NST MIG 316LSi

NST MIG 316LSi is a solid, MIG/MAG wire for welding of corrosion resistant materials such as AISI 316, EN 14401, EN 14404 etc. Normally Argon/CO2 or Argon/O2 mix 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 Pulse-syncing. It can also be used for welding of Nb- and Ti-stabilized materials (i.e. ASTM 316Ti) when operating temperature does not exceed 400°C. In higher operating temperature a Nb-stabilized welding wire should be 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. Recommended heat input should be low: <2.0kJ/mm, typically between 0.5-2.0 kJ/mm. The wire gives an Austenitic structure with very low Ferrite (typically 5-9%).
