SAW fluxes

Submerged arc welding (SAW) uses a metallic filler metal (wire) and a non-metallic consumable, the welding flux. Böhler Welding offers a vast range of filler materials for submerged arc welding.
SAW flux Böhler Welding

The product range comprises over 120 wire/flux combinations covering non-alloyed, weather resisting, high strength, low-temperature and creep resistant steel, all types of stainless steel, as well as nickel-base alloys. All over the world, these are applied in demanding industrial segments, such as power generation, the process and chemical industries, up and downstream offshore fabrication, pipe mills, the nuclear industry, wind tower production and civil engineering. 

The welding flux has a significant effect on the weld appearance and slag detachability, 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.
