Impact Welding

Studies on electromagnetic impact welding between similar or dissimilar flat sheet metals using the flat one turn coil have been recently achieved. In this study, three dimensional electromagnetic-mechanical coupled numerical simulations are performed for the electromagnetic impact welding of aluminum alloy sheets with flat rectangular one turn coil. The deformation behavior during impact welding was examined. The effect of process parameters such as charge voltage, standoff distance and gap distance were investigated.

6016 Aluminum Alloy

In order to realize numerical simulation of warm forming and reasonably establish the warm formation process parameters for 6016 aluminum alloy, we study the forging process of 6016 aluminum alloy with warm compression experiments on the Gleele-1500 thermal simulation testing machine, and research the deformation flow stress behavior of the aluminum alloy sheet at different temperatures , strain rate under the warm forming. The results show that the deformation temperature and strain rate have significant influence on flow stress of 6016 aluminum alloy sheet, that is, the alloy is a temperature and strain rate sensitive materials, and the flow stress increases with the increase of strain rate and decreases with the increase of deformation temperature. The deformation constitutive equation of 6016 aluminum alloy is got by multiple linear regression analysis. The constitutive equation is consistent with the experimental curves rather well, which confirms the accuracy of the constitutive equation.
