Resistance welding is still widely used in carbody production. The character of the measurements demonstrated here is to detect the spot welds quality by regarding the dynamic strain properties of the spot welding gun during the welding process. With this setup an online diagnosis and simultaneously working quality supervision and parameter regulation is possible. As the quality of each single spot weld can be documented online the whole system has a forseeable future in the automotive sector.
