improper welding parameters or technological conditions are used[7-10], and such defects as groove, cavity and kissing bond have significant influence on the mechanical properties of the joints[11-13... welding. Based on the previous experimental results, the initial joints with groove defect and the good-quality repair joints can be produced by using the technological parameters listed in Table 2......
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......
