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.
