Friction agitation jointing method of metal workpieces

摘要

A friction agitation jointing method of workpieces for subjecting the workpieces made of metals having deformation resistance or melting points different from each other to friction agitation jointing in which two of the workpieces are subjected to the friction agitation jointing while forming a peak of friction agitation force or temperature on a side of the workpiece having a larger or a higher one of the deformation resistance or the melting points relative to a bond interface between the two workpieces.
