“…Thus, explosive welding is widely used in the preparation of laminated structures, such as Ti/Fe, Mg/Al, Cu/Al, Ti/Al, Ti/Cu, and Cu/Fe. [1][2][3][4][5][6][7][8][9][10][11][12] As titanium-steel composite plate has the corrosion resistance of titanium, the high strength of alloy steel, and a good comprehensive performance that can be directly welded with other offshore steel structures. It has become an indispensable structural material for the modern chemical industry, bridges, and ships.…”

Herein, the interface characterization and tensile properties of TA1/Q235 composite fabricated by explosive welding are investigated in the temperature range 650-950 °C. The explosive-welded TA1/Q235 composite presents the periodic wavy bonding interface with both the vortex and solid-solid bonding regions. Some defects, including cavities, cracks, and brittle intermetallic compounds, are located in the melted zone of the interface wave. The compound layer comprises FeTi and Fe 2 Ti, with a thickness of 25 μm. In terms of high-temperature tensile tests, the elongation of the TA1/Q235 composite exhibits a tendency of first increasing and then decreasing with increasing tensile temperature. And the elongation reaches the peak value of 95% at 800 °C. The tensile strength basically decreases with increasing temperature, except for a slight increase at 900 °C. The failure of the TA1/Q235 composite is affected by both the discontinuous compound and the continuous compound layers. With the increase in tensile temperature, a continuous compound layer with a certain thickness dominates the failure of the TA1/Q235 composite.

“…It is necessary to study the mechanism and improvement of explosive welding of pipes. Sui et al [6] proposed three kinds of explosive welding processes to solve the problem that aluminum pipe and stainless steel pipe are difficult to weld, and the explosive welding of LF6 aluminum alloy pipe and 1Cr18Ni9Ti stainless steel pipe was successfully realized; Mendes et al [7] studied the effect of explosion characteristics of explosives on the welding interface between 304 L stainless steel and 51CrV4 alloy steel; Zhou et al [8] introduced a unique explosive welding process that two groups of explosive welding pipes / rods were prepared at the same time in one experiment. The utilization rate of explosives was improved.…”

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.

The aim of this work is to study the use of explosive welding to produce Niobium-Steel composite plate, which is used in nuclear industry equipment material manufacturing. The welding parameters was determined by weldability window and numerical simulation was used to predict the wave shape of the welding interface. The morphology of the interface wave was observed by scanning electron microscope. Component measurement around interface waves. The experimental samples were investigeted using mechanical tests. The results show that the explosion parameters optimized by theory and numerical simulation can be used to obtain a niobium-steel composite plate with better welding quality. It can be proved that the welding quality is better by observing the interface wave and testing the mechanical properties, it can be seen that the melting zone of the welding interface is composed of niobium and steel by the composition analysis instrument. The morphology of the welding interface wave is consistent with the numerical simulation results, and the numerical simulation shows the changes of temperature, strain, and stress during the welding process.
