Laser Welding Machine Energy Attenuation Reasons
Analysis of the reasons for the weakening of the Laser Welding Machine provided by the China Laser Marking Machine Manufacturer:
1. Main light path laser offset processing method: adjust the main light path full-reverse and semi-reflex film, use paper to check and round the spot
2, focusing lens damage or pollution treatment: replace or clean the focus lens and protective lens.
3. The laser does not output from the center of the copper nozzle below the focusing head. The method is to adjust the 45-degree reflection diaphragm to make the laser output from the center of the nozzle.
4, the laser cavity diaphragm damage or pollution treatment: replace or clean the resonant cavity reflective diaphragm.
5, the shutter does not completely open the treatment method: check and add lubricant on the shutter connection, so that the connector can be mechanically smooth
6. The service life of the xenon lamp has reached the treatment method: check and clean the old lamp or replace it with a new one.
7. Cooling water pollution or long-term replacement of cooling water: replace the cooling water and clean the filter glass tube and the xenon lamp
8. The defocusing amount of the focusing mirror is too large. The method of adjusting the defocusing amount to the position close to the focus (but no spatter can be generated)
9. The protective gas is opened too much. Adjust the gas flow of the protective gas.
