Heat-resisting Steel Electrode AWS E7015-A1
Round Solid Rod / steel electrode is a kind of heat resistant steel welding electrode, which is applied to weld the covering of the boiler pipes (e.g.15Mo) after argon arc render with working temperature below 510°C. The solid rod can also be apply to weld general high strength low alloy steel.welding of boiler pipe line, working temperature of which is below 510oC, and also suitable for that of normal low alloy hing strength steel .
