Nickel Alloys Ni-Alloy Surfacing 2'/4Cr-1 Mo Substrate Carbon Steel Substrate Strip Submerged Arc Shielded Metal Arc Postweld Heat Effect Interface Regions though relatively uniform mixing occurs in the bulk weld metal, complex micro-structures develop close to the fusion line where a gradient in composition be tween the base metal and the weld metalSurfacing of Metals: Meaning, Types and Selection | MetallurgyFor cladding, stainless steel or one of the nickel-base alloys are normally used though copper-base alloys, silver and lead are also used for some specific applications. Although the main advantage of cladding is the creation of low cost corrosion-resistant surface but it also combines a high strength material like low alloy steels for the backing with corrosion resistant material like stainless steel.Special Welding MaterialsSpecial Welding Materials. Hundreds kinds of special welding materials has been developed such as low alloy steel welding materials, molybdenum and chromium molybdenum steel welding materials, low temperature steel welding materials, stainless steel welding materialsNi or Ni alloy welding materials, strip surfacing materials, brazing materials and other products.
