AWS ER80S-G Welding Wire

1. Description

AWS ER80S-G Welding Wire is a high quality solid gas shielded welding wire, welding wire containing the right amount of alloy elements, with rich argon (80%Ar+20%CO2) gas is used, the weld has excellent low-temperature impact toughness and CTOD, NDT. S and P content in the wire control strictlyand it has good cracking resistance.

2. Application

AWS ER80S-G welding wire is suitable for welding medium and thick steel plate for marine engineering structures with yield strength of 460MPa, or for welding of pressure vessel, bridge and steel structure steel plate of corresponding grade.
