Welding Consumables and Process for Nuclear Power Plants
2018-08-23        |        【print

The development of high-performance welding consumables, weldability evaluation for newly developed nuclear material and the controlling of large welding structure deformation are carried out based on the manufacturing requirements for key welding structure in nuclear power plants. The microstructure evolutions and mechanical properties of heat affected zones (HAZs) are investigated by the numerical simulation and thermal-mechanical physical simulation to optimize the chemical composition of nuclear structural materials. The effects of micro-alloy elements on metallurgical defects, microstructures and mechanical properties of weld metal are studied to develop the high-performance welding consumables.
