Resistance welding is a highly productive joining technology widely applied in automotive, electrical and electronics, and other metal processing industry. The process variants of resistance welding include spot welding, projection welding, seam welding, butt welding and micro resistance welding.

Due to the fact that many dynamic and interacting parameters are involved in the resistance welding processes, it is a huge task to setup and optimize the production lines applying resistance welding and often difficult to solve welding problems.

Many companies rely on resistance welding but want to get rid of the tedious and costly manual weldability tests.
More and more industry leaders have turned to simulations and optimizations with SORPAS®
to save costs, reduce time-to-market and improve weld quality.
