Problems solved by technology

[0002] The laser welding machine uses high-energy pulsed laser to focus and melt the target metal to weld between workpieces. It has the advantages of fast welding speed, large depth, small deformation, welding at room temperature, and simple welding equipment. The power control part is used as An important part of the laser welding machine, its working performance directly affects the quality of the welding result. The power control part mainly controls the pre-combustion circuit of the laser welding machine to emit high voltage to control the xenon lamp to emit pulsed light to ensure the operation of welding , and the pre-combustion control boards of most existing laser welding machines are too easy to be burned out, and it is not easy to maintain and repair after burning out. Generally, there is only one high-voltage transformer, which cannot reach the xenon lamp after receiving the pulse voltage after aging. pre-ignition high pressure
