welding wire 70s-6 for mig welding
APPLICATION
Applicable for single pass and multi-pass welding of carbon steel and 500 MPa grade low alloy steel and is widely used in such fields as automobile industry, construction machinery manufacturing, ship building, metallurgical and mining equipment manufacturing, bridge building, petrochemical industry and pressure vessel manufacturing, etc. Also applicable for high-speed welding of sheets and pipeline steel.
FEATURES
CO2 gas-shielded flux coated welding wire has excellent welding technological property: the electric arc is stable with less spattering, the appearance of welded joint is nice with good crack resistance: it applies to all-position welding.
