Welding Position

Characteristics
ER308LSi is designed for welding austenitic stainless steel type 19 Cr 10 Ni or similar. The filler metal is also suitable for welding titanium and niobium stabilized steels, E.G. ASTM 321 and ASTM 347, in cases where the construction will be operating at temperatures not exceeding 400deg C.

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 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: 12-16l/mm.
