WELDING OF TRANSFER RING ON ROUND TUBE

摘要

A triple tube shock absorber includes a pressure tube, a reserve tube and an intermediate tube. The intermediate tube is disposed between the pressure tube and the reserve tube. A control valve is in communication with the intermediate chamber. The control valve engages a transfer ring which has a saddle shaped surface that mates with the outside surface of the intermediate tube. A triangular shaped weld bead also has a saddle shape to engage the outer surface of the intermediate tube. The weld bead has a triangular shape to facilitate capacitance discharge welding of the transfer ring to the intermediate tube.
