Research on Influence Factors on Welding Residual Stress in Ball-Pipe Joints
摘要
Abstract
The magnitude and the distribution of the welding residual stress of such joints were researched with FEM method considering some different influence factors, and welding residual stress near the ball will reduce along with the increase of the thickness and diameter of the ball. And the welding residual Von-Misses stress and Z component stress will increase with the pipe diameter enlargement.关键词
