    Abstract: Electric arc overlay welding, often called arc cladding, on a metallic backing which in many cases will be a steel backing. A barrier strip rests on the backing and a strip electrode spaced from the backing arcs to the barrier strip. The barrier strip or the strip electrode made by powder metallurgy has a metal oxide such as iron oxide included in it which oxidizes carbon picked up from the metal backing.
