New automobile design goals focus on reducing vehicle weight along with improving structural integrity and safety standards while concurrently reducing manufacturing and assembly costs. The ability to satisfy the new design criteria will require manufacturing techniques along with new materials that exhibit increased strength, greater durability, better quality and lower costs. These characteristics parallel the attributes of powder metal (P/M) parts which continue to replace other methods of manufacture for use in various automotive applications. The paper identifies welding methods that are most often used to join P/M automotive components. Various weld procedures associated with the different methods are discussed. Examples are presented along with appropriate process information. A more detailed application development involves Gas Tungsten Arc welding a stainless P/M exhaust bushing to a wrought stainless steel tube.
