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.
