Abstract

In this paper, the results of experiment that using YAG laser and CO2 laser to weld 6009 Aluminum alloys are investigated. The experimental results show that the weld depth and area using CO2 laser are both larger than using YAG laser under the condition of the same power and the same welding speed. The reasons are analyzed through the aspects of absorption, beam quality, focal depth and plasma. The absorption of materials to YAG laser is higher than that of CO2 laser, but the CO2 laser has high beam quality and focal depth. On the other hand, laser induced plasma strengthen the absorption of materials, so using CO2 laser can get good weld quality. These two kinds of laser processing system are compared at last in this paper.
