Selectarc FCT 309L

This TIG cored wire, designated FCT 309L, is specifically formulated for root pass welding of 309L stainless steel and for joining dissimilar metals with stainless steel. The flux coating provides protection against atmospheric oxidation during the root pass, allowing for operation within a wide temperature range (-196°C to +400°C). It’s suitable for welding applications involving steel piping and petrochemicals. The wire offers robust mechanical properties, as detailed in its specifications, and is compatible with various stainless steel grades, including 309L, 304LN, and 309S.

This TIG cored wire is primarily intended for use in the root pass of TIG welding applications, particularly when joining dissimilar metals involving 309L stainless steel. Its protective slag coating safeguards the weld root from oxidation, making it ideal for pipelines and petrochemical environments. Welding parameters should be adjusted based on the specific base material and desired weld characteristics. Refer to the provided welding instructions for recommended current, voltage, and shielding gas settings.
