Summary:

There is continued demand for cost and weight reduction as well as for improved process control in the production of P/M planetary carriers. After a brief review of sinter brazing as the primary process for the joining of P/M carrier components, capacitor discharge (CD) welding is introduced as a promising alternative.The processing of carriers by CD welding is described and the possibilities of advanced process control offered by this technology are reviewed. Subsequently, the micro-structure and mechanical properties of CD welded carriers are analyzed. Actual application validation data for ultimate and torsional fatigue as well as ultimate axial loading are presented for a two piece carrier produced from a P/M body and a stamped sheet metal spider as launched in the Ford Motor Company 5R55 transmission. Finally the processes of sinter-brazing and CD welding are compared, specifically the mechanical performance and manufacturing costs
