Abstract

PURPOSE:To remove the concentrated stress at the toe-of-weld portion on purpose to prevent the generation of cracks without generatingthe dusts, b compressing the toe-of-weld portion until it causes the plastic deformation using the rotating compression tip, and then, by heating and repeating these treatments.
