Method of Welding a Stud To a Work Piece, and a Thermal Stud Welding Ferrule For Same

摘要

The invention provides for a method of welding a stud to a work piece using a ferrule, whereby during the stud welding process, the stud is properly centered within a bore of the ferrule and wherein molten weld material formed during the stud welding process is confined to the bore of the ferrule and gases formed during the welding are vented out of the ferrule through and upper portion of the bore. The invention further provides for a ferrule having a body having at least one rib which extends inwardly from an inner wall of the body proximate to an upper surface and which defines at least one groove. During a welding operation, the at least one rib is configured to center a stud within the ferrule, and the at least one groove is configured to allow gases formed during the welding operation to vent out of the ferrule.

主权项

1. A ferrule comprising:
a body having upper and lower surfaces and a bore extending therethrough from the upper surface to the lower surface, the bore defining an inner wall of the body, the lower surface configured to fit flush against a surface of a workpiece to which a stud is to be welded; and at least one rib extending inwardly from the inner wall of the body proximate to the upper surface, the at least one rib defining at least one groove, wherein during a welding operation, the at least one rib is configured to center a stud within the ferrule, and wherein the at least one groove is configured to allow gases formed during the welding operation to vent out of the ferrule.
