Abstract
Disclosed is a friction-stir joining method for joining a first member, having a base metal covered with a substance different from the base metal, with a second member with the second member placed on the first member by moving a joining tool along a joining line having thereon a joining start point and a joining finish point. The method includes steps of: inserting the joining tool into the second member at the joining start point; moving the joining tool a predetermined distance along the joining line in a direction opposite the joining finish point; causing the joining tool to turn back at a turning-back point spaced the predetermined distance from the joining start point; moving the joining tool along the joining line to the joining finish point past the joining start point; and pulling the joining tool out from the second member at the joining finish point.
