Abstract
Ni201 is welded by manual argon tungsten arc welding,and ERNi-1 wire with the same chemical composition and the same strength grade as that of Ni201 is selected as the welding material.The physical properties of Ni201 are characterized by low thermal conductivity,high expansion coefficient and poor weld fluid,use large V-shaped groove,groove angle of 70° in the butt welding.In the welding process,adopt small welding line energy and short arc welding,layer temperature is less than 100 ℃.After welding,a series of tests have been carried out,which mainly include nondestructive testing,mechanical property testing and micro metallographic examination.The results show that all kinds of performance indexes meet the requirements of the standard with reasonable welding technology.关键词
