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

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...
