AWS A5.18 ER70S-6 Welding Wire
ER70S-6 is a commonly used low-carbon manganese structural steel argon arc solid TIG welding wire or rod, specified in AWS A5.18. It has excellent resistance to base metal oxide scale and oil pollution, small porosity sensitivity, also offer good plasticity, toughness and crack resistance, especially low-temperature impact toughness. It has a wide application for manual tungsten argon arc welding of steel pipe and steel plate of low carbon and low alloy structural steels ASTM A105, A53 GRB, A516, A572 GR50, GR65, etc. in construction machinery, shipbuilding, vehicle manufacturing, petrochemical and other industries.
Welder metals is one of the leading manufacturers, suppliers, exporters, stockiest of steel MIG/TIG welding consumables such as wires, rods and electrodes. The C-Mn steel rods ER70S-6 wire or rod supplied by us are in strict accordance with AWS A5.18 and other equivalent standards. We provide not only the high-quality copper-coated ER70S-6 welding rods products but also no-copper coated as per the specifications of American, European and Chinese specifications.
Why I need non-copper-coated welding rods? The welding experiments show that the weld forming quality of the non-copper-coated wire is obviously better than that of copper-coated wire. Non copper coated wire in the welding process shows a series of advantages, such as less welding smoke, less welding spatter, good welding arc stability and weld forming, etc., is a kind of new products that is environmentally friendly and economical, has been widely used in mechanical processing, construction engineering, aerospace, bridge engineering, steel structure processing, etc., can be considered to be the development direction of solid wire.
