F 70S- G
AWS: SFA 5.18 ER70S-G
EN ISO CODE:
F 70S-G is a copper coated mild steel wire for GTAW. Suitable for welding of mild steel, low carbon steel and other structural steels of tensile strength up to 560 MPa. The wire burns with smooth arc. It is designed for welding of low and medium carbon steels like; SA-36, A/B/C/D grades of SA-283, A/B/C grades of SA-285, A/B grades of SA-414, etc.
