Friction stir welding of hollow section members

摘要

The method involves the use of a tool with an end face that can be pressed against the welding zone of the parts (1,2) to be connected and an agitation tip. The welding zone of the hollow chamber profile on the hollow chamber side is covered by an auxiliary profile (3) inserted into a holder (4). The inserted profile consists of a material whose melting point is higher than that of the hollow chamber profile material.
