Abstract

See full text

The abutted face plates of frame members are joined using friction stir welding. Next, a connection member is mounted on seats formed in the frame members, while a projection of one end of the connection member is inserted into a groove of an end portion of a face plate of the frame member. Next, the other end of the connection member is temporarily welded to the face plate of the hollow frame member. With this condition, an abutted portion of the face plate and the connection member are joined using friction stir welding. Then, the overlapped portion between the other end of the connection member and the frame member is joined by friction stir welding. When the hollow frame members are welded from one side, a temporary welding of the connection member can be reduced.
