How to ensure the welding quality and effect of laser welding machine?

In the actual laser welding machine welding production process, there will also be various problems for various reasons. How to find out the cause of the problem and how to solve the quality problem is a very important link in the production process management.

First, check the welding quality. It is very important to check the quality of machined parts. There are generally two methods: visual inspection and destructive inspection. The appearance inspection is to judge whether the welding products are qualified according to their rich work experience, but the destructive inspection of the workpiece is more scientific. Yes, we can tear up the welding base metal for confirmation.
Secondly, after the inspection, of course, analyze the reasons for these poor quality according to the phenomenon, and then check the parts of the laser welding machine in turn to see if it is caused by the focusing lens of the laser welding machine. Laser welding machine or loose parts.

Finally, strengthen the management of laser welding machine. During the welding process, the welding pressure shall be frequently detected to ensure the stability of the welding pressure, and the laser welding head shall be frequently inspected. The second is to strengthen the control of current to avoid power supply voltage fluctuation and current overheating caused by laser welding overload action. Then check the thickness and processing energy of the workpiece to avoid overload welding.

Generally speaking, the factors affecting the effect of laser welding can be summarized into the following three choices: the choice of welding materials, the choice of laser welding machine and the choice of processing table. Therefore, we can start from these three points. The selection of appropriate laser welding machine and appropriate processing materials is the main factor to ensure normal welding.
