| Abstract: | In this review, the recent developments in laser welding of aluminum alloys are reported. The advantages of aluminum welding by laser and the general weld defects in laser welding of aluminum alloys are presented with an emphasis on the complexity and particularity of keyhole formation during the welding and the up-to-date development in keyhole research. It is pointed out that the most amazing aspect of laser welding lies in its high efficiency and deep penetration welding is a suitable case to demonstrate its advantages. To fulfill this task, however, the porosity defect caused by keyhole must be properly addressed. |
| Keywords: | laser welding aluminum alloy weld defect keyhole |
