The microstructure of the weld influences its quality, in which the grain size is one of the most important parameters affecting the mechanical properties of the weld. To change the grain size, the cooling process of the weld zone must be carefully controlled. Customarily, the weld zone is cooled down without post-treatment after the welding process, so the microstructure of the weld is similar to that of the casting. In this study, ultrasonic vibrations are used in the welding process from the beginning of the welding process until the part is completely cooled. Using the ultrasonic waves with frequency of 20kHz, power of 1500W, the researchers analyzed the weld microstructure, comparing the welds with and without ultrasonic vibrations. The results show that when ultrasonic vibrations are utilized, the grain size is changed and the mechanical properties are significantly improved.
