Frequency Pulse

The plate butt welding tests have been carried out to the 2219 high-strength aluminum alloy material by utilizing the self-development compound high frequency pulse TIG power source, whose results show that the mechanical properties of the welding seam may be effectively enhanced by adding the high frequency pulse energy. Therefore, a acoustic emission sensing system was established to acquire the transmission effect of the high frequency pulse arc energy during the welding process; moreover, the influence on the welding seam microstructures by the compound high frequency pulse energy has been studied. The results show the following effects: the porosity number at the both sides of the welding seam fusion line may be decreased significantly by adding the high frequency pulse energy; The analysis to the high frequency pulse action mechanism has been carried out according to the above conclusions to provide the technology theory base for improving and enhancing the aluminum alloy welding joint performances.

Stretching Process

The level and distribution of residual stresses have great impact on dimensional stability, while Vibratory Stress Relief (VSR) is an effective technology to relax or homogenize residual stresses. Experimental study on residual stresses distribution, residual strain energy and machining deformation of 7075 high-strength aluminum alloy thick plate under different aging process status shows that VSR can effectively decrease the amplitude and strain energy density, and enhance stability of dislocation structures and phase states in metal microscopic volume, then internal residual stresses are homogenized to enhance components’ anti-deformation capacity. In addition, the capability in maintaining dimensional stability from VSR is better than that from traditional mechanical stretching process
