Description
Electrode with special coating and pure copper core.
Special electrode for welding of copper base alloys. It has an excellent electrical conductivity. It is specific for welding of electrolytic cells and components for steel plants. Phosphorus and silicon act primarily as deoxidizers, the other elements improve ease of welding and the properties of the final weldment. Preheating, 200°C to 500°C, is desirable on most work especially on thick base metal. Also suitable for weld overlays on steel component. Not suitable for stainless steels because Cr pick-up cause embrittlement.
