Laser welding machine is a machine used in the field of welding, is one of the important aspects of laser material processing technology application. According to its working mode, it can be divided into laser mold and welding machine, automatic laser welding machine, laser spot welding machine, fiber laser welding machine, etc.,
Laser welding uses high energy pulsed laser welding parts. It uses pulsed xenon lamps as a pump source and as a laser working material. The laser power source pre-ignites the pulsed xenon lamp, and the pulsed xenon lamp is discharged through the laser power source, so that the xenon lamp can generate light waves of a certain frequency and pulse width. The light wave shines on the laser crystal through the focusing cavity, which stimulates the laser crystal to produce laser light, and then produces a pulsed laser with a wavelength of 1064nm after passing through the resonant cavity.
The laser is radiated to the surface of the workpiece after the beam is extended, reflected (or fiber transmitted) and focused, and the workpiece is partially melted to achieve welding. The frequency, pulse width, moving speed and moving direction of the pulsed laser required for welding can be controlled by PLC or industrial PC, and the laser energy can be controlled by adjusting the current, laser frequency and pulse width.
Regularly check the conductivity of the inner circulating water, insist on replacing the inner circulating deionized water once a month, pay close attention to the color change of the ion exchange column in the cooling system, and deal with the abnormal color in time.
In high temperature or humid environment, pay attention to avoid "condensation" phenomenon. After a long period of continuous work, the laser welding machine should be stopped for a period of time to allow the equipment to rest. Before the next startup, check the components in the optical path, such as the dielectric diaphragm and the protective lens, to ensure that everything is normal before continuing to use.
