ABSTRACT:
In order to weld a cup-shaped member to a ring, claws are secured to the exterior surfaces of each part. In addition, a resilient member such as a ductile aluminum plate is placed between each pair of claws. The parts are spaced apart to form a gap in which a welding seam can be made. During cooling, the welding seam shrinks. This causes the aluminum plates between the claws to plastically deform. Thereafter, the claws and plates can be removed and the finished welding carried out.
