Abstract
A method for operating a double-action friction stir welding device including a welding tool having a pin member and a shoulder member, a projection/retraction mechanism for causing the pin member to project/retract relative to the shoulder member, a rotation mechanism for rotating a welding tool, and an advancing/retracting mechanism for advancing/retracting the welding tool, the method including cleaning at least one of the outer circumferential surface of the pin member and the inner circumferential surface of a through hole of the shoulder member on the basis of the level of an adhesion parameter correlated with the degree of adhesion of the material of a welding object, caused by friction stir welding, on the outer circumferential surface of the pin member and the inner circumferential surface of the through hole of the shoulder member.
