Fiber laser welding machine In order to ensure that the laser is always in normal working condition, after two weeks of continuous work or after the end of the application for some time, the first should be YAG before starting the bar, dielectric film and lens protection glass components in the optical path inspection, The optical components without dust pollution, mildew and other abnormal phenomena, such phenomena should be dealt with in time to ensure that the optical components will not be destroyed under strong laser irradiation.
Equipment operators can often use black paper to check the laser output spot, if the uneven spot or the phenomenon of energy decreased, should be timely fiber laser welding machine to adjust the resonant cavity to ensure that the laser output beam quality. The typical spot image is as follows: After adjusting the spot is not adjusted good spot Laser resonant adjustment Notice: This product is 4 types of laser equipment, direct high-intensity laser light on the human skin can produce severe light damage, in particular, will make the eyes Blinding, debugging operators must have the knowledge of laser safety, the work must wear 1.064mm wavelength for the special laser protective glasses.
The purity of cooling water is the key to ensure the laser output efficiency and the lifetime of the laser cavity assembly. In the application, the conductivity of the circulating water in the fiber laser welding machine should be checked once a week to ensure its conductivity is 30MWcm, and the internal circulation must be changed once per month. Of the deionized water, the new injection of pure water conductivity of 32MWcm. Always pay attention to look at the cooling system in the ion exchange column color changes, once found in the replacement column resin color into dark brown or black, should immediately change the resin.
Note: When the strong laser direct exposure to wood and other flammable products will produce open flame, debugging process should be placed in the laser output optical path of a good absorption of the black metal material as a beam terminator, to avoid causing a fire. Note: Fiber laser welding machine transfers must be carried out by specially trained personnel, or because of fiber laser welding machine misalignment or misalignment caused by the destruction of other components on the optical path. The procedure for adjusting the laser resonator is as follows: Checking the reference light source The red semiconductor laser is the reference for all the optical paths, and must be first checked for correctness. Use a simple height gauge to check whether the red light is parallel to the top surface of the optical guide rail and is on the center line between the two guide rails of the optical bench. If there is a deviation, it can be adjusted by six fastening screws. After adjustment, pay attention to check again after all fastening screws can be fully tightened.
