Study of thermo mechanical charcterisation of tool geometries on friction stir welding
A numerical model is developed to predict the material deformations and temperature histories in the friction stir welding (FSW) process. Based on the numerical ananlysis, the effects of the welding parameters on material deformation and temperatures are investigated for plain cylindrical and drill tool geometries. A numerical result predicts that the temperature can be increased with the increase of the rotating speed on the FSW process. In the same way the increase in the weld speed can also lead to the tangible increase of the input power.
