Notes:
In this particular work, the moving Gauss heat source model based on the gas tungstenarc welding and a new heat source model based on the laser-TIG hybrid welding were developed bythe finite element analysis according to the physical characteristic of the TIG welding and thelaser-TIG hybrid welding, Taking into account the advice of parameter modification, the modelingwas respectively carried out by the single TIG and the laser-TIG hybrid welding for AZ31Bmagnesium alloy. The welding temperature field and the weld cross-section geometry weresimulated separately with regard to dependence on the single TIG and the laser-TIG hybrid welding.Comparing the experimentally measured value with simulated value of the weld section geometry,the simulated and the experimentally determined weld section geometry by the single TIG weldingand the hybrid welding showed a good agreement, at the same time, the microstructures of the jointwere also discussed respectively
