Reasons for failure of the laser nozzle during laser cutting

Today, the leapion laser gives you a better understanding of the causes for failure of the laser nozzle during laser cutting. In the previous article, we discussed the effect of the nozzle on the efficiency of laser cutting and some considerations during the use of the nozzle.

If you have a problem with the malfunction of the nozzle during the cutting process, how to deal with it in time.

With the rapid growth of the social economy, fiber laser cutting machines focus on the advantages of "low energy consumption, no pollution, simple operation" that are fast becoming common.

However, due to certain inappropriate operating factors, people can obstruct or harm the laser nozzle.

This results in the precise cutting of the laser cutting head which affects the operating life of the cutting unit.

This essay reflects on the key causes of failure of the laser nozzle.

Please, join me.

First of all, we know that the laser cutting nozzles have both single and double layers.

The diameter of the nozzles varies from 1.0 mm to 3.0 mm and has 5 taper holes.

Ses features do not guarantee that the nozzle dissipates heat and that it is not easy to get slag.

However, due to the characteristics of the nozzle itself and the efficiency of the cutting system, it is easy for the nozzle to wear out.

1. The "chip" nozzle, the opening becomes wider than the fiber laser cutting unit.

The single-layer laser nozzles are quickly deformed by soft material defects.

In the course of mechanical action, the nozzle would be in close contact with the slag.

2. The nozzle is deformed and the slag particles affect the interior of the lens.

There are two situations in the laser cutting process:

When the laser cutting head is in the vertical direction, the mechanical sensing safety system slows the machine.

And, inevitably, people can see the collision from the horizontal direction as a collision with the laser cutting head due to the raising of the cutting material.

The sensor safety system will interrupt mechanical activity in time when the laser cutting head is stressed.

And the nozzle comes in close contact with the material, allowing the nozzle to bend.

Continue cutting; when the laser head is lightly stressed, the sensing safety system would not be able to shut down the unit in time, allowing the nozzle to penetrate the slag.

And the high-pressure airflow can blast the slag onto the laser head to cause loss.
