SMAW
Type Basic

An electrode of the nickel-iron type for welding normal grades of cast iron and for joining them to steel. The electrode has very good current-carrying capacity. The electrode produces a weld metal stronger and more resistant to solidification cracking than that of the nickel electrode type.
