Title:
JOINING METHOD, AND JOINED STRUCTURE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2009/022543
Kind Code:
A1
Abstract:
Provided are a joining method and a joined structure manufacturing method, which
can improve the gas-tightness and the water-tightness of a joined metal member.
The joining method frictionally stirs a joined metal member (1), which is formed
by causing a first metal member (1a) and a second metal member (1b) to abut against
each other. The joining method comprises a first joining step of frictionally
stirring the front surface (A) of the joined metal member (1) at the abutting part
(J1) between the first metal member (1a) and the second metal member (1b), a second
joining step of frictionally stirring the back surface (B) of the jointed metal
member (1) at the abutting portion (J1), and a side welding step of welding the
side surface of the joined metal member (1) at the abutting portion (J1). The joining
method is characterized in that the side welding step seals up the unplasticized
region between a surface-side plasticized region (W1) formed during the first
joining step and a back-side plasticized region (W2) formed during the second
joining step, with weld metal (T).
