以T型接头为例，着重对固有应变法进行研究，并运用正交试验法，对多道焊焊接顺序、焊接方向的影响因子进行优化设计，采用ANSYS软件通过一次性弹性计算得到焊接变形，以位移差为评价指标，得到最佳影响因子。结果表明：基于正交试验设计的固有应变法能够较准确地预测焊接变形，历时短，并且能体现焊接顺序、焊接方向对于焊接变形的影响。

Taking T-joint as an example , we focus on the study of inherent strain method and optimal design of the factors which influence the welding sequence and welding direction in orthogonal experiment design , get welding deformation through one-time elastic computation using ANSYS .Taking displacement difference as the e-valuating index , we get the best impact factors .The result shows inherent strain method based on orthogonal ex-periment design can accurately predict the welding deformation with short running time , and can reflect the influ-ence of welding sequence and direction on welding deformation .
