OK Autrod 12.20 is a copper-coated SAW welding wire for submerged arc and electroslag welding of medium- and high-strength structural steel. The wire offers excellent resistance to porosity, even at higher welding speeds, and delivers reliable welding results when used with suitable ESAB welding fluxes. It is typically used with the fluxes OK Flux 10.71, OK Flux 10.72, OK Flux 10.81 and OK Flux 10.83.
OK Autrod 12.20 is used for submerged arc and electroslag welding of medium- and high-strength structural steel in general structural work, pressure vessels and shipbuilding. The wire is designed for high productivity, consistent weld quality and reliable performance.
