Principle of nanoscale Laser welding machine
The work of laser welding is to apply high energy pulse laser to realize welding. The laser power supply first points the pulsed xenon lamp through the excitation.
The light power supply to the xenon lamp pulse discharge, forming a certain frequency, a certain pulse width of the light wave, the light wave through the spotlight cavity radiation to Nd3+:
On the YAG laser crystal, the Nd3+:YAG laser crystal luminescence is excited. After the resonance of the laser resonator, the wavelength is emitted.
A 1064nm pulse laser, which is hit after the beam is expanded, reflected, (or transmitted through fiber) and is focused on the object to be welded.
On the body, the welding is completed under the control of PLC or industrial PC machine.
1. mainly for thin-walled materials, heterosexual metal material precision parts welding, can realize spot welding, superposition welding;
2. high stability laser output
3. high monopulse energy
4. high marking efficiency
5. short pulse setting time
6. high reliability and maintenance free operation
7. can be accurately controlled, small focus light point, high precision positioning, easy to realize automation.
