“…Explosive welding is a face-to-face welding technology that can effectively control the thickness of IMC layer [5][6][7] . However, in the welding of high-hardness aluminum alloy and stainless steel a thick IMC layer appears at the interface, often leading to welding failure 8 .…”

In this work, interlayers with different thickness were used to weld A6061 aluminum alloy and SUS 821L1 duplex stainless steel. The results indicated that the interlayer thickness had a significant effect on the welding. The influence of the air shock wave between the plates on the welding results was examined. The fluid-Solid coupling finite element method was used to simulate the movement of the interlayer under the action of the air shock wave. The smoothed particle hydrodynamics method was used to simulate the oblique impact process of the plates, and the unwelded samples were analyzed using the simulation results. In the analysis of weldability window, the influence of the interlayer on the upper and lower limits was examined.

“…These findings are in agreement with previous research which has also suggested that the bond interface possesses a higher strength compared to the weaker matrix metal in the joint. [53][54][55] Moreover, the bonding interface at the macroscale exhibited an absence of cracks, thus providing further evidence of an ideal bonding strength. Furthermore, the occurrence of anchor formations at the weld interface played a significant role in enhancing bonding strength through the establishment of an interlocking mechanism.…”

This study explores the feasibility of explosive welding to join dissimilar materials: aluminum (JIS A1050‐H24) and two cast iron types (JIS G 5501 and JIS G 5502), which are challenging to weld due to the presence of graphite in the cast iron. Further, the impact of explosive thickness (28, 38, and 47 mm) on weld quality is investigated, considering microstructure and mechanical behavior. Increasing explosive thickness correlates with a thicker local melted zone. Remarkably, in investigations, a novel morphology that diverges from conventional patterns is observed. The weld interface of explosively bonded materials exhibits anchor formation, a unique interlocking structure. These anchors play a significant role in establishing a robust mechanism between bonded surfaces. JIS A1050‐H24 shows minimal hardness variation, while cast iron exhibits significant variations with increased explosive thickness. Tensile shear tests showcase robust clad plate strength, with fractures primarily in JIS A1050‐H24 regions instead of at the interface. The highest tensile shear strength is achieved with an explosive thickness of 38 mm. Overall, explosive welding of aluminum with cast iron creates a strong, durable, and lightweight material with enhanced performance characteristics, making it promising for diverse industrial applications due to its outstanding properties.

“…The planar region consisting of any two of the three welding parameters (collision velocity V p , collision angle β, collision point velocity V c ), which is called an explosive welding window, is usually established to predict the bonding quality of explosive welding. One of the most commonly used explosive welding windows is the one based on the theory of Deribas et al [13]. The explosive welding window typically described by collision point velocity V c and collision angle β as horizontal and vertical coordinates.…”

In order to improve the energy utilization rate and the bond quality of explosive welding, the local water environment method is used in present study.In this paper, several groups of high-quality Cu/Steel explosive composite pipes are prepared under local water environment. Optical microscope and mechanical property tests are conducted to analyze samples microstructure and mechanical properties. The results show that the waveform dimension of Cu/Steel bonding interface has a positive correlation with explosive layer thickness, and the miniature wavy bonding interface with the highest bonding quality is obtained by using the local water environment method. Compared with the traditional charge method, the consumption of explosives for the local water environment charge method is decreased about 60 % in the same case of experimental conditions. The local water enviroment method solves the problem of ablation damage at the contact surface between metal and explosives, and effectively reduces the diameter expansion phenomenon and end damage caused by boundary effect in the welding process. Through mechanical property tests, it was found that the yield strengths and compressive strengths of Cu/Steel specimens which created by the local water environment method are positively correlated with the explosive thickness.
