ER70S-6 Welding Wires

Material designation: ER70S-6

Standard: ASME SFA-5.18 carbon copper welding wire and filler wire standard for gas shielded welding

Steel group: welding filler material

Notes:Suitable shielding gases: MAG-process 100% CO2, Ar +18 % CO2,CO2+ Ar + O2 (C1,M21,M22-M33 according to EN 439) ;TIG-process Ar (1 according to EN 439);

Application: Solid copper coated welding wire for welding in gas shielding atmospheres. Suitable for welding unalloyed steels with tensile straight below 530 N/mm2 like boiler plate, fine-grained steels, pipe steels, shipbuilding steels and cast steels. Unalloyed steels: DIN St 33 to St 60.2; Fine-grained steels: DIN StE 255 to StE 355,W StE 255 to W StE 355;Boiler and vessel plate: DIN HI,H II,17Mn4, 19Mn5;Pipe steels: DIN St 35 to St 52.4, E St E 210.7 to St E 360.7; Shipbuilding steels: DIN A,B, D,E;Cast steel: DIN GS 38 to GS 52.

Description: It belongs to copper-plated low-alloy steel gas shielded welding wire, using CO2 or rich argon as shielding gas for welding. It has excellent welding performance, stable arc combustion, less spatter, beautiful weld shape, low sensitivity of weld metal pores, good all-position welding process, suitable for a wide range of welding current.

Uses: Suitable for single-pass and multi-pass welding of carbon steel and 500MPa grade low-alloy steel (such as welding of vehicles, bridges, buildings, mechanical structures, etc.), and can also be used for high-speed welding of thin plates and tubes.

ER70S-6 is alloy welding wire steel. Mainly used for gas shielded welding. Gas shielded welding is arc welding that uses external gas as the arc medium and protects the arc and the welding area. Gas shielded solid welding is a high-quality, efficient and energy-saving welding method. It has been widely used in my country’s heavy machinery, construction machinery, ships, boilers, vehicles and other manufacturing industries. In recent years, my country’s gas shielded welding has developed rapidly, and the amount of gas shielded welding wire is increasing. The market demand for welding steel wire rod for processing gas shielded welding wire is rapidly increasing. ER70S-6 is a commonly used gas shielded welding wire variety abroad. The chemical composition is controlled according to the requirements of the American Welding Society standard AWSA5.18. The welding wire has better arc stability and higher weld performance during welding, and is widely used abroad.
