Welding Position

Characteristics
ER316L is designed for welding austenitic stainless steel type 17Cr 12Ni 2.5Mo or similar, where high resistance to general and inter crystalline corrosion is required.

Procedures
Mig welding can be performed as short, spray or pulsed arc. Short arc is preferably used for thin gauges, both for horizontal and positional welding. Shielding gas recommendations: Ar + 2% O2 or Ar 2-3% CO2. The addition of O2 or CO2 provides good arc stability. Welding can also be performed using an addition of 30% helium (He) which will also increase the energy of the arc. The fluidity is hereby improved and the weld is generally wider. The welding speed can therefore be increased. Addition of He will increase the blackening slightly. Gas flow rate: 12-16 l/min.
