With the continuous development of science and technology, laser cutting technology, as an efficient and high-precision processing method, has been widely used in various industries. Among them, high-strength structural steel plate is one of the important application fields of laser cutting technology. High-strength structural steel plate has the characteristics of high strength, high rigidity and high durability, and is widely used in bridges, construction, automobiles, ships and other fields. Laser cutting technology can achieve high-precision and high-efficiency processing, so it has been widely used in the processing of high-strength structural steel plates.
The process of laser cutting high-strength structural steel plate is mainly through the laser beam focusing, and then a quick scan on the high-strength structural steel plate, so that the steel plate is instantly melted and a cutting joint is formed. In this process, parameters such as the power, speed, and focal length of the laser beam will affect the cutting quality and efficiency. At the same time, the mechanical properties, chemical composition, thickness and other factors of the high-strength structural steel plate itself will also have an impact on the cutting effect.
In order to achieve high-quality, high-efficiency laser cutting, a series of process measures need to be taken. First of all, it is necessary to choose the appropriate cutting parameters, such as laser power, cutting speed, gas pressure, etc. These parameters need to be reasonably adjusted according to the thickness, material, cutting requirements and other factors of the steel plate. Secondly, it is necessary to ensure the surface quality of the steel plate and remove the oil, rust and other impurities on the surface of the steel plate to improve the cutting quality and efficiency. In addition, it is necessary to use an appropriate cutting head and focusing mirror to ensure the focusing effect and stability of the laser beam.
In the process of laser cutting high-strength structural steel plates, there are also some technical problems that may arise. For example, due to reasons such as the thickness of the steel plate or the insufficient laser power, there may be a phenomenon that the cut is not transparent or the cut gap is too wide. In this case, it is necessary to adjust the cutting parameters or change the laser according to the actual situation. In addition, due to the low thermal conductivity of high-strength structural steel plates, it is easy to produce thermal deformation or ablation during the cutting process. In order to solve these problems, measures such as water cooling or local ventilation can be used to reduce the temperature of the steel plate.
Laser cutting of high-strength structural steel plates has the following advantages:
1.High precision: The focusing diameter of the laser beam is generally between a few microns and hundreds of microns, so high-precision machining of high-strength structural steel plates can be realized.
2.Fast speed: The processing speed of laser cutting is very fast, and a large area of cutting tasks can be completed in a short time.
3.Low thermal impact: During the laser cutting process, the thermal impact on the surrounding materials is very small due to the high concentration of the energy of the laser beam, which can effectively reduce problems such as thermal deformation and cracks.
4.Incision***The incision of laser cutting is smooth and neat, which can reduce the workload of subsequent processing and handling.
5.High degree of automation: Laser cutting can achieve automatic processing, improve production efficiency and processing quality.
In practical applications, laser cutting of high-strength structural steel plates also needs to pay attention to the following points:
1.Safety protection: The laser cutting process will produce strong arc light and smoke, so it is necessary to take effective safety protection measures, such as wearing protective glasses and dust masks.
2.Material management: The quality of high-strength structural steel plates has a significant impact on cutting quality and efficiency, so quality inspection and control of materials is required.
3.Equipment maintenance: Laser cutting equipment needs regular maintenance and maintenance to ensure the stability and reliability of the equipment.
4.Environmental control: The environment needs to be kept clean and dry during the laser cutting process to avoid adverse effects on equipment and materials.
5.Technical training: Operators need to undergo professional technical training to master the principles and operation skills of laser cutting technology to ensure processing quality and safety.
In a word, laser cutting of high-strength structural steel plate is an efficient and high-precision processing method, which has a wide range of application prospects and market demand. In practical application, it is necessary to select appropriate process measures and technical solutions according to the specific situation to ensure the quality and efficiency of processing. At the same time, it is also necessary to strengthen equipment maintenance and technical training, improve the skill level and sense of responsibility of operators, so as to achieve safer, efficient and high-quality processing and production.
