Submerged Arc Weld-Overlay
At Mill Mechanical we offer Submerged arc weld-overlay to rebuild out-of-tolerance work rolls used in the steelmaking process. We specialize in, but are not limited to 14”, 16” and 18” rolls. Our weld-overlay process is completely customized and our CNC manipulator can be dialed in to produce the exact requirements of our customers. We can adapt to various surface hardness specifications through welding wire selection and heat treatment in our 380ft ‘3’ furnace, as well complete the rolls with a machined finish.
