How to ensure the welding quality of laser welding machine?

In the actual welding production process of laser welding machine, various problems will appear due to 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. 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. Visual inspection means that workers judge whether the welding products are qualified according to their rich work experience, but the destructive inspection of the workpiece is scientific. We can tear up the welding base metal for confirmation.

Secondly, after the inspection, of course, analyze the causes of poor quality according to the phenomenon, and then check the parts of the laser welding machine in turn to see whether the focusing lens or parts of the laser welding machine are loose.
Finally, strengthen the management of laser welding machine. During the use of the welding machine, the welding pressure shall be tested frequently to ensure the stability of the welding pressure, and the laser welding head shall be checked frequently. The second is to strengthen the control of current to avoid the current overheating caused by the fluctuation of power supply and voltage and the overload effect of laser welding. Then check the thickness and processing energy of the workpiece to avoid welding overload.

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 workbench. 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.

Long time full load of fiber laser welding is harmful to the equipment;
1. Main components: laser power supply: full power optical fiber laser welding machine is like a car running 120 yards for a long time, which is easy to cause the aging of laser power supply (mainly providing power supply) and related electronic and optical components, and shorten the service life of components.
2. Main components: laser xenon lamp and crystal: the consumption of consumables of fiber laser welding machine is growing rapidly. For example, the xenon lamp normally emits light for 1 million times, which will be reduced to hundreds of thousands of times after long-time full load operation. When long-time full load operation, the influence of temperature rise and damage of lens coating surface will be intensified, which is also easy to lead to pollution and fracture.
3. Main components: laser chiller: the high-frequency start and stop of the chiller of the optical fiber laser welding machine is very important to its internal compressor and main components, which shortens the service life of the chiller.
