Handheld laser welding machines are very common at present, and are highly supported by manufacturers because of their convenient operation, easy portability, fast welding speed, and high product output. So when we use the handheld laser welding machine, we may have some problems. So, how to solve this problem? The following are common faults of laser welding machines and their solutions.
1. Laser welding machine welding solubility is not enough:
Increase the current by increasing the pulse width, or adjust the off-focus position.
2. Cracks appear during welding by laser welding machine:
It can be solved by reducing the flow rate of the protector, or reducing the temperature of the cooling water and increasing the water temperature. If the workbench is not cleaned, you can re-clean the workbench.
3. If the weld seam is deep when the laser welding machine welds:
It is necessary to use nitrogen or other inert gas in time, or adjust the airflow direction of the protector, which is opposite to the movement direction of the workpiece.
4. If the laser beam is weakened when the laser welding machine is welding:
It can be solved by changing the cooling water. If the main optical path laser is deviated, it is necessary to adjust the main optical path total return or semi-reflection film.
5. If the open flame does not fully bounce:
Check for grease residue on the shutter connections.
The above are the common faults and treatment methods of laser welding machines, I hope to help you.
