ABSTRACT:
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 the ball stud or pivoted member by heading a work-piece to provide an enlarged head portion that forms a first section of the spherical bearing surface of the ball stud, and by next forming a second head portion from a second work-piece that provides a second section of the spherical bearing surface of the ball stud. The two formed work-pieces are next welded together at confronting surfaces to provide a fused junction and the junction and spherical surface is next machined to provide the finished bearing head of spherical contour.
