Abstract:During resistance spot welding (RSW), the thermal cycles that occur cause microstructural differentiations in the heat‐affected zones of martensitic steels, leading to internal stresses. In this context, a new and innovative methodology has been developed to minimize the adverse effects of heterogeneous hardness changes in the welding area on joint durability. This methodology utilizes a unique prototype setup based on the regional rapid cooling (RRC) process, which is integrated into the welding machine and o… Show more
