Laser welding equipment uses the pulse laser with the wavelength of 1080nm generated by the laser to radiate the surface of the workpiece after beam expansion, reflection and focusing.

The surface heat is guided by heat transfer and diffused internally. Through digitization, the width, energy, peak power, repetition frequency and other parameters of the laser pulse are accurately controlled to melt the workpiece and form a specific molten pool, so as to realize laser welding of the workpiece, Complete precision welding that cannot be achieved by traditional process.

Laser welding is mainly aimed at the welding of thin-walled materials and precision parts, which can realize spot welding, butt welding, lap welding, seal welding, etc. with high depth width ratio, small weld width, small heat affected zone, small deformation, fast welding speed, flat and beautiful weld, and no treatment is required after welding. It can be accurately controlled, with small focusing light points, high positioning accuracy, and easy to realize automation.

Then, what problems should be paid attention to in the use of laser welding machine?

Today, HGTECH editor in chief is here to talk about the matters needing attention in the operation of laser welding machine. I sincerely hope it can help you.

1. Pay attention to dust prevention in the appearance of equipment host and welding joint.

2. Do not stack sundries on both sides of the water machine and keep a space of 1 meter to ensure ventilation and refrigeration.

3. Check the protective lens of the welding joint at the morning shift every day, and then turn on the machine for air supply.

(when checking, pull out half of the protective mirror drawer to see the middle position of the lens.)

4. In case of energy weakening during welding, stop the machine immediately and check the protective lens. The inspection method is the same as above. If there is black burning point, replace it in time.

5. Precautions when replacing protective lenses.

1) First turn off all air blowing and blowing equipment near the welding joint. Reduce air flow.

2) Wipe the periphery of the protective mirror drawer with a dust-free cloth dipped in alcohol or acetone.

3）After removing the protective mirror drawer, immediately seal the window of the protective mirror drawer with masking paper to prevent dust from entering the welding joint.

4）When replacing the protective lens, do not touch the surface of the lens, and hold the side of the lens.

5）After changing the lens, use a blowing balloon to blow away the floating dust on the surface.

6）Remove the masking paper and replace the protective mirror drawer in the correct direction.

7） Welding smoke should be reduced as much as possible. If there is too much smoke, dust extraction equipment should be equipped to remove the smoke.
