The cutting head of laser cutting machine is used in a very bad environment, so in order to protect the inner light path and the core parts, especially the expensive parts such as collimating and focusing lenses, the cutting head must be equipped with up and down protecting lenses, during the cutting process, the dust and spatter on the surface of the workpiece will cause serious damage to the focusing mirror if it enters the cutting head, and the protective mirror can block these dust and spatter …

The laser cutting process requires two steps: perforation and cutting. Only when the perforating effect is good and stable can the cutting effect be obtained. The phenomenon of exploding holes is easy to appear when the thick plate is perforated, resulting in cutting instability, lens, and nozzle damage. Therefore, in order to stabilize the processing to obtain a good sample effect, excellent piercing is the first step …

In the process of laser cutting stainless steel, various small problems are often encountered, such as a large number of unremovable adhesions on the surface after perforation, occasional incomplete cutting during initial cutting, and slagging when cutting small contours or sharp corners. We will analyze the causes of these problems and give the corresponding solutions …

As one of the two basic modes of laser welding, laser deep penetration welding is applied more and more widely. In order to obtain the higher benefit of laser deep penetration welding, the main influence factors of this welding method are summarized, including laser power density, welding speed, focus position, shielding gas, assembly gap of workpiece joints, material nature and other aspects to help user seeks advantages and avoid disadvantages and make the best use of handheld laser welder …

In the daily fiber laser machine batch processing of steel plates, the processing quality will deteriorate after a period of continuous processing. We discuss the causes and solutions on the premise that the processing parameter settings have been optimized …

Due to the excellent flexibility of optical fiber, the laser can be designed to be quite small and flexible, compact, easy system integration, cost-effective. Fiber laser has been widely used in laser cutting, laser welding, laser cleaning, and other industrial fields …

Before turning on the fiber laser cutting machine, a coaxial test must be done to ensure that the laser cutting machine can operate normally and avoid abnormal startup due to errors. The coaxial test mainly refers to adjusting the coaxiality of the laser head nozzle outlet hole and the laser beam. It is necessary to ensure that the nozzle outlet and the laser beam are on the same straight line. Seen from the cross-section, they are concentric circles …

In the application of molds, signs, hardware fittings, billboards, and other products, the traditional corrosion process not only brings about environmental pollution but also low efficiency. Compared with the traditional metal deep-carving method, laser metal deep marking has the advantages of no pollution, high precision and flexible marking content, which can meet the requirements of complex marking technology …

Welding defect is any defect that impairs the usefulness of the weldment. There are many kinds of welding defects, such as crack, deformation, inclusion, and incomplete penetration. It is well known that the correct use of welding shielding gas is also an important factor affecting the weld formation and performance. Selecting the best welding shielding gas is the way to improve the welding quality and efficiency …

It is very important to extend the service life of the co2 laser cutting machine as far as possible in order to save production costs and gain more benefits. The stable and normal operation of the laser machine can not be separated from routine maintenance …
