made of base metal plates, as shown in Fig. 1, was welded by variable polarity tungsten inert gas welding (VPTIG). The welding machine used in this study was a Miller Dynasty 700. The welding parameters..., and a TSL-2A arc high tester was used to measure the deflection of the specimen at intervals of 50 mm. A total of 11 deflection values were obtained along the edge of the plate in the welding direction......
of AZ61 magnesium alloys is investigated using a special CO2 laser experimental system. The effect of processing parameters including laser power, welding speed,and protection gas flow at the top.... Among them, laser power and welding speed are the two main parameters that determine the weld width and dimensions. The protect gas flow rate has a slight effect on the weld width, but it directly effects......
welding speed needs to be adopted in laser-beam welding of GH4169, and can achieve a well-shaped welding morphology and avoid the generation of microcracks [10,11]. Microcracks occur easily in gas tungsten arc welding, because the welds have mainly cast structures, which exhibit serious inhomogeneity in components and dendritic structures [12,13]. The characteristics of electron-beam welding......
