“…Zhang et al. [ 20 ] studied the impact of “EMF” in “hybrid-GMAW-laser welding” as shown in Figure 13 and it showed that the crucial impact of the external-LMF on hybrid “GMAW”-“laser-welding-arc”/“plasma” is to get the “arc-stable”, and enhance the “coupling-effect of the two heating-sources”. Under an external LMF, the arc rotated and has greater intensity.…”

“…In order to improve the quality of the joint, the researchers adopted the magnetic field‐assisted method. Zhang et al [ 64 ] noticed that the LMF can promote the coupling effect of arc and laser and form a good weld in the laser‐MIG hybrid welding of 301L. Liu et al [ 65 ] found that the stirring effect of alternating magnetic field increased the microstructure inhomogeneity of 316L joint welded by laser‐MIG hybrid welding and refined the austenite grain.…”

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.

“…Chen et al applied the magnetic field in laser-metal inert gas hybrid welding to improve the low-temperature impact toughness for 304 weld joints [15]. Zhang et al investigated the effect of external longitudinal magnetic field on arc plasma characteristics and droplet transfer during laser-MIG hybrid welding [16, 17]. However, as far as the authors’ best knowledge, until now there is no application of assisted magnetic field in HW-TIG.…”

A transverse magnetic field generator combined with high-speed hot-wire tungsten inert gas welding system is used to generate an external magnetic force to adjust the molten pool behaviours and the arc. Owing to the forward external magnetic force is helpful to balance the backward arc shear stress and the stirring of the electromagnetic force on molten pool, the weld formation and joint microstructure are improved, and the corrosion resistance of the joint is increased. The test results show that only a low level of assisted transverse magnetic field (3-5 mT) is able to significantly improve the weld formation, to refine and homogenise the microstructure, and to improve the electrochemical and atmospheric corrosion resistances of welded joints.
