The patented SRM stud welding process (patent no.: 10 2004 051 389), in conjunction with the innovative HZ-1 universal weld stud featuring a plane end face and centering tip (patent no.: 10 2006 016 553) enables welds at a sheet thickness to stud diameter ratio of 1:10 instead of 1:4 as previously. In this process, the use of ceramic rings is no longer needed.

The numerous advantages delivered by the SRM procedure open up whole new possibilities for application especially in automated stud welding plants and large-scale component production.
