As one of the important materials for construction work, aluminum scaffolds will naturally have high quality requirements. Because the quality of aluminum scaffolding not only concerns the safety of workers, but also the quality and cost of the project, so aluminum scaffolding With the development of technology, it has been continuously improved and improved. The aluminum scaffolding surface laser processing method is a good way.

 

At present, domestic laser heat treatment has been applied to production practices. For example, GCrl5 steel punching dies are laser-strengthened to increase their service life by a factor of 2. After the silicon steel die has been treated, the service life is increased by 10 times. Therefore, after the aluminum heat treatment with laser heat treatment, it will also have a significant effect.

 

Because of the high power density of the laser spot, it can be accurately guided to different parts of the surface of the aluminum scaffold fastener mold, or scanned in a certain area; at the same time, the surface of the aluminum scaffold fastener can also be treated locally, and the power density can be accurately controlled. The energy of the input mold is small, the deformation of the mold is small, the surface after processing can be no longer machined or only a small amount of machining.

 

When the laser is applied to the surface of the aluminum scaffold fastener, the absorption coefficient of the metal to the laser is as high as 105 to 106 cm-1, and the absorption process takes place in a 0.01 to 0.1 μm thick layer on the surface thereof. The depth of the laser surface treatment of fasteners depends on the thermal diffusion distance from the surface to the inside. Its value is small and it is easy to control. In addition, the laser is not chemically contaminated, so it is easier to transmit, switch, and automatically control.

 

This is a series of advantages brought by the aluminum scaffolding laser surface treatment technology, and it actually means that a certain power density laser beam is irradiated onto the working surface of the aluminum alloy scaffold at a certain scanning speed, and in a very short time, The treated surface sharply heats up due to the absorption of laser energy.

 

When the laser beam is removed, the surface of the aluminum scaffold to be processed is rapidly cooled by the substrate itself to undergo physical and chemical changes, thereby forming a surface layer with certain properties, and improving the hardness, strength, and wear resistance of the surface of the material. , corrosion resistance and high temperature performance, can significantly improve the quality of products, improve the life of the mold, and achieve good economic benefits. http://www.eg-scaffold.com/
