Paper Title:
Gas Tungsten Arc Welding and Hybrid Laser-TIG Welding Temperature Field Analysis of AZ31B Magnesium Alloy
  Abstract

In this particular work, the moving Gauss heat source model based on the gas tungsten arc welding and a new heat source model based on the laser-TIG hybrid welding were developed by the finite element analysis according to the physical characteristic of the TIG welding and the laser-TIG hybrid welding, Taking into account the advice of parameter modification, the modeling was respectively carried out by the single TIG and the laser-TIG hybrid welding for AZ31B magnesium alloy. The welding temperature field and the weld cross-section geometry were simulated 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 welding and the hybrid welding showed a good agreement, at the same time, the microstructures of the joint were also discussed respectively.
