“…Some researchers have also studied the effect of pulse current and pulse frequency on dissimilar welded joints. Liu and his research team outlined the application of a robot in a mass manufacturing environment with the help of an axisymmetric applied magnetic field in the weld zone of the lap joint with an overlap distance of 10 mm between a red copper T2 plate and an aluminum alloy 6061-T6 plate [74].…”

In recent years Gas Metal Arc Welding (GMAW) technology has expanded its functionalities in various areas which have further motivated its usage in several emerging manufacturing industries. There are several issues and challenges associated with this technology, especially in dissimilar metal welding (DMW). One of the predominant challenges is selecting appropriate welding parameters which influence the efficiency of this technology. To explore several modern advancements in this expertise, this paper has done an exclusive survey on various standards of GMAW and its variants for selecting suitable parameters for welding dissimilar nonferrous metals. This review summarizes various experimental and numerical results along with related illustrations to highlight the feasibility of welding dissimilar nonferrous metals using traditional GMAW and investigations on advanced GMAW processes such as cold metal transfer (CMT) and pulsed GMAW (P-GMAW). Simulation and modeling of nonferrous DMW have identified several research gaps and modeling problems. Researchers and manufacturers can use this review as a guideline to choose appropriate welding parameters to implement GMAW and its variants for non-ferrous dissimilar welding. It found that by controlling the heat input and effective post-heat treatments, adequate joint properties can be achieved. Automated large -scale manufacturing will widen the utilization scope of GMAW and avoid some costly methods such as laser welding, ultrasonic welding, and friction stir welding etc.

“…This inhibition of IMC formation has also been seen in magnetic field‐assisted laser welding (MALW) of Al/steel [ 45 ] and Al/titanium. [ 46 ] The application of AMF in CMT welding of Cu and Al was found to lower the average heat input and the thickness of Al 2 Cu IMC, [ 47 ] as well as improve the joint strength. In the connection of 6061Al and pure titanium, [ 48 ] the AMF increases the wettability and fluidity of the welding wire, reduces the thickness of Ti 3 Al IMC, and improves the mechanical strength by 93.4%.…”

The application of magnetic field in welding process has been proved to be effective in improving the mechanical properties of welded joints and is regarded as a practicable auxiliary welding method. Although the theoretical research on magnetic field‐assisted welding is quite abundant, there is still a long way to go before a stable industrial application is achieved. Therefore, to clarify magnetic field and compare its roles in various welding techniques, this work carefully examines the use of magnetic field in recent welding techniques such as laser welding, laser‐melt inert gas hybrid welding, gas metal arc welding, tungsten inert gas welding, and resistance spot welding. Based on previous experiments and simulation research results, the effects of the Lorentz force on the arc, molten pool, and dendrite solidification during welding as well as the microstructure and mechanical properties of welded joints are discussed. The purpose of this work is to give a superficial introduction to the magnetic field‐assisted welding method in recent years, hoping to improve the welding practitioners’ understanding of the magnetic‐assisted welding method and provide a reference for researchers who use different welding methods.

“…Schneider et al [10] found that porosity defects in the aluminium alloy were decreased obviously when the frequency and intensity of the alternating magnetic field were sufficient. Besides, influencing mechanism of magnetic field on welding has been studied by some scholars [11, 12]. The keyhole stability and energy distribution in molten pool could be changed by magnetic field.…”

Steady magnetic field with both orientations including longitudinal magnetic field (LMF) and transverse magnetic field (TMF) was used. The influence of LMF and TMF on weld formation, porosity and mechanical property of 5052 aluminium alloy laser-gas metal arc (GMA) hybrid welding was investigated. The shielding effect of hybrid plasmas on laser energy was weakened by TMF, leading to an increase in weld depth under TMF. Porosity rate was significantly reduced to 2.61% under TMF, because keyhole stability was improved, escaping channels for bubbles were increased, and solidification time of molten pool was prolonged. As a result, the highest tensile strength (174.7 MPa) of hybrid weld was obtained at TMF, owing to the lowest porosity rate.
