JOINING METHOD
Document Type and Number:
WIPO Patent Application WO/2016/181770
Kind Code:
A1
Abstract:
Provided is a joining method by which it is possible, during friction stir welding, to prevent metal members shifting out of position and the metal members from separating, and by which deformation of metal members can be corrected. The method is characterized by including: a butting step for butting the rear surface (1a) of a first metal member (1) and an end surface of a second metal member (2); a welding step for carrying out welding of inside corners which are formed by the rear surface (1a) of the first metal member (1) and side surfaces (2a, 2b) of the second metal member (2); and a friction stirring step for inserting a stirring pin (G2) of a rotary tool (G) from the first metal member (1) front surface (1b) side, moving the rotary tool (G) along a butted part (J), and carrying out friction stir welding on the butted part (J) in a state in which the stirring pin (G2) contacts the first metal member (1) only, or both the first metal member (1) and the second metal member (2); in the friction stirring step, friction stir welding of the butted part (J) takes place while a shoulder part (G1) of the rotary tool (G) is pressed against the front surface (1b) of the first metal member (1).
