BOHLER SAW WIRE & FLUXES

Submerged arc welding (SAW)

Submerged arc welding (SAW) uses a metallic filler metal (wire) and a non-metallic consumable, the welding flux. The welding flux has a significant effect on the weld appearance and slag detach-ability, as a result of the melting characteristics and various physical properties such as viscosity, surface tension, density, thermal expansion and electrical conductivity. The flux also affects the chemical composition of the weld metal and its mechanical properties, due to its metallurgical action.
