The Ideal Solution for Resistance Welding Coated Steels

The introduction of galvanised and high-strength steels, as well as a variety of newly developed coatings in automotive manufacturing have created new challenges for the resistance welding industry.

Zinc, higher strength steels, and other coatings can have adverse effects on the performance and life of cap welding electrodes that lead to premature wear and tear, sticking and increased dressing frequency in order to maintain quality welds. As a result, traditional welding with chrome and/or chrome zirconium alloy electrodes has become inefficient and costly.

Luvata’s resistance-welding electrodes have been designed to overcome these challenges and provide the ideal solution for demanding welding conditions.

In today's resistance welding market, cap electrodes are manufactured from four materials: AL2O3, CrCu, CrCuZr and CuZr.
