Description
AWS ER70S-3 CO2 gas shielded welding wire is a kind of welding wire, also called mag/mig welding wire which is matched with CO2 gas or Arc gas in welding. It has strong resistance to surface scales and oil stains on the base metal. It has low blowhole sensitivity.
Application: Suitable for butt of fillet structures made of mild steel and 500MPa high tensile steel, in particular for high speed welding sheet steel.
Packing: 5kg/10kg/15kg/20kg/spool in carton, 250kg/ drum, 21.6MT -25.2MT per 1X20" FCL.
