Zr–Nb alloys are used in the nuclear and chemical industries, in which the welding of an end cap to a fuel rod is a critical issue in manufacturing processes. To identify the optimal process parameters for achieving good-quality welds, it is necessary to investigate the thermal environment in the fusion and heat-affected zones. A three-dimensional computational fluid dynamics analysis is performed...
In recent years use of Zr-Nb alloys has increased in nuclear and chemical industry due to its corrosion resistance and enhanced strength compared to tin based ones. Welding of zirconium alloys is one of the most critical manufacturing processes for nuclear assembly production. To select suitable welding parameters to achieve quality weld, understanding of temperature and velocity fields during process...
