Paper Abstract

Laser welding of A5083 aluminum alloys with high power CO2 laser is experimental studied in this paper. The study shows that under determinated welding condition, an additional plasma control tube would achieve good plasma suppression, which results in good welding quality. The shielded gas flow acting on the keyhole in CO2 laser welding of A5083 aluminum alloy is numerical simulated by finite element method. From the ANSYS numerical simulation diagrams of the keyhole’s gas flow field, it can be seen that the additional plasma control tube would achieve good plasma suppression to maintain the keyhole.
