“…Other approaches to dissimilar material joining include impact welding, which can be initiated through vaporizing foil, magnetic pulses, and explosives. Vaporizing foil actuated welding (see the Thurston et al article in this issue 18 ) uses the energy pulse from a vaporizing conductive foil to collide a flyer material into an offset plate. This technique has proven effective for a wide variety of metal combinations, including copper-titanium, copper-steel, aluminum-copper, aluminum-magnesium, and titanium-steel.…”

“…In recent times, the utilisation of the vaporizing Foil Actuator has showcased its versatility as a tool for various metalworking applications, with one such application being impact welding of dissimilar materials. The process of vaporizing Foil Actuator Welding (VFAW) is representative of a high-velocity impact technique [11,12]. During this process, a flyer sheet is propelled towards the target sheet at impressive speeds ranging from 500 m s −1 to 800 m s −1 .…”

The composite structure of aluminium alloy and stainless steel provides a wide range of comprehensive advantages, encompassing properties such as lightweight, high strength, and corrosion resistance. These advantages make composite structure particularly suitable for various applications in industries such as transportation and chemicals. One innovative solid-phase welding technology that is well suited for joining dissimilar materials is vaporizing foil actuator welding. This technology allows for the welding of composite structures made of aluminium and stainless steel, despite the significant differences in physical and chemical properties. To enhance the vaporizing welding process, this paper proposes the introduction of an interlayer between the dissimilar materials. The interlayer consists of a third material that is added to bridge the gap between materials with differing hardness and plasticity. The main objective of introducing the interlayer is to minimise performance disparities and reduce the formation of intermetallic compounds at the interface. By examining the vaporizing foil actuator welding process of aluminium alloy and stainless steel with the interlayer, it aims to analyse the characteristics of the interface morphology. Additionally, this study investigates the energy conversion mechanism of the aluminium foil gasification process and explore the influence of the interlayer on the microstructure and mechanical properties of the interface between aluminium alloy and stainless-steel joints.

“…Vivek et al [1]). The majority of research so far focuses on welding through plastic deformation during impact with regard to both experimental [2] as well as modeling [3] findings. Similar to electromagnetic or electrohydraulic forming [4,5], a capacitor bank discharge is used to supply the process energy (Fig.…”

Electrically vaporizing foil actuators are employed as an innovative high speed sheet metal forming technology, which has the potential to lower tool costs. To reduce experimental try-outs, a predictive physics-based process design procedure is developed for the first time. It consists of a mathematical optimization utilizing numerical forming simulations followed by analytical computations for the forming-impulse generation through the rapid Joule heating of the foils. The proposed method is demonstrated for an exemplary steel sheet part. The resulting process design provides a part-specific impulse distribution, corresponding parallel actuator geometries, and the pulse generator’s charging energy, so that all process parameters are available before the first experiment. The experimental validation is then performed for the example part. Formed parts indicate that the introduced method yields a good starting point for actual testing, as it only requires adjustments in the form of a minor charging energy augmentation. This was expectable due to the conservative nature of the underlying modeling. The part geometry obtained with the most suitable charging energy is finally compared to the target geometry.
