Nut & Stud Projection Welding Electrodes
Stud Electrodes
Tuffaloy stud electrode tips are for projection welding screws, bolts or pins, whether they pass through the sheet or are to be attached directly to its face.Nut Electrodes
Tuffaloy projection welding nut electrodes are designed for either self-piloted or non-piloted nuts. The pilots of the non-piloted-nut electrodes are spring-loaded so they can’t interfere with the contacting of nut and sheet under welding pressure.
