    • Abstract
  • A 5 kW light beam brazing equipment has been developed and tested.A sphere large-power short arc xenon lamp is used as the light source of this equipment.Deep ellipsoidal optical focusing system,cooling system and power source are designed reasonably.Major performance parameters of this equipment are tested and the brazing process is examined.The result shows that input power of this equipment can be regulated continuously from 600 to 5000 W.The minimum diameter of light beam spot is 15mm.The maximum heating temperature on blackbody can reach up to 1800℃.Brazing of ordinary materials with Sn-based and Ni-based filler metals are successfully performed.This equipment can be further developed into the surface modification processing of materials because of its high and concentrated energy.
