidos junto a uma empresa fabricante de aviões. Os tubos de titânio foram soldados em cheio, sem adição de arame, e o argônio foi utilizado como gás de proteção. Os parâmetros de soldagem a laser selecionados foram 200 W e 2000 mm/min e, 250 W e 300 mm/min. Os tubos soldados a laser apresentam cordões com aproximadamente 1 mm de largura e grãos de Ti-CP ?, enquanto que as soldas TIG resultam em cordões de 5 mm e grãos grosseiros serrilhado de Ti-CP ?. O refinamento microestrutural observado nas amostras soldadas a laser, em relação à TIG, deve-se a alta taxa de resfriamento, que no laser foi cerca de 70 vezes maior do que no TIG. Os tubos soldados a laser e TIG foram ciclados na bancada pneumática, 44.000 vezes, a 350 oC, sem fraturarem ou iniciarem uma trinca que comprometesse os testes de pressurização cíclica. Os resultados de fadiga evidenciaram uma maior resistência mecânica da solda a laser na condição de 200 W e 2000 mm/min, quando comparado com as demais condições de soldagem. As avaliações microestruturais e mecânicas dos cordões de solda evidenciaram as vantagens do processo de soldagem a laser para substituir o TIG, em junções do sistema pneumático de aeronaves.
The engine bleed air system, also known as pneumatic system, conducts the pressurized hot air from the engine to the environmental systems of aircrafts. In-service failures of the arc welded pneumatic parts have driven further developments of laser beam welding as an alternative method. Here, a fiber laser with 2 kW power had been employed to weld commercial purity titanium alloy tubes with 0.5 wall thickness and 50 mm diameter. For comparison purposes, semiautomatic TIG welding was realized, based on the previous experience of an aircraft company. All the welds were autogenous, bead-on-plate, and under protective argon atmosphere. The chosen parameters speed and laser powers for laser welding were 200 W - 2000 mm/min and 250 W - 300 mm/min. The laser welded tubes presented 1-mm wide weld beads composed by grained ?-Ti. The TIG welded tubes showed 5-mm wide beads composed by acicular ?-Ti grains. These observed differences had been associated to the cooling rate, which is seventy times higher in the laser case. Both laser and TIG welded tubes were cycled 44.000 times in a pneumatic bench at 350 oC without failures or cracks that could break the internal pressure. The condition 200W-2000mm/min presented superior fatigue resistance values compared to other welding conditions, and being similar to the tubes in the unwelded condition. On the other hand, the condition 250W-3000mm/min presented the highest dispersion for the fatigue lives. The microstructural and mechanical results shown that the current laser technology could replace with advantages the arc welding for the joining of the titanium tubes in the aircrafts pneumatic system.

Abstract:
Shape memory nickel-titanium (NiTi) is attractive for use in solid-state actuators as it exhibits large recoverable stresses, limited by its ultimate shear strength of over 120 ksi (960 MPa), and large recoverable strains, up to 8%. Broad application of NiTi is hindered by the expense, complexity, and lack of reliability in machining and joining it to structural materials. This paper investigates the use of orbital Tungsten Inert Gas (TIG) welding to join NiTi to 304 stainless steel (304 SS), a common structural material that can be readily machined and welded. Tubes of NiTi and 304 SS were joined using a nickel filler to mitigate the formation of brittle intermetallics. Both tubes had a 0.375 in (9.53 mm) outer diameter with wall thicknesses of 0.065 in and 0.075 in (1.7 mm and 1.9 mm) for the 304 SS and NiTi tubes, respectively. Viable joints were created and characterized through X-ray analysis, optical microscopy, hardness mapping, and strength testing. The joints had an average failure torque of 450 in-lb (52 N-m), corresponding to an ultimate shear strength of approximately 50 ksi (350 MPa). This was sufficient to detwin the NiTi in the tubes, which occurs at a shear stress of 16 ksi (110 MPa), and plastically deform the annealed 304 SS tubes. Optical microscopy and hardness mapping revealed a heat-affected zone 0.005 in (125 μm) wide with a maximum hardness of 817 HV. Outside of this heat-affected zone the hardness was not affected, indicating that no large-scale loss of superelastic or shape memory properties arises from TIG welding.

FATIGUE PERFORMANCE OF RIB-TO-DECK JOINTS STRENGTHENED WITH INTERNAL WELDING. The Hong Kong Institute of Steel Construction, August 2022. http://dx.doi.org/10.18057/icass2020.p.268.

Full text
Abstract:
"Rib-to-deck joints of orthotropic steel decks (OSDs) in steel bridges are susceptible to longitudinal fatigue cracking, which often results in considerable costs as well as traffic interruption. This paper numerically simulated the Crack II of rib-to-deck joint and analyzed the crack failure mode of the joint. To mitigate such cracking, a strengthening method using internal welding was investigated. The effects of initial crack size, internal weld size and crack depth on the stress intensity factor (SIF) of crack tip on rib-to-deck fatigue details were studied by finite element method. The finite element analysis demonstrated that the proposed method can significantly improve the detailed stress range of the weld root, lead to the transfer of crack development mode, and prolong the fatigue life of rib-to-deck joints. Numerical analysis validated the beneficial effect of strengthening measures on the stress intensity factors at crack tips. Calculation of stress intensity factors at crack tips resulted that the crack development law, and the application range of reinforcement method was analyzed. This study provided a reference to the design and application of internal welding in the strengthening of weld details in OSDs."

HYSTERETIC PERFORMANCE OF WEAK-AXIS CONNECTION WITH I-SHAPED PLATES IN STEEL FRAME. The Hong Kong Institute of Steel Construction, September 2021. http://dx.doi.org/10.18057/ijasc.2021.17.3.1.

Full text
Abstract:
This paper elucidates numerically the behavior of weak-axis moment connections proposed by welding I-shaped plates in the H-section column to increase connection strength and ductility in steel frame. After validating the numerical methods through comparing the results of numerical analysis and experiments, the effectiveness of the proposed weak-axis connection were examined through comparing to the traditional weak-axis connection. The proposed weak-axis connection could move the highest stresses away from the start-stop points of a weld, and thus preventing the premature brittle fracture of the beam flange welds. The plastic hinge formed away from the beam-column interface, while the local buckling occurred in the weld access holes region in the traditional weak-axis connection. The proposed weak-axis connections can be classified as rigid in a strong-bracing system, and be classified as semi-rigid in weak-supported or unsupported system. And then a series of parametric studies was conducted to better understand the behavior of proposed weak-axis moment connections. The force-displacement relationships, location of the plastic hinge, Mises index (MI), triaxiality index (TI) and rupture index (RI) distributions at the beam flange welds were reported in detail. According to the numerical analysis, the design variables of I-shaped plates and widened flange plate are suggested, along with a design procedure.
