摘要：
A method of producing ball joints of the type that include a ball and stem member pivotally mounted in a housing, the method comprising forming separate stem portions and ball portions and joining the portions at welded junctions with frictionally impored heat to provide pivot members of composite construction. Such pivot members are characterized by relatively large ball diameters as compared to the shank diameters so as to provide a high degree of angularity of movement.
