During welding, mill scale hinders the flow of the liquid weld pool, often causing an undesirable weld appearance or contour. Mill scale also can impede penetration into the base material and cause a lack of fusion and weld inclusions. The greater the thickness or severity of the mill scale, the more challenges there are in welding the material.
