Abstract
A fatigue-resistant welded joint between structural members and process for making same, as for an automotive bracket, are shown. A filler metal-containing reprocessing weld is applied over at least part of a toe of a small primary structural weld at the joint, the reprocessing weld extending onto the weld face area and onto the structural member area immediately adjacent to the covered toe portion. The total welding energy input used for the reprocessing weld is less than the welding energy input used for making said primary structural weld, and the cross-sectional area of the reprocessing weld is less than the corresponding cross-sectional area of the primary structural weld.
