The Impact

10mm thickness AZ31B magnesium alloy was used as the friction stir welding object in this study. Different welding joints were obtained by setting different friction stir welding parameters. Metallographic analysis and impact loading test were carried out on the joint area. The experiment results show that (i) when the rotational speed of the stirring head is 600rpm and the welding speed is 120mm/min, the microstructure of the joint has the characteristics of compactness, thinning, and large-area twinning, which is beneficial to improve the plasticity of the joint area; (ii) the impact load of the joint is the highest, but lower than that of the base material, which is 95.5% of the base material; (iii) the fracture of impact specimen presents ductile fracture.

Hardness Tests

The mechanical behavior of butt welds made on AZ31B magnesium alloy plates by solid-state friction stir welding (FSW) and gas tungsten arc welding (GTAW) is presented. Fatigue, tensile strength, and hardness tests were performed. Also, fractographic analyses of the weld microstructures were conducted. Tests results show that the fatigue performance of FSW joints was superior to that of conventional welding (GTAW).

The article is devoted to the one of the features of choosing the technical parameters of regime of friction stir welding. The tool tilt angle is the object of research. This parameter underlies the mechanism of the formation of welding joints. The methodology and the experiment’s results of determining the influence of the tool tilt angle from the power and thermal characteristics of the process of friction stir welding are presented in this work. Also there is a presentation of the results of the welded joints’ studies which were done by the non-destructive and destructive methods of control. The dependency of the tool tilt angle from the power and the temperature in the welding zone is defined on the basis of the received results.
