Application Scenarios
New Energy Battery Welding
Laser welding is a widely used new welding method. It can realize spot welding, splice welding, stack welding, seal welding, etc. for workpieces of different thicknesses and materials. The welding seam is narrow, the heat affected zone is small, the deformation is small, the welding speed is fast, the welding seam is smooth and beautiful, and it is easy to realize automated production, which can greatly save manpower and time. The quality stability of new energy battery shell welding will affect the consistency and safety of the battery assembly system. The sealing and welding of the battery case and cover is very demanding, and its welding quality directly affects the quality of the battery. The spatter generated during the laser welding process may cause an internal short circuit in the battery core, but the new beam-adjustable laser can effectively suppress the generation of spatter and greatly improve the welding quality.
High Power Laser Cutting
Laser cutting is primarily a thermal process in which a focused laser beam melts material in a localized area. Coaxial gas jets are used to eject molten material and create cuts, allowing continuous cutting to be achieved by moving the laser beam or workpiece under CNC control. Improvements in precision, edge flatness and control of heat input mean that laser processing is increasingly replacing other profile cutting technologies such as plasma and oxy-combustion. Advantages of laser cutting include: Narrow cut width, smooth edges and good appearance; The heat affected zone near the cutting edge is small; The heat is small and the workpiece deformation is small; Precise control of average power eliminates excessive combustion during acceleration and deceleration; There is no mechanical deformation of the workpiece; No cutting tool wear, maintenance or replacement issues. YOFC has developed several single-mode and multi-mode high-power fiber lasers (1.0-30kW) for cutting ferrous and non-ferrous metals. Laser cutting is performed using different auxiliary gases and processing parameters, i.e. oxygen, air, nitrogen and argon to cut different materials and thicknesses. Cutting quality was analyzed in terms of cutting speed, cut edge appearance, burr formation and kerf width. The photos below show laser cut edges in a variety of materials and assist gases, including thin aluminum sheets cut at high speeds (>53 m/min).
Metal 3D Printing
Laser 3D printing is a technology that creates new workpieces by melting elemental or alloy powder. After the laser beam leaves, the alloy liquid quickly solidifies and shapes. The beam quality of the laser can determine the quality of printing, such as fineness, etc. The customized electronic control program allows dual lasers to work on the same object at the same time, shortening the printing time by twice without affecting the printed product at all. Print Time.
Cladding Quenching
Laser cladding technology is a new technology with high economic benefits. Laser and alloy powder act simultaneously on the metal surface to form a metallurgical bonding layer, thereby achieving the effect of repairing the workpiece surface and strengthening and extending the service life. High-performance alloy surfaces can be prepared on cheap metal substrates without affecting the properties of the substrate, reducing costs and saving valuable and rare metal materials. Compared with surfacing, spraying, electroplating and vapor deposition, laser cladding has the characteristics of small dilution, dense structure, good combination of coating and substrate, many suitable cladding materials, large changes in particle size and content, and good controllability. , can realize three-dimensional automatic processing with high processing quality. Therefore, the application prospects of laser cladding technology are very broad.
3C precision welding
In the future, 3C products will be upgraded in the direction of high integration and high precision. The internal components of their products will become smaller and smaller, and the electronic integration will become higher and higher. Therefore, the appearance, deformation, and pulling force of internal structural parts place higher and higher requirements on welding technology. Laser products, due to their high energy, high precision, and high directionality characteristics, make the products lighter, slimmer, and more stable, and are widely used in applications such as welding of internal structural parts of 3C products. YOFCs QCW series lasers have the advantages of good beam quality, long pulse width, and flexible installation. By generating a pulsed laser with a wavelength of 1080nm and expanding, reflecting, focusing and radiating it on the surface of the workpiece, the surface heat diffuses to the interior through thermal conduction, and parameters such as the width, energy, peak power and repetition frequency of the laser pulse are precisely controlled digitally. , melt the workpiece and form a specific molten pool, thereby realizing laser welding of the workpiece and completing precision welding that cannot be achieved by traditional processes. And for parts that are difficult to access for welding, flexible transmission and non-contact welding are implemented, which has greater flexibility. Compared with traditional YAG laser, it has the advantages of higher brightness, higher efficiency, and smaller size, making it the best choice for green energy solutions.
Laser Cleaning
Laser cleaning is a cleaning method that is different from the traditional cleaning industry. It relies on the characteristics of the light pulses generated by the laser and is based on the photophysical reaction caused by the interaction between the high-intensity beam, short-pulse laser and the pollution layer. The traditional cleaning industry mostly uses chemicals and mechanical methods for cleaning. Today, as environmental protection regulations become more and more stringent and people awareness of environmental protection and safety is increasing, the types of chemicals that can be used in industrial production cleaning are becoming fewer and fewer. Laser cleaning has the characteristics of non-abrasive, non-contact, and no thermal effects. It is suitable for objects of various materials. It solves the problems of traditional cleaning methods that easily cause pollution and damages the environment. It is considered to be a reliable and efficient industrial cleaning solution.
Laser Long Distance Obstacle Clearance
Laser obstacle removal equipment is a device that uses laser beams to remotely clear foreign objects on overhead lines. It can remotely remove foreign objects and obstacles on wires in a non-contact manner on the ground. It has the characteristics of high efficiency and high safety, and overcomes the limitations of traditional processing methods. shortcoming. In some areas with complex lines, such as large substations, laser obstacle removal can easily remove obstacles that workers cannot climb and handle. Laser obstacle removal can easily remove obstacles. The principle is to aim at the target through the sighting system, and irradiate a laser beam of a certain energy on the target foreign object to vaporize or fuse it to achieve the purpose of clearing the foreign object (Note: the straight-line distance of the laser is 50-200 meters)
