ABSTRACT

15NiCuMoNb5-6-4 steel is Cu-Ni-Mo alloy; it has been widely used in power station industry such as boiler steam drum and pipes of the water supply system. Welding of 15NiCuMoNb5-6-4 thickness pipes is needed in the pressure pipes installation. The pipe system works under the condition of high pressure and temperature, in addition to the inner surface of pipes will be overlaid the stainless steel that helps the pipes to resist corrosion. Thus, the welding procedure becomes the key point for the installation quality-control. By using GTAW and SMAW method, the proper welding procedure is carried out, and welding procedure qualification test has been passed and metallographic microstructures analyses of welding joints are conducted. The results show that this procedure can ensure the mechanical property and corrosion resistant performance of weld joints.
