In order to solve the existing problems in the explosive welding technology of clad metal plate, such as low utilization rate of explosive energy, environment harm and potential safety hazard, a simple closed explosive charging process, namely a production method of energy-saving explosive welding of clad metal plate, was designed. More precisely, an isolation plate with a thickness about 2 mm was placed on the surface of ordinary explosive, and a 10~12 mm height emery sands layer was laid on the isolation plate. Then, experimental research was conducted to verify the difference of the mechanical properties between the energy-saving explosive welding and the ordinary explosive welding. Non-destructive testing and mechanical properties tests showed that the interface binding strength, binding rate and mechanical properties of clad metal plates produced by the energy-saving explosive welding technology could meet or exceed the technical requirements of the national standard GB/T 8165 and industry standard NB/T 47002. The new method of covering something on the explosive surface can achieve the purpose of saving 1/3 energy compared with the ordinary explosive welding process. And even under the condition of reducing the explosive consumption by 30%, the mechanical performance index of the clad metal is still higher than the national and industrial standards. The experimental results show that the mechanical properties of the clad metal produced by the energy-saving explosive welding process and ordinary explosive welding process are almost the same, which can meet the needs of large-scale chemical equipment manufacturing field. Therefore, the production process of clad metal plate by the method of energy-saving explosive welding is simple, efficient, safe and reliable, and the purpose of saving energy as well as reducing consumption is realized.
