Introduction to the application of laser bevel cutting machine in manufacturing industry


In manufacturing and processing, many parts and components will have a certain angle of groove processing due to the design and structure requirements, which is indispensable in automobile manufacturing, industrial and agricultural machinery, and ships and ships. The processing of the groove is mainly for the next welding process. The groove to be welded is processed and assembled into a groove of a certain geometric shape in the weldment to obtain a weld with full penetration in the welding thickness.


The groove processing mostly uses flame, plasma and other processing methods. The common groove forms include V-shaped groove, U-shaped groove, X-shaped groove and Y-shaped groove. These processing methods will produce a deeper cut when cutting the groove, and it is easy to cause the groove to be unfused if it is not eliminated before welding. Generally, such dents must be processed if they exceed 3mm. In important locations, only grinding can be used to eliminate them. Repair welding is not allowed. If there are defects, the follow-up processing is very troublesome. At the same time, flame and plasma processing belong to high-calorie processing, and metal plates are prone to thermal deformation. After the groove is processed, an inverse deformation process is required, which is another major difficulty.



Fiber laser cutting machine is a new type of bevel processing method with the smallest thermal deformation and the best cut quality. The laser bevel cutting machine can process steel plates within 20mm and can complete V, X, Y and other forms at one time. Compared with traditional flame, plasma groove processing and laser groove cutting greatly improve the processing efficiency, ensure the quality of the groove, and save materials. For example, laser groove cutting is used in shipbuilding to process low-alloy steel T-shaped members, which can greatly reduce the weight while ensuring the stability of the ship.


With the advancement of major projects such as railway construction, highway construction, water conservancy construction, hydropower construction, energy, mining construction, and construction industry in China, the demand for construction machinery market has increased year by year, and bevel laser cutting machines have become popular in construction machinery industry. Especially with the enlargement of construction machinery, it is necessary to adopt higher-strength low-alloy steel structure. In order to ensure the good toughness of welded joints, it is necessary to reasonably control the welding heat effect and avoid the embrittlement of welded joints. The traditional thermal processing method can no longer adapt to the current forming of high-strength steel plates, and the introduction of laser bevel cutting machines in the engineering machinery industry is a suitable choice.
