ER110S-G Welding Wire: High Impact Strength at Low Temperatures for Pipelines
ER110S-G Welding Wire For pressure vessels, construction machinery, and hoisting machinery
Specification:
1.ER110S-G is a copper coated wire containing NiCrMo for single pass or multipass welding of low alloy steels. Designed for welding high yield strength steels with a minimum tensile strength of 770 MPa. Excellent impact strength at low temperatures down to -40°C.
2. It is a kind of high strength gas-shielded welding wire. The mixed gas Ar+20% CO2 can be used as shielding gas. It has soft arc,
stable burning and low spatters. The bead has higher impact toughness.
Purpose:
Suitable for welding high strength structures with tensile strength of 790MPa. It can be used for welding some key structures, such as pressure vessels, construction machinery, and hoisting machinery.
