<p>PROBLEM TO BE SOLVED: To provide a joining method capable of easily flattening a joined metallic member.SOLUTION: A joining method includes a preparation step of forming a butting part J by butting mutual end surfaces 1a and 1a on one end side of a pair of metallic members 1 and 1, a first regular joining step of executing frictional agitation to the butting part J from the surfaces 1b and 1b side of the metallic members 1 and 1 and a second regular joining step of executing welding to the butting part J from the reverse surfaces 1c and 1c side of the metallic members 1 and 1. In the first regular joining step, the frictional agitation is executed in a state of inclining the metallic members 1 and 1 so that one end side becomes higher than the other end side of the metallic members 1 and 1, a burr generated by the frictional agitation is removed and the metallic members 1 and 1 are reversed after finishing the first regular joining step, and the welding is executed while cooling by a cooling plate K disposed on the surfaces 1b and 1b side of the metallic members 1 and 1 in the second regular joining step.</p> |
