Accurl Handheld Laser Welding Machine

I. Core Working Principle (Interaction between Laser and Material) 1. Energy Absorption and conversion The laser generates an extremely fine, highly bright and monochromatic laser beam. This laser beam is transmitted through optical fibers to the handheld welding torch. After collimation and focusing, it irradiates the surface of the metal workpiece. Metallic materials can absorb the energy of lasers (especially in the infrared band, such as 1064nm, for which metals have a relatively high absorption rate), and instantly convert light energy into thermal energy. - Melting and molten pool formation: In the tiny area irradiated by the laser (the focal diameter is usually only a few tenths of a millimeter), the energy is highly concentrated, the temperature rises sharply, and the metal melts or even vaporizes rapidly. As the welding torch moves, the laser beam moves synchronously, and the molten metal area also moves and cools and solidifies at the rear. This continuously flowing area of liquid metal is called the "molten pool". - Weld formation: The metal at the front end of the molten pool keeps melting, while the metal at the tail end keeps cooling and solidifying, thus forming a continuous and uniform weld seam. Due to the highly concentrated laser energy, the heating and cooling speeds are extremely fast, thus the heat-affected zone is very small and the workpiece deformation is also minimal. Ii. System Composition and Collaborative Work A complete handheld laser welding machine is not merely a gun; it is a system mainly consisting of: 1. Laser: The "heart" of the system, usually a fiber laser is adopted. Because of its high efficiency, good beam quality, relatively small size and maintenance-free nature, it is very suitable for handheld applications. The power range is usually between 1000W and 2000W, and it is suitable for welding materials of various thicknesses. 2. Cooling system: When the laser is in operation, it generates a large amount of heat and requires a matching chiller for cooling to ensure the stable and long-term operation of the laser. 3. Control system: The "brain" of the machine, integrated within the main unit. It is used to set and adjust parameters such as laser power, frequency, and duty cycle, and monitor the operational status of the entire system. 4. Handheld welding gun: This is a key component for achieving "handheld" operation. It contains: - Collimating mirror: Converts the divergent laser emitted from the optical fiber into parallel light. - Focusing mirror: Focuses the parallel laser beam onto the surface of the workpiece to form a high-energy-density spot. - Protect the lenses: Prevent spatter generated during welding from contaminating and damaging the internal optical lenses. - Indicator light: Usually a red LED or low-power laser, it is used to indicate the position of the current laser focus, facilitating the operator's aiming. - Wire feeding system (optional) : Many handheld welding torches are integrated with or equipped with external wire feeding machines, which automatically and precisely feed the welding wire into the molten pool when it is necessary to add welding wire during welding. - Protective switch: Light will only come out when the switch is pressed to ensure safety. 5. Supporting workbench: including platforms for placing workpieces, fixtures, etc.   f you have more ideas, please contact us!
