How does the pulse waveform of Manhart (Guangdong) CNC Machine Tool Co., Ltd.’s laser welding machine affect the welding effect?

The impact of pulse waveform of laser welding machine on welding effect is mainly reflected in multiple aspects such as welding quality, welding speed, and welding stability. The following is a specific analysis:
Firstly, the shape and parameters of the pulse waveform directly affect the energy distribution and transfer during the welding process. The height and width of the waveform determine the output and duration of laser energy during the welding process, which directly affects the depth and width of the welding. The higher the height of the waveform, the greater the welding depth; The wider the waveform width, the larger the welding width. Therefore, selecting appropriate waveform parameters based on specific welding requirements is crucial for achieving ideal welding results.
Secondly, the frequency of the pulse waveform also affects the welding speed and the smoothness of the weld surface. The higher the frequency, the more laser pulses per unit time, and the corresponding increase in welding speed. Meanwhile, an appropriate frequency also helps to form a smoother and more uniform weld surface, improving welding quality.
In addition, the pulse waveform can also affect the stability of the welding process. A stable pulse waveform can ensure the continuous and uniform transmission of laser energy, reduce fluctuations and unstable factors during the welding process, and thus improve the stability and reliability of welding.
Especially for welding high reflectivity materials such as copper, aluminum, gold, silver, etc., the selection of pulse waveform is particularly important. By using a laser waveform with front spikes, the metal surface condition can be quickly changed at the beginning of welding, reducing the material’s reflectivity to the laser, thereby improving the utilization of laser energy and welding quality.
Therefore, when choosing a laser welding machine, it is necessary to choose the appropriate pulse waveform based on the specific welding material and thickness, as well as the required welding effect. At the same time, in the actual welding process, it is necessary to continuously adjust and optimize the pulse waveform parameters based on the welding effect feedback, in order to achieve the best welding effect.
In summary, the pulse waveform of laser welding machines is one of the key factors affecting the welding effect. Reasonable selection and optimization of waveform parameters are of great significance for improving welding quality and efficiency.
