In this article, the weldability of dissimilar lap joints between 2 mm thick sheets of AA6022 aluminum (bottom) and AZ31 magnesium alloys (upper) was studied using a fiber laser with a wobbling scanner. The effects of laser beam wobbling parameters, laser power, traveling speed, and the presence of...
