Validation of SORPAS® Simulations

Many factors influence the simulation results. In order to minimize the amount of work that users have to do to verify the highly dynamically coupled numerical models and their interactions with the input conditions, we have already made a lot of verifications and validations of all models with lab tests and user feedback. Many numerical … Continue reading

Can I use an absolutely flat tip design for the electrode?

Absolute flat tip of electrode does not exist in reality. Even if they made the electrode with absolute flat tip by design, after just one weld, the tip face is deformed to have a natural curvature with a radius of R=50mm to R=100mm approximately. The ISO Standard electrode forms are mostly with tip face curvature … Continue reading

Electrode degradation

Electrode degradation is one of the common problems in the welding industry. It decreases the nugget size due to reduced current density at the weld interface and reduced conductivity of the electrode tip. 1. Mechanisms of electrode degradation High current and pressure are key characteristics in the resistance welding process. Though they are necessary to … Continue reading
