基于CFD的活性TIG焊气路流场数值分析
Numerical Analysis of Gas Flow Field in Active TIG Welding Based on CFD
摘要
Abstract
The influence of different gas path structures on the gas flow characteristics of active tungsten argon arc welding was studied by CFD numerical analysis technology.Different gas path models of welding torch are created through modeling software,and the pressure field,velocity field and particle flow trajectory of gas basin of TIG wel-ding are numerically analyzed by using ANSYS fluent simulation software and DPM model.The results show that,the positive V-shaped gas path structure has a maximum pressure of 923 MPa and a speed of 44.4 m/s,which is the most suitable gas path form for welding among the three structures.At the same time,there is no particle deposition in the positive V-shaped gas path structure under DPM model,which is the best gas path structure to prevent parti-cle deposition among the three structures.It reveals some reasons for the blockage of the gas path of the active TIG welding gun and provides theoretical support for the improvement and optimization of the active TIG welding gun.关键词
