-
What should I do if the laser welding is unstable or the laser cleaning effect is not satisfactory?
Laser welding should check the material surface, joint gap, protective gas, focus, swing width, wire feeding and moving speed; laser cleaning should check the power, frequency, scanning speed, spot overlap and pollution layer thickness. It is recommended to start testing with lower energy and gradually increase parameters to avoid damaging the substrate.
-
What should I do if the positioning accuracy of the equipment decreases or there is abnormal noise during operation?
Check whether there are any debris on the guide rails and racks, whether the lubrication is normal, whether the transmission parts are loose, and whether the servo system alarms. Do not continue production through repeated forced resets. The mechanical accuracy and transmission clearance should be checked by professionals.
-
What should I do if the chiller has a high temperature, low flow or water shortage alarm?
The load should be reduced or the light output should be stopped immediately, and the water level, filter, pipeline, circulation pump, ambient temperature and water inlet and outlet direction should be checked. Do not continue high-power processing when the cooling system is abnormal.
-
Why do protective lenses often burn out?
Common causes include compressed air containing oil or water, severe splashing from the nozzle, poor sealing, contamination of lens installation and unreasonable perforation parameters. When the lens is continuously replaced but is still frequently burned, processing should be stopped and the air path and cutting head seal should be checked.
-
What should I do if the cutting results at different locations on the same board are inconsistent?
Check plate flatness, table support, focus alignment, nozzle concentricity, gas pressure and protective lens status. If the difference has a fixed direction, the mechanical accuracy and cutting head follow-up status should also be checked.
-
What should I do if there are holes or a lot of spatter during piercing?
The piercing power, piercing time, focus, nozzle height and plate surface condition should be checked. When processing medium and thick plates, graded perforation can be used and the cooling time can be appropriately increased to avoid inputting too much energy at one time.
-
What is the reason why the cutting section is rough or has obvious streaks?
It may be related to too fast or too slow speed, focus position, gas purity, nozzle status, lens contamination and material surface quality. It is recommended to confirm the consumable and gas status first, and then conduct a small-scale gradient test cutting near the current speed.
-
What should I do if there is slag hanging on the bottom of the workpiece?
You can check the cutting speed, focus position, auxiliary gas pressure, nozzle diameter and nozzle concentricity. Only adjust one parameter at a time and compare samples to avoid changing multiple parameters at the same time without being able to determine the cause.
-
What is the reason for failure to cut through during cutting?
Common reasons include inappropriate power or speed settings, focus position deviation, insufficient gas pressure, nozzle damage, protective lens contamination, material thickness out of tolerance or actual light output power reduction. It is recommended to start with basic items such as nozzles, lenses, gases and focus.
-
What should I do if the device does not emit light after it is turned on?
First check whether there are alarms in emergency stop buttons, safety door interlocks, chillers, lasers, control systems and gases. Do not disassemble the laser or cutting head by yourself. Record the alarm code and contact technicians for processing.
-
Can the handheld laser welding machine and laser cleaning machine be turned on and used directly?
Can't. Operators must receive professional training, set up a controlled work area, and be equipped with corresponding laser protective equipment and smoke exhaust facilities according to risk assessment. It is strictly prohibited to point the laser beam at people, non-target objects or highly reflective surfaces.
-
How to maintain the guide rail, rack and transmission system?
Guide rails, racks and related transmission components should be cleaned and lubricated regularly according to the equipment maintenance manual, and checked for abnormal noise, looseness and abnormal wear. Do not use lubricating grease that does not meet the requirements.
