| Abstract: | We use FLUENT to conduct numerical simulation upon TIG welding pools.In the model,many factors are considered including liquid metal turbulence,latent heat of phase transformation,material thermo physical properties are the function of temperature.The calculated results show that the welding model can be developed easily by FLUENT and its graphics results can display the fluid flow and temperature distribution in welding pools clearly.It will help to guide and study about welding process. |
