What is cladding overlay?
Cladding overlay is a welding process that metal with high performance of anti corrosion, wear resistance property is cladded on the base metal. A classic example is to clad stainless steel or Nickel based alloy on the carbon steel which shall be anti corrosion while cost reduces significantly comparing to pure stainless steel or Nickel based alloy.
