A1
Abstract:
Provided is a method for operating a double-action friction stir welding device, wherein: the double-action friction stir welding device comprises a welding tool (51) having a pin member (11) and a shoulder member (12), a projecting/retracting mechanism that projects and retracts the pin member (11) in relation to the shoulder member (12), a rotation mechanism (533) that rotates the welding tool (51), and an advancing/retracting mechanism (532) that advances and retracts the welding tool (51); and the operation method includes cleaning (B) the outer peripheral surface of the pin member (11) and/or the inner peripheral surface of a through-hole (13) in the shoulder member (12), the cleaning (B) being performed on the basis of the level of an adhesion parameter correlated with the degree of adhesion of the material of a welding object (60) generated by the friction stir welding to the outer peripheral surface of the pin member (11) and the inner peripheral surface of the through-hole (13) in the shoulder member (12).
