Weld cladding is a process of depositing thick layer of corrosion resistant material usually over carbon steel plates to improve its corrosion resistance properties and main problem faced in stainless steel cladding is 4he selection of process parameters for achieving the required clad bead geometry and its shape relationships Different categories of stainless steels are employed as the cladding material However, mechanical and corrosion resistant properties of cladded components depend on the clad bead geometry Therefore, it is essential to study the effect of process parameters on the bead geometry to enable effective control of these parameters Iron - aluminum-based weld cladding is also used as corrosion resistant coatings for boiler tubes in coal-fired power plants Although these alloys have excellent high-temperature corrosion resistance, Fe-Al weld cladding is susceptible to hydrogen embrittlement cracking at elevated aluminum concentrations Addition of chromium to iron aluminum alloys have been found to improve corrosion resistance, and could potentially increase the service life of the coating In this paper a brief review on this technique is presented.
