SMAW
Type Basic

A nickel-cored electrode for welding normal grades of cast iron. The weld metal is soft and easily machinable. Deposition is performed on cold or slightly preheated material. The electrode is suitable for joining cast iron for the rectification of casting and the repair of broken parts.
