More Information
Summary:A spot friction welding tool is for performing spot friction welding of a first member and a second member by superposing the first member and the second member and pressing the spot friction welding tool against the first member and the second member from the first member side. Each of the first member and the second member is a steel plate having a tensile strength of not lower than 590 MPa. The spot friction welding tool is rotatable around a rotation axis. The spot friction welding tool includes a column having a shoulder at a tip end thereof, and a cylindrical or truncated conical probe protruding from the shoulder in a direction of extension of the rotation axis.
