The temperature rises rapidly and reaches the boiling point of the material in a very short period of time. Laser cutters are credited with keeping the U.S. garment industry competitive in the world market. Laser engraving is the most popular advanced marking method globally, which is very suitable for modern production (high efficiency and fast pace). The comparison of several marking techniques. At the same time, the production of a single and small batch of precision castings can be used without the mold, thus saving a lot of tooling costs and greatly shortening the production cycle. Lasers have been used aboard spacecraft such as in the Cassini-Huygens mission. Today, laser technology is used in all walks of life. The first three cutting methods are the main application of laser cutting. Applications of laser are becoming very important topic in the current research. At the same time, the workpiece is cut off by blowing the molten material with the high-speed airflow with the same axis of the beam. By far the largest single application of lasers is in optical storage devices such as compact disc and DVD players, in which a semiconductor laser less than a millimeter wide scans the surface of the disc. . Easy to achieve synchronous flight printing with the production line. Application of laser: Laser are used in many various field. (9) When welding thin material or thin diameter wire, it will not be as easy as arc welding. Small cutting seam (high utilization rate), There is no mechanical stress in the incision, There is no need to process or simply process after welding. (5) When using high energy laser beam welding, plasma controller is used to removing the ionized gas around the molten pool to ensure the reconstruction of the welding channel. Supermarket scanners typically use helium-neon lasers to scan the universal barcodes to identify products. Laser welding is the main welding process in the manufacturing of high-speed railway and automobile. (6) Energy conversion efficiency is too low, usually less than 10%. There are thousands of items that have been laser marked or laser engraved. But lasers offer some new possibilities for selective heat treatments of metal parts. (1) During laser welding, the amount of heat input can be reduced to the minimum requirement, and the range of metallographic variation in the thermal effect area is small, and the deformation caused by heat conduction is also minimal. for cutting, drilling, welding, cladding, soldering (brazing), hardening, ablating, surface treatment, marking, engraving, micromachining, pulsed … The machine requires isolation from the earthquake focus and ensure that the laser is in dry and constant temperature. Fiber optic cables are a major mode of communication partly because multiple signals can be sent with high quality and low loss by light propagating along the fibers. The optical path structure of CO2 laser is more complex and optical lens loss is larger. In this video I'm talking about some of the real-world applications for lasers. This technology has already proven to be a user-friendly as per the need . Especially in the stage of product development, considering various factors comprehensively and use the rapid prototyping technology to enable the development to be successful at once. Traditional cutting techniques include gas cutting, machining cutting, blanking cutting, plasma cutting, etc. The programmed cutter can cut dozens to hundreds of thicknesses of cloth, and can cut out every piece of the garment in a single run. The cutting cost is large and the subsequent processing cost is higher. (2) When the welding parts need clamps, must ensure that the final position of the weld is aligned with the welding spot where will be impacted by the laser beam. Heat treatments for hardening or annealing have been long practiced in metallurgy. The highly collimated beamof a lasercan be further focused to a microscopic dot of extremely high energy density. The laser oscillator output can be formed when the positive feedback loop is added in due course. Laser based LIght Detection And Ranging (LIDAR) technology has application in geology, seismology, remote sensing and atmospheric physics. . Application of laser in space communication: Lasers used in free space laser communication systems, it’s one of the most important application of laser in communication either semi-conductor laser diodes, solid state lasers and fibers amplifiers lasers. Laser in MRI ( Magnetic Resonance Imaging ) Laser In Eye Treatment 14. Your email address will not be published. The development and development of new products save a lot of precious time and reduces the production cost. In the main large manufacturing, such as automobiles, electronics, machinery, aviation, steel and other industries, some countries have basically completed the changes from traditional processing technology to laser processing and enter into the era of “light”. Although the cutting speed is fast and the cutting thickness is large, the cutting size precision is obviously not good.
