Provided is a linear friction welding method with which it is possible to accurately control the welding temperature, and reduce the welding temperature to a low temperature. This method comprises a first step in which one member (2) is brought into contact with another member (4) to form an interface to be welded (6), a second step in which, with pressure being applied approximately perpendicularly with respect to the interface to be welded (6), the one member (2) and the other member (4) are made to slide repeatedly on the same path, discharging burrs (8) from the interface to be welded (6), and a third step in which the sliding is stopped to form a welded surface, characterized in that the pressure is set to at or above the yield pressure but not exceeding the tensile strength of the one member (2) and the other member (4) at the desired welding temperature. |
