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.

Experiments have been conducted to investigate the influence of the cusp external magnetic field (EMF) on deposition rate of two-electrode tungsten insert gas (T-TIG) welding.T-TIG arc parameters such as arc shape, arc voltage, arc pressure and arc plasma information were acquired respectively. Results showed compared to TIG, a higher welding current could be allowed for T-TIG, due to its low arc pressure characteristic. Under the effect of the cusp EMF, the arc shape was compressed along x-axis of T-TIG, while elongated along y-axis of T-TIG. Besides, the peak arc pressure of T-TIG was not significantly increased by the cusp EMF.Moreover, with the action of the cusp EMF, the maximum values of the electron temperature (Te) and electron density (Ne) of T-TIG were not significantly increased, but along y-axis, the increments of the two parameters were gradually increased and their distributions were widened. Therefore, more arc energy was allocated on y-axis of T-TIG by the cusp EMF, which could improve the preheating and the melting of the filler wire along y-axis, so the deposition rate of T-TIG could be increased by 17.6% under the effect of the cusp EMF.
