Product DescriptionER70S-6 Gas-Shielded Solid Welding WireER70S-6 is a 500 MPa grade carbon steel solid welding wire, classified under AWS A5.18 ER70S-6, GB/T 8110 ER50-6, and EN ISO 14341-A-G 42 4 C1/M21 3Si1. It is designed for gas metal arc welding (GMAW) of carbon steels and low-alloy steels of corresponding strength grades.This welding wire delivers outstanding performance across a wide range of industries, including engineering machinery, shipbuilding, vehicle manufacturing, petrochemical facilities, and structural fabrication. When used with CO2 or 80% Ar + 20% CO2 shielding gas, ER70S-6 exhibits minimal spatter, a smooth and attractive weld bead appearance, high deposition efficiency, and low porosity sensitivity. It supports all-position welding, providing excellent versatility for complex fabrication projects.The chemical composition of ER70S-6 is optimized for superior weld quality. Typical values include 0.08% carbon, 1.50% manganese, and 0.89% silicon, which enhance deoxidation and improve wetting characteristics. The deposited metal meets or exceeds standard mechanical requirements, with typical tensile strength of 560 MPa (≥500 MPa), yield strength of 450 MPa (≥420 MPa), elongation of 26% (≥22%), and Charpy V-notch impact toughness of 108 J at -30°C (≥27 J), demonstrating excellent low-temperature performance.Before welding, remove rust, grease, moisture, and other impurities from the base metal. Welding parameters directly affect the mechanical properties of the weld joint; more critical structures should use lower heat input (line energy). Reference current ranges from 50–180 A for 0.8 mm diameter wire up to 120–500 A for 1.6 mm diameter wire.| Parameter | Condition / Element | Standard Requirement | Typical Value |
