In manufacturing and processing, many parts will have a certain Angle of beveling processing because of the design structure needs, which is essential in automobile manufacturing, industrial and agricultural machinery and ships. Machining groove is mainly for the next welding process, in the welding parts to be processed and assembled into a certain geometric shape of the groove, can get the welding thickness of all welded weld.
Beveling processing adopts flame, plasma and other processing methods, the common form of beveling is V groove, U groove, X groove and Y groove. These processing methods will produce deeper cut marks when cutting the groove, if not eliminated before welding is easy to cause the groove is not fused. Generally, this kind of dent more than 3mm must be dealt with, in the important position, can only be polished to eliminate, not allowed to repair welding, defects when the follow-up processing is very troublesome. At the same time, flame and plasma processing belongs to high heat processing, metal plate is easy to produce thermal deformation, after the groove processing also need to carry out anti-deformation process, which is a big difficulty.
Laser processing is a new groove processing method with minimum thermal deformation and best notch quality. Laser groove cutting machine processes steel plate within 20mm, and can complete V, X, Y and other forms of groove at one time. Compared with traditional flame and plasma groove processing, laser groove cutting greatly improves the processing efficiency, ensures the quality of the groove, and also saves materials. For example, laser bevel cutting is used in ship manufacturing to process T-shaped components of low-alloy steel, which can greatly reduce the weight while ensuring the stability of the ship.
Along with the major project of railway construction, highway construction, water conservancy construction, hydropower construction, energy, mine construction, construction industry to push, our country construction machinery market demand rises year by year, bevel laser cutting machine is widely used in our country construction machinery industry. Especially with the large scale of construction machinery, it is necessary to use higher strength low alloy high strength steel structure. In order to ensure the good toughness of welded joints, it is necessary to reasonably control the welding heat action and avoid the embrittlement of welded joints. The traditional hot working method can no longer adapt to the forming of the current high strength steel plate, so the introduction of laser bevel cutting machine in the construction machinery industry is a suitable choice.
