Detailed Working Process and Parameter Introduction of Laser Welding Machine
The laser welding machine is an advanced welding equipment, and its working process and parameters are crucial for achieving high-quality welding results.
Working process:
The operation of the laser welding machine starts from the laser generator, which generates a high-energy laser beam. This laser beam passes through a series of optical elements, such as mirrors and lenses, and is focused onto a very small point, forming an extremely high energy density.
When the workpiece to be welded is accurately placed at the focal point of the laser beam, the energy of the laser instantly melts or even vaporizes the material on the surface of the workpiece. In the molten state, the material flows rapidly and fuses together to form a strong weld seam.
During the welding process, protective gases, such as argon or nitrogen, are usually used to prevent the welding area from oxidation and improve the welding quality.
Main parameters:
Laser power: This is a key parameter that determines the welding depth and speed. The higher the power, the stronger the welding ability. However, a reasonable selection should be made based on the characteristics of the material and the welding requirements.
For example, for thicker metal plates, a high-power laser may be required to achieve effective welding.
Welding speed: It affects the width of the weld seam and the heat input. Too fast a speed may lead to an unstable weld, while too slow a speed may cause excessive heating and a large heat-affected zone.
For example, in fine welding, a slower speed is needed to ensure accuracy.
Focal point position: The accurate setting of the focal point is directly related to the welding quality. The position of the focal point above, on, or below the surface of the workpiece will produce different welding effects.
For materials of different thicknesses, the focal point position needs to be adjusted accordingly.
Pulse width and frequency: In pulsed laser welding, the pulse width determines the energy of each pulse, and the frequency affects the continuity of the welding.
Short pulses are suitable for thin plate welding, and long pulses are suitable for thick plates.
In conclusion, understanding and reasonably setting the working parameters of the laser welding machine are of great significance for fully exerting its performance and achieving the ideal welding effect.
