How does Manhart (Guangdong) CNC Machine Tool Co., Ltd. choose appropriate laser and welding parameters based on the material and thickness of the workpiece?

Choosing the appropriate laser and welding parameters based on the material and thickness of the workpiece is the key to achieving high-quality laser welding. Here are some basic selection principles:
1. Material type: Different materials have different absorption and reflection rates for lasers, so it is necessary to choose the appropriate laser and wavelength. For example, for materials with high reflectivity, pulse lasers or medium wavelength lasers can be chosen, while for materials with low reflectivity, continuous lasers or long wavelength lasers can be chosen.
2. Thickness: For thinner workpieces, lower laser power and faster welding speed can be selected to avoid overheating or excessive melting of the workpiece. For thicker workpieces, it is necessary to choose higher laser power and slower welding speed to ensure appropriate control of fusion depth and fusion width.
3. Laser pulse width: Pulse width is one of the important parameters of pulse laser welding machines. It is not only an important parameter that distinguishes from material removal and melting, but also a key parameter that determines the cost and volume of processing equipment. It is necessary to choose the appropriate pulse width based on the material and thickness of the workpiece.

4. Laser pulse frequency: Frequency is one of the important parameters of a pulse laser welding machine, which determines the ability of the laser to produce several pulses in one second. The higher the frequency, the smaller the energy output of each laser. It is necessary to select the appropriate pulse frequency based on the requirements of welding speed and weld quality.
5. Power density: Power density is one of the most critical parameters in laser processing of laser welding machines. The higher the power density, the faster the processing speed, but at the same time, the higher the material requirements. It is necessary to choose the appropriate power density based on the material and thickness of the workpiece, as well as the processing requirements.
In summary, selecting the appropriate laser and welding parameters requires considering multiple factors, including material type, thickness, processing requirements, etc. It is recommended to make choices under the guidance of professionals and adjust and optimize them according to actual situations to ensure high-quality laser welding.
