Practical aspects of using a laser welding machine

In this section, we will discuss the practical aspects of using a laser welding machine, including technical settings, maintenance, and the cooling system and shielding gases.

Technical parameters and settings: laser source power, wavelength and penetration depth

The technical parameters of a laser welding machine are crucial to the quality and efficiency of the welding process. The three main parameters to pay attention to are the power of the laser source, the laser wavelength and the depth of penetration.

The power of the laser source affects the speed and quality of welding. Higher power allows for faster welding and a better combination of materials, but it can also cause a higher risk of deformation. Therefore, it is important to choose the right laser power for the type of material and thickness of the parts to be welded.

The wavelength of the laser determines the laser’s ability to penetrate the material. The wavelength affects the absorption of energy by the material, which directly affects the quality of the weld. The wavelength of the laser should be selected according to the type of material to be welded.

Penetration depth is the distance the laser energy penetrates the material. The depth of penetration depends on the laser power, wavelength and material properties. For optimal results, the penetration depth should be adjusted according to the thickness of the material and the type of joint.

Cooling system and shielding gases: how to take care of a laser welder

The cooling system is an indispensable component of a laser welder, which ensures the proper operating temperature of the device. The cooling system can be water-based or air-based, depending on the model of the welder. It is important to regularly check the condition of the cooling system, clean the filters and refill the coolant to ensure the long life of the laser welder.

Shielding gases are used in laser welding to protect the weld surface from chemical reactions with the environment. Shielding gases, such as argon or helium, form a protective layer around the weld, preventing oxidation and other adverse reactions. Regular checking and refilling of shielding gas is key to maintaining high weld quality and long-term use of the laser welder.

In summary, the practical aspects of using a laser welder include both proper settings of technical parameters such as laser source power, laser wavelength and penetration depth, as well as taking care of the cooling system and the use of shielding gases. Regular maintenance and inspection of these components will ensure the long life of the laser welder and high quality welds.
