Description

- 10 - ABSTRACT : The invention relates to a welding electrode with smooth surface for gas shielded arc welding, comprising a steel substrate provided with a thin, ferrous oxide containing covering layer. This covering layer has a thickness of less than 500 A and the structure of a ferric oxide gel comprising trivalent Fe-cations surrounded by oxygen containing anions, which anion-surrounded cations are amorphously bound in an aqueous gel-like network. A method is also described of producing this electrode and of using it in an arc-welding process.
