Stud welding allows metal fasteners such as weld studs, weld pins and tapped studs, to be welded onto another metal object using an arc at lightning speed. An arc is produced between the end of the stud and the surface of the workpiece, melting both parts. The stud is then forged into the molten pool. The material solidifies and the stud is welded. The weld is uniform and has complete fusion across the flange. As the whole surface of the weld stud is joined with the workpiece, the resulting weld joint is stronger than the stud or parent material.
Since no holes are punched in the sheet, the workpiece is not weakened and corrosion problems are minimized. When welding the stud, access is only required from one side which means that component handling is considerably facilitated, especially as regards establishing an earth connection.
This absolutely leakproof, hole-free and decorative joining technique is used in many everyday objects and facilitates their handling. Be it coffee machines, cooking pots, flat irons, steam cookers or even in vehicles and roofing – many things would be impossible without stud welding.
With the development of the patented "SRM Technology®" procedure (patent no. 10 2004 051 389) it has even been possible to replace many areas of glueing, riveting, punching and drilling.
