Abstract
Aiming at tungsten inert gas (TIG) for 0Cr18Ni10Ti stainless steel cladding for radioactive source ,the numerical calculation of welding pool temperature field was carried out through adopting ANSYS software .The numerical model of non‐steady TIG welding pool shape was established ,the heat enthalpy and Gaussian electric arc heat source model of surface distribution were introduced ,and the effects of welding current and welding speed to temperature field distribution were calculated . Comparing the experimental data and the calculation results under different welding currents and speeds ,the reliability and correctness of the model were proved .The welding techno‐logical parameters of 0Cr18Ni10Ti stainless steel were optimized based on the calcula‐tion results and the welding procedure was established .关键词
