General description:

NST MIG 308LSi is a low-carbon, solid MIG/MAG wire for welding of corrosion resistant materials such as
AISI 304, EN 1.4301, EN 1.4307 etc. Normally, mixed gas Argon/CO2 or Argon/O2 are used
as the shielding gas. This ensures a user friendly, stable welding arc with less spatter, good visual bead appearance and smooth transition to the parent material. The wire can be used both with or without Pulsesyncing. It can also be used for welding of Nb and Ti-stabilized materials (i.e. ASTM 321) when operating temperatures does not exceed 400°C. At higher operating temperatures, a Nb-stabilized welding wire is used. ”Purity” is the keyword when welding high alloyed materials. Impurities in the weld, will cause porosity. Inter-pass temperature should not exceed 150°C. Heat input should not exceed <2.0kJ/mm. The weld metal will have an Austenitic structure with a low portion of Ferrite (typically 5-9% ferrite).
