Title:
LINEAR FRICTION WELDING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/143334
Kind Code:
A1
Abstract:
Provided is a linear friction welding method with which it is possible to form a suitable joint, even with thin sheets having a sheet thickness not exceeding 3 mm. This invention 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 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 weld surface, and is characterized in that at least one of the one member (2) and the other member (4) is a thin sheet having a thickness not exceeding 3 mm, and pressure is set to at least the yield stress of the thin sheet at the welding temperature, and burrs (8) are discharged.
