ABSTRACT:
Method and front-end fixture adapted for use with manually-operated electric stud welding guns, which permits the successful welding of a plurality of metal studs uniformly onto a workpiece. Various aspects of the invention provide for repeated accurate spacing of the studs as they are successively welded, for accurate alignment of a series of studs, and for each stud to be oriented in a disposition substantially perpendicular to the surface of the work piece. The preferred embodiments include a bracket mounted to a conventional welding gun, an alignment bushing mounted on the bracket forward of the chuck of the gun for contacting a previously-welded stud, and a footpiece mounted on the bracket rearward of the chuck.
