Title: Dissimilar metal welding - by friction welding followed by diffusion welding
Inventor: SEDLMAIER JOSEF
IPC: B23K20/227
Filed: 1979-04-17
Abstract: Pieces, made of materials with greatly different melting points, have to be welded together, e.g. when the anode disc stem of an X-ray rotating-anode tube, made of molybdenum, niobium, titanium or tantalum, is to be welded to a rotor disc, made of steel. The two pieces are first subjected to a friction welding operation when one is held stationary and the other is revolved. This creates contact surfaces suitable for a subsequent diffusion welding by annealing. This avoids the fine surface prepn. required for diffusion welding and produces less scrap than the problematic high-temp. brazing operation.
