Laser welding machine

Equipment technology information

Equipment mainly technical parameters

1. Laser

The laser spotlighting cavity use the newest combination cavity structure, and make the laser have high photoelectric conversion efficiency, good quality of light beam, and work stably and reliably. Which make up of optical bench, spotlighting cavity, YAG crystalloid, pump xenon lamp, diaphragm frame and engine cover etc.

Laser work substance:   Nd: YAG crystalloid

 Laser wavelength: 1.06um
 Number of Xenon lamp: single lamp pump

 Laser energy of single pulse: ≥50J

 Energy unstability: ≤±2％ 

 Laser pulse Width: 0.1-20ms Grading adjustable

 Pulse frequency: 1-100HZ  Grading adjustable

Continuous operating time: ≥ 24h

2.  Cavity

Laser cavity uses combination cavity with gold-plated copper, and tube posture structure, segregate cooling water and metal gold-plated surface completely, stop corrosion of cooling water to cavity. And uses the device of beach reflection, eliminate the impact of cooling water to crystalloid.

Meanwhile, the cavity has the feature, don’t need dimming after replace xenon lamp.

3.  Laser power

Laser power uses the newest switch power designed by our company. The power work stably, and the influence of the external power grid is low.

Power can realize modulation waveform of pulse. Operating current, pulse width and frequency adjustable.

Setting waveform can be showed directly in the power panel. The mainly technical parameters of the power are:

Input power: 380v±5％

Power rating: 6Kw

Pulse operating current: 100-300A

Power unstability: ≤±2.5％

Continuous operating time of power: ≥20h

Laser power controls laser output by using internally piloting button, and have the over electric flow over voltage protection function and multiple real-time detection point.

Detect the false signal in the procedure of laser, indicate the position of the false in the computer panel, and good for checking and maintenance.

4. Beam splitting system

Beam splitting system uses the way of diaphragm beam splitting, make the main light path laser into 3 or 4 by this way(it depends on the demand of customer) 

The energy deviation among light beams: ≤2%  

The fiber uses Fibertech fiber imported from Germany

The core diameter of fiber: 0.4mm

Fiber length: 5m

Fiber form: SI or GI

Fiber equipped with artificial gems which prevent laser of its bottom and guarantee the service life and non-damage of fiber.

5.Focusing system

Uses multiple compound focus drum to focus laser

Focusing focal length: f=120mm

Focusing girdling length: ≥3.0mm

Output energy of single light path: ≥8J

6. Pulse waveform modulation    

Can set laser output waveform depending on technics requirement of laser processing. It guarantees energy error not more than 1% every time since uses energy feedback system.

Pulse waveform can be compiled and adjust in sections, based on the material, diameter etc. of the welding workpieces.

7. Energy real-time control feedback system

Laser power installed energy real-time control feedback system, which can monitor and show to the main light path energy in the process of operating, feedback and adjust based on the setting energy, then guarantee the stability of laser energy output.

Cooling system

The cooling system of the machine uses air-cooled way, and doesn’t need to add a external cycle cooling system outside.  

The cooling efficiency of the machine can work regularly more than 20 hours.

Cooling system uses purryag water box, avoid the pollution from the water produced by metal water box.

The cooling system includes: water pump, temperature controller, target flow and so on.

9. Operating platform

The machine uses operating platform separating from laser(includes laser power).

The platform uses humanity design and is convenient to long time usage for handlers, which will not feel tired.

The platform uses upper shield, with built-in LED glaring panoramic lighting, which make the work images by magnifying without the dark spots (shadow)

10. Mechanical drive part

Manual lifting work table adopts transmission mode of worm turbine, which is stable, no clearance, no jitter phenomenon in the transmission process.

Lifting work table’s distance: 100mm

Focusing tube stents adopted four D fine-tuning stents. The links between among the four D stent is stable and reliable. The straight line 3 D direction adjusted with micrometer.

11. Display system

Equipped with 17 "LCD (black and white) for operation to observe the display system.

12. CCD camera system

Equipped with 2 sets 20* magnification CCD camera system, CCD camera system uses three road coaxial monitoring way to implement.

13. Red light indicating system

Indicating system is formed by red laser and precision adjustment frame to be the adjustment base of light path.
