摘　　要：通过建立高斯热源模型,运用Ansys软件分析球罐对接接头焊接应力,发现应力最大值出现在余高与母材表面交界处的熔合线附近,这为消除球罐焊接残余应力提供了有力的帮助,同时对其他类型压力容器焊接应力的分析也有着积极的意义。The security of spherical tank is very important, so it is significant to analyze its welding stress.In this paper, a Gauss heat source model is set up based on ANSYS software.The welding stress of spherical tank butt joint is discussed with this model.The maximum stress appears near the fusion line of intersection of the weld reinforcement and the surface of parent metal.This study not only provides powerful help for eliminating welding residual stress, but also has positive significance for the welding stress analysis of other types of pressure vessels.
