Selectarc FCW 77 M

This metal cored wire is specifically designed for welding high strength steels, utilizing a Nickel, Chromium and Molybdenum alloy composition combined with Ar + CO2 shielding gas. It exhibits exceptional mechanical properties at low temperatures (-60°C), ensuring robust welds even in challenging environments. It delivers good weldability, excellent bead appearance, and minimizes spatter losses. This product is suitable for demanding applications requiring high strength and low-temperature performance.

This wire is primarily used in crane construction, the fabrication of vessels and apparatus, and applications involving high-strength steels such as EN-Designations S550Q-S690Q, S550QL-S690QL, P550Q-P690Q, P550QL-P690QL, ASTM A 514 Gr. F, H, Q; A 709 Gr. 100 Type B, E, F, H, Q; and A 709 Gr. HPS 100W. Welding parameters are optimized for FCAW mode using a wire diameter of 1.0-1.6mm with an Ar/CO2 shielding gas flow rate of 12-15 l/min and a welding current ranging from 160-270A.
