The patented stud welding process in the radial symmetrical magnetic field (patent no.: 10 2004 051 389) in conjunction with the innovative HZ-1 universal weld stud featuring a plane end face and centering tip enables the safe and clean welding of weld studs up to M16. In this process, the use of ceramic rings is no longer needed.

This procedure opens up whole new possibilities especially in automated stud welding plants and large-scale component production.

The stud is placed into contact with the workpiece and is raised. The arc is triggered.

Arc is guided in a spiral through the magnetic field and melts both join parts on their entire surface.

The stud is immersed in the very flat penetration zone and is inseparably connected.
