With its characteristics of precision, efficiency and low deformation, laser welding machine is widely used in the field of joining metal materials. Whether it is thin plate or thick plate material, it can show its unique welding advantages. Next, PES Laser will introduce to you the welding capabilities of the laser welding machine under different types of material thicknesses, as well as the welding depth it can achieve in the welding of thin plates and thick plates.

First of all, laser welding machines are particularly suitable for welding thin plate materials.

This technology uses a high-energy-density laser beam as the heat source, which can achieve micron-level precise focusing, thereby producing a very small heat-affected zone. For thin metal plates with thicknesses ranging from a few microns to a few millimeters, laser welding can achieve good penetration while keeping the weld seam narrow and smooth without the need for excessive post-processing.

For example, handheld laser welding machines are often used for welding ultra-thin stainless steel materials. Even 0.5mm stainless steel sheets can be effectively welded. Moreover, through positive defocusing technology, the weld surface can be ensured to be smooth and the heat-affected zone can be reduced to the maximum Retain the original properties of the material to the maximum extent possible.

For thick plate materials, laser welding machines also show strong welding capabilities.

As laser power increases, the thickness of materials that laser welding machines can process also increases. For example, for the common laser welding machines on the market ranging from 1000 watts to 6000 watts, the corresponding different welding depths are roughly as follows: 1000 watts to 3000 watts can process within 5 mm, and a 6000 watt laser welding machine can even complete 8 mm stainless steel plates. Welding tasks, the specific welding depth depends on the actual equipment.

Of course, the welding depth does not only depend on power, but also factors such as welding speed, defocus, and laser waveform. The appropriate combination of process parameters can enable laser welding to achieve stable deep penetration welding on thick plate materials and ensure the strength of the weld. and compactness.

It is worth noting that whether it is a thin plate or a thick plate, the laser welding machine can control the heat input and welding speed by adjusting the welding process parameters, thereby effectively suppressing welding deformation and improving welding quality and production efficiency. In thick plate welding, in order to obtain sufficient welding depth, in addition to increasing the laser power, multi-pass continuous welding may also be used to ensure sufficient fusion and penetration of the weld.

In addition, the laser welding machine can also cooperate with the automated control system to achieve real-time monitoring and precise control, which is particularly important for continuous large-volume welding of thick plate materials, and can effectively avoid cracks or other welding defects caused by local overheating.

Through the above content, we have made a detailed and professional introduction to the laser welding machine's ability to weld thin plates and thick plates, as well as the welding depth, to help everyone have more choices and reference value when choosing a laser welding machine. With its high degree of controllability and process flexibility, laser welding machines achieve full welding coverage from thin plates to thick plate materials. By scientifically configuring equipment parameters and optimizing the welding process, laser welding technology can not only meet the welding needs of materials of different thicknesses, but also ensure the formation of high-quality welds, thus being widely used in automobiles, precision hardware, 3C electronics, aerospace, advertising lighting, etc. It has been widely used in other industrial fields.
