CD multi-pulse welding of welding nuts on 22MnB5 + AS150
Hans-Jürgen Rusch and Nicolas Stocks
The welding of welding nuts onto press-hardened steel with a coating of AlSi is extremely important! In body construction in particular, almost every part has functional elements. These elements are applied using the projection welding process. For years there have been international efforts to carry out this process safely and economically for very large quantities. The "combined pulse sequence" process developed by KAPKON will be presented, which makes unprecedented qualities possible, es-pecially by using the theory of capacitor discharge welding (CD welding).
