LINEAR FRICTION WELDING METHOD AND LINEAR FRICTION WELDING DEVICE

摘要

Provided are a simple linear friction welding method and linear friction welding method with which it is possible to minimize the amount of burrs discharged, while forming suitable joints. 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), one member (2) and another member (4) are repeatedly made to slide on the same path, discharging burrs (8) from the interface to be welded, approximately in parallel and approximately perpendicular to the direction of sliding, and a third step in which the sliding is stopped, forming a welding surface, and is characterized in that in the second step, the interface to be welded (6) is observed from a direction approximately perpendicular to the direction of sliding, and that the stop is executed in the third step at the moment when burrs (8) are discharged approximately in parallel with the direction of sliding.
