FRICTION WELDED PART AND METHOD OF FRICTION WELDING

摘要

A friction welded part, and method of friction welding, realizing design facilitation. There is provided friction welded part (1) comprising aluminum alloy made first member (10) with uniform section portion (11) having no sectional change and, friction welded thereto, aluminum alloy made second member (20) with uniform section portion (21) having no sectional change. The uniform section portions (11,21) are friction welded to each other, and heat affected part (H) occurring due to the friction welding appears in the uniform section portions (11,21) only. Desirably, each of the uniform section portion (11) of the first member (10) and the uniform section portion (21) of the second member (20) is cylindrical and the sectional dimensions thereof are equal to each other.
