As a welding method, laser welding machine is used in all walks of life. In the process of using the laser welding machine, there will always be some large and small faults, the following is a summary of the common faults and solutions of the laser welding machine. The screen of the laser welding machine is in a black screen state, the screen of the laser welding machine has a problem, find the cause in time, repair or replace the screen.
Laser welding machine
Laser welding machine welding depth is not enough, laser energy is not enough, can improve the pulse width, improve the current to solve. If the defocus of the focusing mirror is not correct, the defocus should be adjusted to the position near the focus (but there should be no splash). Laser welding machine in the use of the host is in a shaking state, laser welding machine under the foot base is not fixed, or only a part of the fixed solution: the base of the laser welding machine can be fixed.
The laser welding machine cracks when welding the workpiece, and the flow rate of the protective gas is too large, which can be reduced to solve the problem. If the cooling speed of the workpiece is too fast, the temperature of the cooling water on the fixture should be adjusted to increase the water temperature. The workpiece is not cleaned. In this case, the workpiece needs to be cleaned again. If the matching gap between the workpiece is too large or there are burrs, the processing accuracy of the workpiece should be improved. The laser welding machine reduces the flame when welding.
The main optical path laser offset, the solution: adjust the main optical path full reverse and semi-reverse diaphragm, using the image paper to check and adjust the spot. Cooling water pollution or long-term no replacement of cooling water, the solution: replace the cooling water and clean the filter UV glass tube and xenon lamp.
The focusing lens or the resonator diaphragm of the laser is damaged or contaminated, the solution is to replace or clean the focusing lens and the resonator reflection diaphragm. The laser is not output from the center of the copper nozzle under the focusing head, the solution: adjust the 45 degree reflecting diaphragm so that the laser is output from the center of the nozzle.
The light brake does not fully spring open, the solution: check and add lubricating oil on the light brake connector to make the connector mechanically smooth. The protection gas is opened too much, the solution: adjust the gas flow of the protection gas.
The welding seam of the laser welding machine is very black, the airflow direction of the protection gas is wrong, the solution: make the airflow direction of the protection gas and the direction of the workpiece movement, nitrogen is not open, the solution. Turn on the nitrogen.
