FIELD: electrical engineering; technological processes.
SUBSTANCE: invention relates to a coated rod electrode for arc welding. Portion of the electrode wire of the electrode containing Fe is coated with a coating agent. Gripped part of the electrode wire held by the electrode holder is coated with a coating layer containing a Ca compound. Ratio of area of coating layer to gripped part makes 20 % or more. Layer of said coating has thickness of 0.5–15 mcm and has surface roughness Ra of 1 mcm or less.
EFFECT: welding electrode for arc welding has excellent arc stability.
