Laser welding belongs to melting welding, which uses the laser beam as the energy source to impact on the weldment joint. Laser welding is non-contact welding, which does not need to be pressurized during operation, but inert gas is required to prevent oxidation of the molten pool, and filler metal is occasionally used. Laser welding…
It is obvious that people want to make money with laser cutting machines. Many people believe that increasing the power of lasers will increase their income – sometimes it is, but sometimes it is not. If we consider how increasing power will affect income, then we should discuss this issue in detail. When the power…
Laser cladding technology belongs to the additive manufacturing technology of metal and its composites, and is an important supporting technology of laser strengthening manufacturing, laser remanufacturing and laser 3D manufacturing technology. In addition, laser cladding technology is an additive manufacturing technology that can meet the requirements of the integration of forming and forming. It can…
Using closely focused ultrashort pulses, almost all transparent materials can be transmitted. Weldable materials include polymers, dielectrics and even ceramics. In this method, the two materials to be welded are placed closely together; The material placed on the top must be transparent to the laser, so that the laser can pass through the top material. Focus…
At present, there are two main methods for cutting metal plates: plasma cutting and laser cutting. Plasma cutting can be traced back to the 1950s, when it emerged as a substitute for flame cutting. The working principle of plasma cutting is: spray the overheated ionized gas (plasma) from the nozzle to the workpiece at high…
Compared with conventional welding methods, laser welding is a precision welding method with multiple functions, strong adaptability and high reliability, and is easy to realize automation. Due to the high power density of the laser and the low heat input during welding, on the basis of ensuring the penetration depth, the welding heat affected zone…
As China’s relevant legislation and regulations become more and more strict, environmental protection has become a very important consideration in industrial processing. It is difficult for traditional cleaning technology to meet the high requirements of environmental protection. As a new, green and efficient cleaning method, laser cleaning technology has gradually been widely concerned by the…
A conventional fiber laser cutter laser consists of three parts: working material, pump source and optical resonator. 1.Working substance Working material is the material basis of laser generation, the core part of laser, and the material system used to realize particle number inversion and generate stimulated radiation. There are two ways to classify working materials:…
Laser cladding technology is a surface modification technology and equipment maintenance technology with high-tech content. It is a combination of material preparation and surface configuration. It is one of the key supporting technologies of green remanufacturing technology. It is a high-tech industry in line with the national sustainable development strategy. Its research and development has…
In recent years, with the rapid development and upgrading of electronic, electrical and digital products, more and more important parts of electronic products are produced towards the trend of miniaturization, and the demand for high-precision processing methods is increasing. As a new technology of precision welding technology, laser tin welding technology has ushered in rapid…
