Laser Wobble Welding Process: A Review on Metallurgical, Mechanical, and Geometrical Characteristics and Defects

The laser wobble welding process has emerged as a novel welding technique designed to overcome the limitations of the conventional laser welding process. By introducing laser beam wobble on the workpiece during the welding process, this method enhances noticeable welding characteristics and effectively mitigates welding defects. Despite its significant importance, there remains a noticeable lack of comprehensive study that thoroughly explores the various characteristics of this technology. This study aims to bridge that gap by considering and analyzing recent studies about the laser wobble welding process, providing a holistic investigation of its characteristics and advantages in comparison to the conventional laser welding process. Furthermore, the study systematically examines laser wobble welding from four crucial perspectives: 1- Metallurgical, 2- Geometrical, 3- Mechanical characteristics, and 4- Defect. Each perspective is meticulously investigated and contrasted with those of the conventional laser welding process. The results of these studies unequivocally demonstrate the advantages of laser wobble welding over the traditional method. The findings highlight the improved weld quality and enhanced mechanical characteristics achieved through this innovative approach. In addition to the above analysis, this study also reviews prior research conducted in the field of laser wobble welding. By examining previous studies, the optimal range of power, frequency, and welding speed required to optimize the three critical aspects of the laser wobble welding process is established. In conclusion, this study, with a review of previous studies, provides valuable insights into the laser wobble welding process, shedding light on its potential to revolutionize the welding industry.
