TOOL FOR FRICTION STIRRING WELDING

摘要

PROBLEM TO BE SOLVED: To provide a tool having a cutter to remove burrs developed during a friction stirring welding. SOLUTION: A first member 20 and a second member 30 are butted on their welded ends 40, and the upper faces of protruding parts 22 and 23 formed on each member are welded with a tool for friction stirring welding 100. The tool for friction stirring welding 100 has a cylindrically formed main body 110 and a bur cutter 150 which is integrally formed with the peripheral part of the main body 110. By rotating the tool 100, the burrs developed during the friction stirring welding are removed as chips 62.
