WELKO® – STUD WELDING

Stud welding with capacitor discharge has now been used successfully all over the world for many years. The welding process is carried out by the discharge of capacitors in a very short time of 1 – 3 ms (0.001 – 0.003 sec.) from the ignition tip of the welding element. The process has more than proved its value in vehicle construction, in sheet metal working and in decorative metal working.

CAPACITOR DISCHARGE STUD WELDING

The tip-ignition process enables studs, bushes and pins in sizes ranging from M3-M8 (M10), or from 3-8 mm diameter, to be welded on at lightning speed. It goes without saying that we also carry insulating nails, cupped-head pins and earthing tags in our range of products.
We carry an extensive selection of stud welding machines with the most modern technology, from welding guns to CNC stud welding systems in a variety of sizes and configurations.
