... stir-welded joints were 60% stronger than comparable riveted or resistance spot-welded joints. The stir-welded joint does not demonstrate many of the defects encountered in normal fusion welding, and the distortion is significantly less. A typical weld joint ( Fig. 6.20 ) contains a well-defined...
