Abstract: The invention relates to a method for producing a resistance spot weld for connecting two or more layers of metal sheet material, comprising the following steps: step 1 : welding the layers by applying a current pulse to form a weld; step 2: reheating the weld formed in step 1 by applying a current pulse such that the edges of the weld re-melt; step 3: tempering the weld. The invention also relates to a device or part comprising two layers of steel sheet material connected by a resistance spot weld, the steel material containing phosphor and having a carbon content between 0.16 wt% and 0.40 wt%, wherein the spot weld contains tempered polygonal grains located at the edge of the weld zone.
