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 the safe and clean welding of weld studs up to M16 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. Application of shielding gas instead of conventional ceramic ferrules protects the welding point from the atmosphere. Material: steel, stainless steel, heat-resistant steel and aluminium. For the first time it is optionally possible to weld nuts of the commercial type M5 – M12 on punched and non-punched sheet metals requiring only special stud holders for the hexagon nuts.
