NOVOFIL SG3
MIG/MAG welding wire for mild steels
MIG/MAGG4Si1 · ER70S-6
Description
NOVOFIL SG3 is a copper coated gas metal arc welding wire in 15 kg spools or 250 kg drums. It is particularly designed for semi-automatic and full-automatic GMAW applications.
NOVOFIL SG3 is suitable for GMA welding of un-alloyed structural steels with a tensile strength up to 540 N/mm², ship plates and fine-grained C-Mn steels. It gives high-strength weld metal at working temperatures varying between −50 and 450 °C. It contains higher Si and Mn than SG2 welding wire. Increased silicon improves wettability.
100% CO₂ or 80% Ar + 20% CO₂ are used for gas shielding.
