Why is laser cleaning more efficient than ultrasound?

Image
The efficiency of laser cleaning is higher than that of ultrasonic cleaning‌ , mainly due to the technical characteristics and advantages of laser cleaning. Laser cleaning uses the photothermal effect of laser to produce changes in the thermal expansion coefficient by irradiating the surface of the substrate so that dirt is peeled off from the surface of the substrate. During this process, the laser used by the laser cleaning machine will produce tens of millions of oscillations during cleaning, and the stripped dirt will be shattered by the laser. By adjusting the appropriate cleaning parameters, non-damaging cleaning of the substrate can be achieved. This cleaning method can not only achieve damage-free cleaning, but also because the laser can be transmitted through optical fibers and cooperated with robot hands and robots, it can easily achieve long-distance operations and can clean parts that are difficult to reach with traditional methods. These characteristics give laser cleaning...

Advantages of single-mode and multi-mode continuous green light applications

Image
1.  Advantages of single-mode continuous green light application:   (1) Compared with multi-mode laser , single-mode has greater focal depth and melting depth. Under the same parameters, the aspect ratio of a single-mode laser is 7.6, while that of a multi-mode laser is 1.05. Therefore, single-mode laser has stronger penetration than multi-mode laser   (2) Higher energy density and a larger process window can be achieved when welding products with the same power   (3) Since single-mode has a large aspect ratio, its welding precision is much higher than that of multi-mode. It does not require a large laser power to achieve precision welding, and the heat effect and deformation after welding are small   (4) Since the focused spot is smaller, more delicate welding can be obtained and higher processing accuracy can be achieved   (5) Better beam quality, a longer focal length field lens can be used in actual use, and the processing format is larger; this advanta...

How to improve the welding quality of handheld laser welding machine

Image
How to improve the welding quality of handheld laser welding machines? 8 steps can be improved, such as laser power adjustment, welding speed, focal length check, welding gun tilt angle, swing frequency and swing width, filler wire selection, operator training, and daily inspection of protective lenses. These steps can not only improve welding quality but also extend the service life of laser welding machines.   1.  Power adjustment: During welding, set the appropriate laser power to obtain the best welding effect. Based on different materials and thicknesses, choose the appropriate power. If the laser power is too high, it may melt too quickly, causing dents or undercuts. If the power is higher, the welding will be successful. For example, the aluminum oxide on the surface of aluminum alloy has a high melting point and high reflectivity. If the laser power is too low, most of the laser will be reflected away. Therefore, when welding ordinary aluminum alloys, it is recommended...

CO2 laser processing material selection guide and precautions

Image
Various industries widely praise Lasers as "universal processing tools", but there are still many things to pay attention to in the selection of laser processing materials, so more care should be taken in material selection.   Wood is the most commonly used and easiest material to process. CO2 laser processing can accurately cut, engrave, and punch wood, producing clear and smooth edges.   When cutting wood, the power and speed of the machine need to be adjusted according to the thickness of the wood, otherwise it will not be cut through. For details, please refer to the parameters of the laser cutting machine, or contact Ruida Technology's technical service.   In addition, wood can also be engraved. Customized pencil names that have been very popular on the Internet in the past two years use laser engraving technology. CO2 laser processing has no requirements for the choice of wood, and any wood can be used. Paper materials are readily available in our daily lives, and c...

Introduction to fiber lasers 2

Image
A fiber laser is a type of fiber that uses doped with rare earth elements as a laser medium. It activates the fiber to generate and amplify laser light. This laser device has many unique advantages that make it widely popular in the medical and industrial fields. The core part of the fiber laser is an optical fiber doped with rare earth elements (such as ytterbium-doped fiber and erbium-doped fiber). When the pump light source (usually a diode laser) enters the optical fiber through a coupler, the rare earth element is excited and generates laser light through stimulated radiation. The laser light propagates and amplifies in the optical fiber and is finally output through the end of the optical fiber. A dvantages 1. High beam quality: The beam produced by the fiber laser has high beam quality and low beam divergence.   2. High efficiency: The optical-to-electrical conversion efficiency of the fiber laser is very high, usually between 30-50%.   3. Good heat dissipation performa...

MOPA pulsed fiber laser is used to clean copper hair-pins in the new energy field

Image
The electric motor is one of the core parts of new energy vehicles and is constantly developing towards high power density and high motor efficiency. The application of flat enameled wire can significantly increase the effective copper area and reduce copper consumption. The copper wires in the slot are arranged more regularly and the slot full rate is higher, thus improving the efficiency and power density of the drive motor. The trend of automobile intelligence and electrification is obvious. Due to the increase in demand for hair-pin motors , the demand for flat enameled wires has also been further expanded. The copper hair-pin inside the motor must ensure insulation and achieve electrical isolation. It is usually covered with a layer of paint or an organic insulation layer. Before hair-pin welding, the insulation layer in the welding area needs to be effectively removed. Mechanical stripping can damage the wires, and CO2 lasers often cannot completely remove the insulation. Based ...

Application of UV laser on ceramic materials

Image
In modern industry, ceramic materials are widely used in various fields due to their excellent physical and chemical properties. From sophisticated electronic components to demanding industrial equipment, ceramics have become one of the important materials to promote scientific and technological progress with their irreplaceable advantages. However, how to make lasting and clear marks on these materials has always been a difficult problem in industrial processing. With the development of laser technology, laser ceramic blackening technology came into being, providing an efficient and environmentally friendly solution to this problem. Traditional ceramic blackening technology mainly relies on mechanical engraving or chemical etching. These methods not only have problems such as low precision, low efficiency, and easy damage to materials but also have many consumables and great environmental pollution, which are not in line with the concept of modern green manufacturing.   Laser pro...
