Cladding is a welding procedure that puts weld metal on the surface of the work, as opposed to joining two pieces of material. Generally this is used for corrosion resistance or wear resistance and frequently a different aterial is used for the clad than for the base metal. Weld Overlay Cladding at Namdaran Petrogas Ind.
