Advances in Preparation and Welding Techniques of Stainless Steel Clad Plates
The stainless steel clad plates have the advantages of good corrosion resistance,low cost and high strength,compared with the traditional mild steel and stainless steel,the application of stainless steel clad plates extend the design service life of the structure,while reducing the whole life operation and main-tenance costs,showing a relatively high comprehensive price in the application of high corrosion-resistant grade structures.At present,stainless steel clad plates have been successfully applied to pressure vessels,railroad highway steel bridge panels and water conservancy and hydropower projects in many fields.The pa-per analyzed the research status of preparation and welding techniques of stainless steel clad plates,focu-sing on the vacuum rolling cladding method,explosion cladding method and explosion-rolling cladding method of the three mainstream preparation processes,the welding technique of clad plates were discussed comprehensively from the aspects of welding process,joint non-destructive testing and performance,effi-cient welding process and welding finite element simulation and so on,as well as the development trend of the preparation and welding technique of stainless steel clad plates.
