Effects of Magnetic Fields in Arc Welding, Laser Welding, and Resistance Spot Welding: A Review

The pictures show the effect of magnetic fields in different directions, including welding direction, transverse, longitudinal and cusp magnetic fields, on the shape of welding arc and molten pool. The magnetic field can significantly affect the arc morphology and droplet transfer, as well as the macro morphology and microstructure of the weld bead.
