| Abstract Scope |
Magnetic pulse welding (MPW) technique combines high speed forming, impact and results in a partial weld at the collision zone of the accelerated flyer and the impacted target. Flyer, target and the acting coil can be positioned in different configurations resulting in different deformations of target and flyer accelerated by the magnetic pulse in the coil and thus different welds. The local effects for dissimilar metal joints of aluminum EN-AW-1050 and copper Cu-DHP are investigated for different configurations and impact energies by local micro tensile tests in thickness direction of the welded two metal sheets leading to the local weld strength distribution. For micro sample preparation, thin cross-sectional stripes (0.5 mm) are extracted from the contact parts of the sheets. The micro experiments are accompanied by micro structural analysis. These local microscopic testing and analysis results are correlated to integral macroscopic lap shear tests on the welds supported by simulations. |
