Description
AWS ER70S-6 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: Used for welding all kinds of 500MPa structural steel parts and all kinds of 500MPa plates and pipes. It is widely used in marine containers, vehicles, ships and machines.
Packing: 1kg/5kg/10kg/15kg/20kg/spool in carton, 250kg/ drum, 21.6MT -25.2MT per 1X20" FCL.
