MIG / MAG Wire (GMAW)
ES SG2 A5.18: ER70S-6 / EN 440: G3Si1
Description
Copper-coated, manganese-silicon-alloyed solid wire for the of non-alloy steels, such as general structural, pressure-vessel and ship steels, as well as fine-grained carbon-manga¬nese steels for the same purpose, with a mini¬mum yield strength of less than 420 MPa.
ES SG2 welded with pure CO2 as the shielding gas.
