The pulse power heating method is a method of heating the welding by using Joule heat generated when a pulse current flows through high resistance materials such as molybdenum and titanium.Generally, a hot spot is connected to the front of the thermal head. The thermocouple converts the temperature on the thermal head into a signal and feeds it back to the power control center in real time. The power control center controls the temperature and temperature of pulse heating according to the set temperature and time in the system. Time to ensure temperature accuracy. Advantages of pulse hot press heating: 1. Pressurized colleagues apply heating and power-off cooling at the same time to prevent the welding parts from floating and welding. 2. Excellent reproducibility of parameters such as temperature and time can realize high quality production. 3. The local instantaneous heating method can well control the thermal influence on surrounding components. 4. Fast heating and high welding efficiency.
