Characteristics
ISOARC ER308L 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 stabilised steels.ER308LSi has enhanced silicon contant(0.85%) which improves the fluidity of the melt pool with a minimum of spatter and porosity.

Procedures
Welding is performed using direct current negative polarity (DC-). Welding can also be performed using pulsed current, which can be advantageous when welding in positions and for the welding of thin gauges. Shielding gas recommendations: the most frequently used shielding gas is pure argon (Ar) with a gas flow of 6-8 l/min. Addition of about 30% helium (He) or 1-5% hydrogen (H2) will increase the energy of the arc. This will give a wider weld and a better fluidity of the melt pool.
