Spot Welding Copper
Spot Welding Copper material was developed as a result of systematic research conducted on rapid electrode wear in CRM 16. Compared to standard Cu-Cr-Zr, this alloy possesses additional properties due to the longitudinal fibers in its structure. Since this internal structure would deteriorate under a new heat treatment, forming must be carried out in the cold state.
Thanks to this special structure, the alloy achieves better cooling and higher hardness, allowing electrodes, clamp arms, and electrode holders to reach a significantly longer service life.
With this material, it is possible to weld unalloyed steel, all types of coated sheet metal, and stainless alloys in the most ideal way.
In spot welding machines, having all current-carrying parts made of copper ensures higher-quality welding at lower current levels and extends the lifespan of the electrodes used. We strongly recommend replacing the brass current-carrying components in your machine with copper.
