“…The conclusions indicated that a welding window for these two metals exists, but it is too narrow to obtain a nice bonding interface. Some other researchers have done work on Al-Steel plates by explosive welding, but few in a cylindrical geometry [7][8][9][10].…”

Abstract:In order to solve the aluminum surface ablation issue of Al-Steel bimetallic pipes manufactured by the explosive welding technique, a novel explosive welding system has been designed to weld Al-Steel coaxial pipes. The stand-off distance was chosen according to an empirical formula. A special Explosive Cord with an aluminum coating was used as the explosive. Four experiments were performed using Explosive Cords 1, 2, 3 and 4, respectively. In each experiment, three reliable PVDF (Polyvinylidene Fluoride) piezoelectric film sensors were used to sample the impact pressure between the parent pipe and the flyer pipe along the detonation direction. p-t Curves were obtained at different points on the bimetallic pipe manufactured by Explosive Cord 1. In order to observe the inner surface and to judge the bonding interface, specimens were cut along the axial direction. BSE (Backscattering Electron) images of the interfaces were obtained. According to these pictures from all of the specimens cut along the axial direction, the surface ablation phenomenon has disappeared. The bimetallic pipe manufactured by the new welding system using Explosive Cord 3 has an irregular wavy interface, between micro and small wavy interface, which is one of the best bonding forms.

“…As such, multilayer metal composite sheets, which are bonded by two or more metals, have been developed to replace monolithic metal sheets in many instances [20]. This type of materials is proven to have superior comprehensive properties compared with monolithic metal sheets, such as strength-to-weight efficiency, high electrical and thermal conductivity, wear, and corrosion resistance [21]. Besides, multilayer metal composite sheets are necessary when the two sides of the components are in different physical and chemical environments [22].…”

Abstract:Multilayer metal composite sheets possess superior properties to monolithic metal sheets, and formability is different from monolithic metal sheets. In this research, the feature size effect on formability of multilayer metal composite sheets under microscale laser flexible forming was studied by experiment. Two-layer copper/nickel composite sheets were selected as experimental materials. Five types of micro molds with different diameters were utilized. The formability of materials was evaluated by forming depth, thickness thinning, surface quality, and micro-hardness distribution. The research results showed that the formability of two-layer copper/nickel composite sheets was strongly influenced by feature size. With feature size increasing, the effect of layer stacking sequence on forming depth, thickness thinning ratio, and surface roughness became increasingly larger. However, the normalized forming depth, thickness thinning ratio, surface roughness, and micro-hardness of the formed components under the same layer stacking sequence first increased and then decreased with increasing feature size. The deformation behavior of copper/nickel composite sheets was determined by the external layer. The deformation extent was larger when the copper layer was set as the external layer.

“…Current research in the field are oriented towards welding dissimilar materials (welded plates have different materials) used especially in the construction of parts specific to the aerospace industry, transport, automotive industry, electric power industry [4][5]. Aluminum and copper are two common metals in the electric power industry, but the dissimilar combination of aluminum and copper is generally difficult for fusion welding because of the wide difference in their physical, chemical and mechanical properties [6][7][8].…”

Abstract. Aluminum and copper are two common metals and Al-Cu joints are commonly used in the power industry. Overlay joints of 3105 aluminum alloy and commercially pure copper were produced by FSW, microstructure and mechanical properties was investigated. A combination of optical and scanning electron microscopy is used to characterize the microstructures in the copper and heat affected zone in the aluminum near the fusion line. The hardness distribution was analyzed and residual stresses were measured at the stir zone, copper side and aluminum alloy side.
