AWS 5.18 ER70S-6 carbon steel solid welding wire

 

APPLICATION:

 

    This type ER70S-6 welding wire is applicable for single pass and multi-pass welding of carbon steel and 480 MPa grade Carbon 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 it is applicable for high-speed welding of sheets and pipeline steel.

 

 

FEATURES:

 

     CO2 gas-shielded copper-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. Smooth and shiny surface makes wire feeding stable.
