308LSi is a G 19 9 LSi/ER 308LSi type solid TIG welding rod, supplied precision layer wound, depositing a low C-19Cr9Ni weld metal. Suitable for use with Ar+2%O2 or Ar+0.5…5%CO2 mixed shielding gases.
308LSi is used for welding 304 and 304L grade stainless steel. The weld metal provides good corrosion resistance to intergranular attacks from a range of liquid media. It is used for a wide range of applications including pipework and plate fabrication, vessel production, etc.
The low carbon reduces the propensity to intergranular carbide precipitation, which increases the resistance to intergranular corrosion without the use of stabilizers. The increased silicon content results in increased weld pool fluidity to give a smooth deposit appearance.
