ABSTRACT:
A bonding structure for a container member is disclosed. The container member has an opening and a covering member for covering the opening. The container member and covering member are abutted with each other and bonded by a friction stir welding operation. The bonding structure for the container and covering members comprises a bonding portion and a backing member. The bonding portion of the container member and the covering member is formed by inserting a friction stir welding tool into an abutting portion of the container member and the covering member. The backing member is provided for obstructing a plastic flow of materials for the container member and the covering member when the friction stir welding operation is performed. The backing member is disposed adjacent to the bonding portion, at a side of the abutting portion that is opposite to an inserting side of the friction stir welding tool.
