How does Manhart (Guangdong) CNC Machine Tool Co., Ltd. choose the appropriate pulse waveform based on different materials and thicknesses?

Choosing the appropriate pulse waveform is crucial for the welding effect of laser welding machines, especially for welding objects with different materials and thicknesses. Here are some suggestions to help you choose the appropriate pulse waveform based on different materials and thicknesses:
Firstly, consider the type and characteristics of the material. For high reflectivity materials such as copper and aluminum, it is necessary to choose waveforms that can quickly change the surface state of the metal and reduce reflectivity, such as laser waveforms with front spikes. This waveform can instantly improve energy utilization at the beginning of welding, thereby improving welding quality. For low melting point metals, oblique waves may be a good choice because they have a larger heat input and can avoid excessive diffusion of the molten pool.
Secondly, the thickness of the material is also an important factor in determining the pulse waveform. For thicker materials, it may be necessary to choose waveforms with longer pulse widths and higher energy to ensure that sufficient heat can be transferred to the depths of the material, achieving complete penetration. For thinner materials, shorter pulse widths and lower energy may be more appropriate to avoid excessive melting and burning through.
In addition, welding requirements are also factors to consider when selecting pulse waveforms. If high-precision welding is required, pulse wave may be a good choice as it can provide highly controlled heat input and accurate positional loading. For situations that require rapid welding, it may be necessary to choose waveforms with higher repetition rates.
Finally, experience accumulation in practical operation is also very important. In the actual welding process, based on the feedback of the welding effect, continuously adjust and optimize the pulse waveform parameters to find the waveform that is most suitable for specific materials and thicknesses.
In summary, selecting the appropriate pulse waveform requires comprehensive consideration of multiple factors such as material type, thickness, and welding requirements. By constantly trying and optimizing, you can find the pulse waveform that is most suitable for your specific application, thereby improving welding quality and efficiency.
