Common problems and their solutions during the use of handheld laser welding machines.

In the current welding field, the use of handheld laser welding machines has become very common. It is very popular among users due to its advantages such as convenient operation, portability, fast welding speed, and high product yield. However, when using a handheld laser welding machine, there may be some problems. The following is a list of common faults of the laser welding machine and how to deal with them.

The solubility of laser welding machine welding is not enough

1.It can be solved by increasing the pulse width and increasing the current, or adjusting the defocus amount close to the point position.

2.Cracks appear when laser welding machine welding

It can be solved by reducing the air flow of the protector, or reducing the temperature of the cooling water and increasing the water temperature. If the workbench is not cleaned, you can clean the workbench again.

3.If the weld seam is very deep when the laser welding machine is welding

It is necessary to use nitrogen or other inert gases in time, or adjust the airflow direction of the protector to be opposite to the movement direction of the workpiece.

4.If the laser beam weakens when the laser welding machine is welding

It can be solved by changing the cooling water. If the laser in the main optical path deviates, you need to adjust the full-reflective or semi-reflective diaphragm of the main optical path.

5.If an open flame does not fully pop

You need to check whether there is any remaining lubricating oil on the shutter connection.
