GEE GETIG 70S3 ER70S3 Mild Steel Copper Coated Welding Wire

GETIG ER70S3 Mild Steel Copper Coated Welding Wire GEE GETIG 70S3 / ER70S3 is a mild steel copper-coated welding wire designed for gas-protected welding applications. It is suitable for CO₂ gas protective welding and offers stable welding performance, good welding seams, reduced spatter, and excellent welding process properties. The wire is also suitable for welding high-tensile steel up to the 490 N/mm² grade, high-speed thin plate applications, and commonly used steel grades such as 35 and 45. Key Features GEE GETIG 70S3 ER70S3 classification Mild steel copper-coated welding wire Stable welding performance Good welding seam quality Less spatter Excellent welding process properties Suitable for high-speed thin plate welding Suitable for high-tensile steel applications Suitable for carbon steel tubes and plates Product Specifications Specification Details Brand GEE Limited Product Name GETIG 70S3 Product Type Mild Steel Copper Coated Welding Wire Identification GETIG 70S3 / ER70S3 Classification AWS A5.18: ER70S3 Coating Copper Coated Shielding Gas Pure Argon Tensile Strength (UTS) 480 MPa Min Yield Strength (YS) 400 MPa Min Elongation 22% Min CVN Impact Value ≥27 J at -30°C Standard Length 1000 mm Available Sizes 1.2 mm, 1.6 mm, 2.40 mm, 2.50 mm, 3.15 mm, 3.20 mm Packing per Packet 5 kg Packing per Box 20 kg (5 × 4) The classification, mechanical properties, shielding gas, and available packing sizes are specified in the GEE datasheet.
