THEORETIC ANALYSIS ON TEMPERATURE ASCENDING OF EXPLOSIVE WELDING INTERFACE |
| |
| Abstract: | The temperature of the explosive welding interface affects welding quality directly in the process of explosive welding,so it is an important aspect of theoretic study on the explosive welding.Based on factors that cause the temperature ascending of the explosive welding interface were analyzed theoretically,the conclusion was drew that the temperature rising of the explosive welding interface also included adiabatic compression of gas besides shock temperature and abnormality deforming energy between the basic plate and fly plate.The shock temperature between the basic plate and fly plate could be calculated by Hugoniot equation and free-electron gas model,Johnson-Cook's thermal visco-plasticity constitutive equation was used to calculate the temperature rising caused by the abnormality deforming energy,and the temperature rising caused by adiabatic compression of gas could be deduced by gas equation of state. |
