| 摘 要： | 0IntroductionResearch of temperature field near stagnation pointquantificationally is of great importance to control the qual-ity of explosive welding. If the temperature at the weldinginterface is too high the material will melt in excess andthe metal plates can not be welded well and if the tempera-ture is too lowthe plates can not be well-knit. At the sametime to calculate the heat behavior in the flow field of ex-plosive welding quantificationally is the basis to analyze themetallurgic eff…

| Abstract: | Energy deposition at the interface of explosive welding is analyzed by symmetrical impaction model of uneompressible liquid. Equation of energy in the flow field of explosive welding is deduced and the distribution of temperature in the flow field is solved by finite difference method on the basis that the adiabatic compression is considered. The results show that the temperature rise increases with the increasing of the velocity of approaching flow and impact angle, under appropriate velocity of approaching flow and impact angle the temperature rise near the welding interface will be higher than the melting point of the material and the thin melted layer is localized on the region near welding interface. |
