Abstract
A part of hard, weldable material which has been through drilled and tapped is sealed by stud welding a stud thereover to form a fluid-tight article which is used to facilitate the connecting of other parts. The threads are protected during stud welding by a conductive refractory insert in the tapped through bore thereby preventing molten metal or the like from entering the same. A magnetic jig serves to hold the insert and as an electrical connector of the insert to the part to permit the proper arc to be drawn during stud welding.
