Abstract :
A new type of testing device is designed for energy of laser pulse in this paper. By using it, pulse energy of KJG-1YAG-400A laser welder can be measured. The calorific models have been established for the device, and the analysis of thermal loss has been finished. Running curves have been obtained between time and resistance after the device absorbing laser energy. After test data is amended, the relationship among single pulse of laser energy, pulse width and current has been revealed, which provided theoretical foundation and practical experience for the laser brazing process.
