摘要
Abstract
Aimed at deformation problem of TC4 titanium alloy thin-wall pipe TIG welding, it adopted welding simulation software SYSWELD and double ellipsoid heat source model to establish a finite element model to simulate TIG welding course of TC4 thin-walled tube. Through three-dimensional laser scanning measure for welded specimen deformation, the temperature field after welding and welding deformation were analyzed. The results indicated that the welding deformation simulation result is consistent with test result;the validity of finite element model was verified.关键词
