1. More environmentally friendly: No need to use any chemical agents or cleaning liquids, the cleaned waste is basically solid powder, small in size, easy to store, recyclable, non photochemical reaction, and does not produce pollution.2. Good effect: Laser cleaning is non abrasive, non-contact, and has no thermal effect. It does not generate mec...

Sometimes when using a laser marking machine to print something, it may not be obvious. What is the reason for this? In fact, there are many reasons why the laser marking machine may not produce obvious results during use, such as the power of the laser, the focal length, and the material used. We can first check the focal length of the laser marki...

Defects in copper alloy laser welding1. Welding stressThe coefficient of linear expansion and shrinkage of copper are also relatively large. The coefficient of linear expansion of copper is 15% higher than that of iron, and the shrinkage rate is more than twice that of iron. In addition, copper and copper alloys have strong thermal conductivity, wh...

The process flow of laser cutting is relatively simple, and the laser cutting path and parameter program are set in advance according to different products. Generally, holes are cut first, and then edges are cut. After the first piece debugging is qualified, cutting production can be directly carried out. However, it is not easy to cut the best qua...
