针对0Cr18Ni10Ti不锈钢放射源源壳钨极氩弧焊（TIG）焊接过程，采用ANSYS有限元软件对焊接温度场进行数值模拟分析，建立了非稳态 T IG焊接熔池形态的数值分析模型，分析中引入了热焓和表面分布高斯电弧热源模型，初步计算了焊接电流和焊接速度对焊接温度场分布的影响。通过比较焊缝有效熔深的测量结果和计算结果，验证了所建模型的正确性和可靠性。以计算结果为基础，对焊接工艺参数进行优化，建立了0Cr18Ni10Ti不锈钢放射源源壳的焊接工艺路线。

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 .
