Abstract
The ring magnet nested on the surface of a spot welding electrode is used as the external magnetic field source. We analyzed the effects of an applied magnetic field on the appearance quality of joints, the nugget diameter of resistance spot welding for rail vehicles using stainless steel through comparative resistance spot welding experiments. A coupled electrical-magnetic finite element model was established to analyze the effect of magnetic forces on the welding current direction. Result show that the appearance of a magnetically assisted spot welding joint was significantly better than that obtained by conventional spot welding. The nugget diameter of the welding spot was also significantly increased. The Lorentz force introduced by applied magnetic field deflects the path of electrons in welding electoral field, which makes nuggets with a larger radius and a lower depth.
