Laser nozzles have a wide range of applications in multiple laser processing fields. The following is a detailed summary of their applications:

Laser cutting industry: Laser nozzle is a key component in laser cutting equipment, mainly used for fine cutting of metal and non-metal materials, such as steel plates, copper, aluminum and other materials.

During the cutting process, the laser nozzle guides the gas to form high pressure, helping the laser to perform cutting. The smaller the nozzle outlet aperture, the higher the air pressure formed, which helps to improve cutting efficiency and accuracy.

Laser marking industry: Laser nozzles are also commonly used for marking, engraving, and marking materials such as plastics, metals, and rubber.

The design of the nozzle and airflow control have a significant impact on the marking effect, such as the size of the nozzle mouth directly affecting the pressure distribution at the nozzle outlet, which in turn affects the marking quality.

Laser welding industry: In the laser welding process, laser nozzles are mainly used for welding materials such as metals and plastics.

By guiding the gas, the laser nozzle forms a protective layer in the welding area, preventing oxygen from oxidizing the welding surface and helping to remove impurities in the welding area, thus improving the welding quality.

Electrical signal collection and location tracking: Laser nozzles also have the function of collecting electrical signals. The collected electrical signals are transmitted through a ceramic ring to a signal processor, which sends signals to the control center of the machine tool. The control center determines the position of the laser head based on the electrical signals and provides feedback to adjust the vertical position of the laser head.

This function enables the laser nozzle to track the distance between the laser head and the workpiece during laser processing, ensuring processing accuracy and stability.

Protecting the internal lenses of the laser head: During laser cutting, especially during drilling, there is often slag splashing. The high-pressure gas blown out by the laser nozzle can block most of the sputtering material outside, protecting the lens from damage.

Improve production efficiency: The use of laser nozzles can shorten processing time and improve production efficiency. For example, nozzle laser drilling machines have been widely used in the processing of complex shaped parts due to their advantages of saving processing time, fast processing speed, and high accuracy.

In summary, laser nozzles play an important role in fields such as laser cutting, marking, and welding. It helps achieve high efficiency, precision, and stability in laser processing by guiding gas, collecting electrical signals, and other functions. Meanwhile, the design and manufacturing of laser nozzles are also of great significance for improving the quality and efficiency of laser processing.
