: The thermo-elastic-plastic finite element method (FEM) is used to simulate the thermo-mechanical behavior of Al/steel tungsten inert gas (TIG) arc-assisted laser welding-brazing (A-LWB) butt joint... [5,9-13]. MENG et al [9] performed the calculation for the temperature distribution during the large spot laser assisted metal inert gas (MIG) welding-brazing and then revealed the auxiliary effect......

-consuming. CAO et al [18] and SHEN et al [19] observed that macropores were formed in laser beam and gas tungsten arc welding of the magnesium alloy AZ91. WAHBA et al [20] also reported that 10% pore area fraction was formed in laser welding of this alloy. SUN et al [21] investigated solidification cracking of the AZ91D alloy during gas tungsten arc welding. They suggested that hot cracking......
; where p is the atmosphere gas pressure; Ta is the temperature of the electric arc column; T0 is the ambient temperature; r is the arc radius; σ is the instantaneous arc conductance per unit volume; σ0 is a constant and α is a characteristic temperature for ionization of the gas, α= 1.601 4×104 K (for air at 1.013×105 Pa) [13]. Based on the above equations, the differential equation of the arc model......
of magnesium alloy can be realized using diffusion bonding, friction stir welding (FSW), electron beam welding (EBW), laser beam welding (LBW), activating flux tungsten inert gas (A-TIG) welding, laser-arc hybrid welding (LAHW) [2-7], filling wire is unavoidable in the welding of thick plates. Compared to other welding methods, metal inert gas (MIG) welding is a kind of high-efficiency wire filling......

are restricted by this welding technology and the practical application is limited for the high cost and productivity. Tungsten inert gas (TIG) welding, as an effective bonding technique, is characterized... with acetone to remove grease and polished with sand paper to remove oxides. The welding experiments were performed with a tungsten inert gas welding machine (YC-300WP5HGN). As shown in Figure 1......
