Selectarc TIG F77

This ER100S-1 wire rod is a low alloy wire specifically designed for Gas Tungsten Arc Welding (GTAW) of high-strength steels (Rm > 700 MPa). It contains Nickel and Molybdenum for improved weld properties and offers good impact strength, even at low temperatures down to -50°C. It is commonly used in demanding applications within the chemical, petrochemical, and offshore industries, as well as for industrial machinery construction and crane fabrication. The wire’s composition is carefully controlled to ensure optimal performance.

This TIG F77 wire is ideal for welding high-strength steels, particularly those used in chemically aggressive environments, offshore structures, and heavy machinery. It’s suitable for applications requiring robust welds capable of withstanding significant loads and temperature variations. The recommended welding parameters, including shielding gas flow rates and preheating temperatures, are provided for optimal results. Typical applications include joining S460, S500, S550, S620 and S690 steels.
