Popular science: common problems and solutions of laser welding machine

Laser welding machine is very widely used, it can weld most metal materials, but it is also a more complex equipment, simple operation does not mean that there will be no problems in the use of mechanical equipment, more or less may be due to improper operation, or new materials will not adjust parameters and other reasons to cause the machine to shut down. Lansu Laser has sorted out the following common problems and solutions for you, which can be used as a reference. Of course, if you really encounter problems that cannot be solved, instead of looking for information online, it is recommended that you find the original equipment supplier to check the problem.

1, laser welding machine lamp has been lit, automatic state does not light, manual state light. Solution: Check whether the plug-in is loose; Whether the internal and external control modes are properly adjusted.z

2. The weld is very black when welding. Solution: Nitrogen is not on, as long as the nitrogen can be solved. The airflow direction of the protection gas is wrong, and the airflow direction of the protection gas should be opposite to the movement direction of the workpiece.

3, laser welding machine welding cracks:

The cooling speed of the workpiece is too fast, and the temperature of the cooling water should be adjusted on the fixture to increase the temperature of the water.

When the workpiece is too large or has burrs, the processing accuracy of the workpiece should be improved.

The workpiece has not been cleaned. In this case, the workpiece needs to be cleaned again.

The flow of the protective gas is too large, which can be solved by reducing the flow of the protective gas.

4, the output power is unstable. Solution: When the laser power is unstable, it will cause the laser welding machine to not work normally, and there will be various failures. At this time, check whether the voltage of the laser generator is stable, if it is not stable, you need to check and repair the laser generator.

5, welding splash. After laser welding is completed, there are many metal particles on the surface of the material or workpiece, which are attached to the surface of the material or workpiece. Cause: The surface of the material or workpiece is not cleaned, there are oil stains or pollutants, and it may also be caused by volatilization of the galvanized layer. Solution: Clean the material or workpiece before laser welding.

Laser welding is a kind of welding method with high efficiency and high precision using laser beam with high energy density as heat source. Today, laser welding machines have been widely used in various industries, such as: 3C electronics, automobile manufacturing, hardware tools, building materials, aerospace and other industrial manufacturing fields. Only by fully understanding this equipment, will not be helpless when there is a problem, in order to better play the value of laser welding!
