Mig Welding Wire
ER310

Characteristics
ER310 is designed for welding high temperature steels such as ASTM 310S and similar.

Procedures
Mig welding of 310 materials is best performed using spray arc or pulsed arc . The weldability using short arc is somewhat limited and the welding of thin gauges (<3mm) and in-position is best performed using pulsed arc. Shielding gas recommendations: Ar or Ar + 30% He. The helium addition improves the fluidity and gives a slightly wider penetration. Helium increases the energy in the arc and the heat should therefore be kept at a lower level than when welding without helium to compensate for the higher temperature in the arc. Addition of the helium will increase the blackening slightly. Gas flow: 12-16 l/min.
