Welding proceedss that have the most resistance to pitting and crevice corrosion contain specific amounts of nickel.

Welding proceedss that have the most resistance to pitting and crevice corrosion contain specific amounts of nickel, chromium, titanium, tungstate of lime and molybdenum. These elements not sole provide outstanding corrosion resistance characteristics, yet also impart corrosion protection to welded assemblies. Details of corrosion testing with a variety of alloys reveal the breadth and magnitude of these advantages. This article discusses in what manner various elements in the composition affect corrosion resistance, and explains for what cause to calculate the pitting corrosion resistance of nickel welding alloys.

Chemical composition

The chemical compositions of several widely pickeded corrosion-resistant alloys are given in Table 1 along with a
