Laser forming is a new flexible sheet metal forming process. By means of the theory of orthogonal experimental design method, design of experiment and optimization were carried out on thin aluminum-lithium alloy AA2090 sheet metal laser forming under the condition of water-cooling. And through the calculation and analysis of the experiments, the effect of the four process parameters related to the energy of laser beam on bending angle under the condition of water-cooling were ranked in order of laser power, number of scan, scan speed and beam diameter. Furthermore, the optimum process parameters were obtained, and experiment verifications were carried out.

Weld Porosity

The laser welding of Aluminum-Lithium alloy (Al-Li) alloy were conducted to investigate the weld porosity features in this paper. The results show that there are two kinds of weld porosity existing for laser welding Aluminum-Lithium alloy sheet. They are can be divided into metallurgical porosity and unstable keyhole porosity according to their different reason causing them. The mechanism of unstable keyhole porosity occurring was discussed according to the results of YAG laser welding processing. The methods how to reduce weld porosity for laser welding of Aluminum-Lithium alloy was also described.
