Welding methods

Stud welding is one of the arc stud welding methods. The different methods are described in detail in DIN EN ISO 14555. The fastening elements for stud welding are described in DIN EN ISO 13918; the only applies to rotationally symmetrical components. At OBO BETTERMANN, these welding studs are created on state-of the-art multiple die presses through cold reduction. Decades of experience and continuous development of the manufacturing process guarantee the exceptional quality of OBO welding studs. In addition, there is a wealth of fastening elements for stud welding, which are not standardised, for example, the flat connector, also called an earthing connector. OBO BETTERMANN has been producing these punched parts at the highest level of precision for many years. Modern punching tools an presses quarantee a high standard of quality for the fastening elements, as is required for hight-quality welding.


The welding methods are split into two main groups, which prevail in practive, according to the application:


1. Capacitor discharge stud welding with tip ignition. There are two variants of this method: gap welding and contact welding.

Contact welding

2. Stud welding with arc ignition with the subgroup short arc ignition stud welding (short cycle).
