Precautions for maintenance of laser welding machine

Laser welding machines are also often called laser welding machines, negative energy feedback laser welding machines, laser welding machines, laser welding machines, laser cold welding machines, laser argon welding machines, laser welding equipment, etc. Laser welding machine is to use high-energy laser pulse to locally heat the material in a small area. The energy radiated by the laser is directed to the internal diffusion of the material through heat transfer, and the material is melted to form a specific molten pool. So, what are the maintenance precautions of laser welding machine?

The laser welding machine needs maintenance, and the temperature of the water tank needs to be adjusted in winter and summer. Prevent too cold or too hot room temperature from affecting the laser output power. It is suggested that the temperature of the water tank can be adjusted to 3~5 degrees lower than the room temperature according to the room temperature, which can not only ensure the laser output power, but also ensure the stability of the laser output.

1. Water temperature setting

The temperature of cooling water has a direct impact on the electro-optic conversion efficiency, stability and condensation. Generally, the water temperature of cooling water is set as follows: the water temperature of purified water (also known as low temperature water, which is used to cool the laser welding machine module) should generally be set at about 21 ℃, which can be adjusted appropriately between 20 ℃ and 25 ℃ according to the situation. This adjustment needs to be made by professionals.

The water temperature of DI deionized water (also called high temperature water, used to cool optical components) should be set between 27 ℃ and 33 ℃. This temperature should be adjusted according to the ambient temperature and humidity. Generally speaking, the higher the ambient temperature, the higher the humidity, and the higher the DI water temperature should be. The basic principle is that the DI water temperature should be above the dew point.

2. Precautions such as internal electronic or optical elements

It is mainly to prevent the electronic or optical components inside the laser welding machine from condensation. Ensure that the chassis is airtight: whether the doors of each cabinet exist and are closed tightly; Whether the lifting bolts on the top are tightened; Whether the protective cover of the unused communication control interface at the rear of the chassis is properly covered and whether the used one is fixed. Keep the laser welding machine on and off and pay attention to the order. Install an air conditioning room for the laser welding machine, start the dehumidification function of the air conditioner and keep the air conditioner running continuously and stably (including at night), so that the temperature and humidity in the air conditioning room are maintained at 27 ℃ and 50% respectively.

3. Preventable failure

Laser welding machine is a high-tech equipment that converts electric energy into laser energy. Its internal structure is relatively complex, involving many disciplines and fields such as light, machinery, electricity, and computing. Ensure that the service environment meets the requirements and extend the service life of the equipment. For example, if the machine is switched on and off in the wrong order, it will lead to the case sealing and the water temperature setting, which may cause the electronic and optical components inside the laser welding machine that need to be cooled by water to condense on the surface due to the internal and external temperature differences, thus reducing the performance of the laser welding machine, and even damaging the laser welding machine.

The above is the analysis of the maintenance precautions of the laser welding machine, which is widely used in ma
