At present, in the manufacturing industry, the common processing mode has changed from traditional contact processing to laser non-contact processing. The common equipment in laser processing is laser welding machine. Because handheld metal steel fiber laser welding machine has significant advantages such as high welding efficiency, small weld and small spot, it is deeply loved by many customers. If it is used more, there will be more corresponding faults.
Of course, any machine has the possibility of failure. In order to make the laser welding machine work better, reduce the number of failures and increase its work efficiency, we must understand the problems that should be paid attention to in its operation and the treatment methods of failures. This article mainly explains the common fault handling methods of laser welding machine:
1) If the flow of shielding gas is too large, it can be solved by reducing the flow of shielding gas.
2) If the cooling speed of the work piece is too fast, adjust the temperature of the cooling water on the fixture to increase the water temperature.
3) The work piece is not cleaned completely. In this case, the work piece needs to be cleaned again.
4) If the fit clearance between work pieces is too large or there are burrs, the machining accuracy of work pieces should be improved.
1) If the laser energy is not enough, it can be solved by increasing the pulse width and current.
2) If the defocus amount of the focusing lens is incorrect, adjust the defocus amount to close to the focus position (but there shall be no spatter).
1) If the cooling water is polluted or has not been replaced for a long time, it can be solved by replacing the cooling water and cleaning the UV filter glass tube and xenon lamp.
2) If the focusing lens or the resonator diaphragm of the laser is damaged or contaminated, it should be replaced or cleaned in time.
3) The laser offset of the main optical path, adjust the full reflection and half reflection diaphragm of the main optical path, and use the image paper to check and round the spot.
4) The laser is not output from the center of the copper gas nozzle under the focusing head. Adjust the 45 degree reflection diaphragm to output the laser from the center of the gas nozzle.
5) If the shutter is not fully opened, check and add lubricating oil on the shutter connector to make the connector mechanically smooth.
The above is the treatment of three common types of faults of laser welding machine. I hope it can be helpful to you.
