Description

technical field

[0001] The present invention relates to a joining method using friction stir welding, and more specifically, to forming a joint portion by friction stir welding a member to be joined made of aluminum or the like, and to performing fusion welding to the joint portion of another member to be joined, or It is to reduce the occurrence of air holes when the welding defects of the joint are repaired by fusion welding.

[0002] this application claims priority based on Japanese Patent Application No. 2006-064151 for which it applied to Japan on March 9, 2006, The content is used here. Background technique

[0003] For example, as described in Japanese Patent Laid-Open No. 2000-301363, friction stir welding (Friction Stir Welding) is a joining technique in which a cylindrical rotor (tool) having a protrusion (probe) at its tip is rotated while Press the joint surface between the base metals with force, and use the frictional heat generated to soften the base metal. ...
