The Correct Stud for any Application

The welding elements or studs for aluminum stud welding with tip ignition are specified in DIN EN ISO 13918. Problem: At the DIN EN ISO 13918 there is no specification for aluminum studs for drawn-arc or short-cycle drawn-arc studs. Currently there is no international standard for welding elements for the drawn-arc processes.

The automotive and shipbuilding industries are regulatory exceptions. In the automobile industry, the technical rules (factory standards) of the manufacturers apply. The welding elements used are generally manufacturer-specific drawing parts. These studs are usually made of AlMg5 due to the high strength requirements. There are similar solutions in shipbuilding.
