FIller Metal Breakdown

SW-307 Cored

These wires are suitable for all position welding and has easier re-arcing, beautiful bead appearance and better slag removability. The operators benefit from a fast freezing slag system which assists them with good performance not only in flat and horizontal but also in all welding position. SW-307 cored is all position Flux Cored wire with a hot cracking resistant austenite weld metal. The tough weld metal has an excellent crack resistance, This wire is designed for welding dissimilar steels, 13Mn steels with Reduced weldability and for cladding carbon steels, can also be used As a buffer layer prior to hard surfacing.
