摘 要：Based on the three-dimensional model of TIG weld pool established,the effect of the arc force on liquid surface was investigated.The simulation was carried out with finite elements software Surface Evolver.The influence of the arc force on the weld pool shape was also studied.According to the results,the variation of the weld shape and the parameters with different arc force strength was obtained.Compared with the back weld pool,the top weld pool was influenced more strongly by the arc force.These results provide an effective basis for further study of the TIG weld pool.
