Definition of condensation: put the object in a certain temperature, humidity and pressure environment, and gradually reduce the temperature of the object. When the ambient temperature of the object drops below the "dew point temperature" of the environment, the moisture in the air gradually reaches a saturated state until dew is deposited on the surface of the object. This phenomenon is called dew condensation.

To put it simply: there is water vapor or water droplets on the surface or inner wall

How to Avoid Laser Condensation

1. Avoid condensation inside and outside the laser without air conditioning

When using a laser that does not have its own air conditioner and is exposed to the working environment, once the cooling temperature is lower than the dew point temperature of the laser environment, moisture will be precipitated on the electrical and optical modules. Condensation will start to form on the outer surface of the laser. Therefore, once you see condensation on the laser shell, it means that the internal environment has condensed. The work must be stopped immediately, and the working environment of the laser must be improved immediately.

2. Avoid dew condensation inside and outside the laser with its own air conditioner

The laser with its own air conditioner may still cause condensation in the internal environment. When using a laser with its own air conditioner and exposed to the working environment, the cooling and dehumidification of the air conditioner will greatly reduce the dew point temperature of the environment inside the laser. Generally, the cooling temperature of the industrial air conditioner is set to be the same as the cooling water temperature.

When the ambient temperature is lower than 38°C, the industrial air conditioner can maintain the safety of the environment inside the laser, but there may be condensation on the surface of the laser housing. If the condensation does not form flowing water droplets, it is safe. If there are a large number of flowing water droplets and there are obvious water spots around the laser, a safe and non-condensing working environment must be established for the laser with air conditioning.

When the ambient temperature is higher than 38°C, the cooling capacity of the industrial air conditioner is not enough to maintain the safety of the internal environment of the laser, and condensation will still occur in the internal environment. After a long time, the external environment will also follow the condensation. Therefore, there should be no obvious heat source around the laser, and the hot air outlet of the water cooler should not face the laser.

In order to eliminate the risk of condensation in the laser environment, it is recommended to configure an independent air-conditioning room for the laser.

3. Avoid dew condensation in the processing head

If the processing is abnormal when the season changes or the temperature changes greatly on the day, you can check whether there is condensation in the processing environment.
