Fiber laser cutting machine itself is a kind of machine produced by laser, which has better effect during use, but many people may not understand its working principle. This is the effect of using laser release. It is not easy to cause more problems during use. First, use the light spot to irradiate it directly on the metal plate to achieve the cutting effect.
The fiber laser cutting machine adopts the form of high voltage, which can play the role of cutting, and it is also a popular product in recent years. The optical fiber laser cutting machine can effectively achieve the effect of comprehensive replacement, and has a high probability of appearing in the current market, which can achieve better effects and also has the characteristics of basic development.
Fiber laser cutting machine mainly uses glass fiber as the medium to achieve rapid effect and form high density. In the daily operation process, it is not easy to have more problems, and the cutting effect can be achieved even in a high temperature environment.
We all know that metal fiber laser cutting machine equipment can be widely used in various industries, whether in the hydropower industry or in various construction industries. Therefore, for everyone, the industry use of metal fiber laser cutting machine equipment is not limited, and even the requirements for the workpiece are not very high. The equipment of the laser cutting machine can be used to cut only metal sheets before. But now with the development of the production industry, metal fiber laser cutting machines can cut some non-metallic plates.
If you use metal fiber laser cutting machine equipment, I do not recommend you to buy it, because the cost of a piece of equipment is very expensive, but if it is mass production, then metal fiber laser cutting machine equipment can greatly improve production efficiency. In addition, it can free up workers' hands and control costs to a very low-level producer.
Laser welding is one of the important applications of laser processing technology. The laser welding machine is applied to the heater. The laser radiation heats the surface of the workpiece. By controlling the width, energy, power density and repetition frequency of the laser pulse, the surface heat is diffused through internal heat transfer and the workpiece is melted to form a specific melt. Pool. Because of its unique advantages, it has been successfully applied to the welding of tiny parts.
The emergence of high-power CO2 lasers and high-power YAG lasers opened up a new field of laser welding. Deep penetration welding based on the keyhole effect has been widely used in machinery, automobiles, steel and other industries.
Features of laser welding machine
Laser welding can be used to weld inaccessible parts. There is great flexibility for non-contact long-distance welding. In YAG laser technology, optical fiber transmission technology has been widely used, making laser welding technology more widely used. The laser beam is easy to be divided in time and space, and it can be processed with multiple beams at the same time, which provides conditions for more precise welding. For example, it can be used in devices that do not allow welding pollution and deformation, such as thick plates of automobile bodies, automobile parts, lithium batteries, pacemakers, and sealed relays.
Principle of laser welding
Laser welding technology has the function of purifying the molten pool and can purify the weld metal. Suitable for welding the same metal material with different metal materials. High-energy laser welding is especially suitable for welding metals with high melting point, high reflectivity, high thermal conductivity, and large differences in physical properties.
Advantages of laser welding
The main advantages of laser welding are high speed, deep penetration and small deformation. Can be welded at room temperature or under special conditions.
The laser beam does not move when passing through the electromagnetic field. The laser can be welded in air and certain gas environments, and it can also weld glass or transparent materials. After the laser is focused, the power density is high, the aspect ratio can reach 5:1, and the highest can reach 10:1. It can weld refractory materials such as titanium and quartz with good welding effect. For example, when copper and Hyun are welded together, the pass rate can reach 100%. It can also be used for micro welding.
After focusing, the laser beam can obtain a small spot, which can be accurately positioned. It can be applied to the assembly and welding of micro-components in large-scale automated production such as integrated circuit leads, surface float wires, and picture tube electron gun assembly. Due to the laser welding, the production efficiency is high, the heat-affected area is small, and the solder joints are pollution-free.
