ABSTRACT:
A weld preparation process that translates a consumable or nonconsumable tool over an area that is subsequently to be welded to impart friction heating to the surface. Rotary or linearly oscillated motion between the tool and the workpiece is used to generate heat and produce deformation in the surface, resulting in recrystallization of the area being processed and a compressive residual stress.
