Automatic laser welding machine is generated from application laser wavelength of 1064nm pulse laser through expanded beam reflector, focusing the radiant workpiece surface, the surface of the heat through the heat transfer guide internal diffusion through digitization precise control of laser pulse of width, energy, peak power and repeat the frequency and other parameters, so that the workpiece melting, formation of specific molten bath in order to achieve the laser welding on a workpiece. KDY-LWA200 solid laser welding machine is a high-performance solid pulse laser processing equipment, with a high photoelectric conversion efficiency, high stability, small size, configuration, and high. Mainly used for welding of metallic materials processing, solid solder joint appearance, a small heat-affected zone, high efficiency, low welding cost. Has a wide range of applications in microelectronics, aerospace equipment, optical communication equipment, electric vacuum devices, instrumentation, mechanical and electrical products, automotive manufacturing industry. "The Cape Cod excellent laser" LWA200 automatic laser welding machine has the following characteristics: 1) LWA200 imported ceramic reflective condenser cavity structure, high conversion efficiency, no-clean. The ceramic reflector reflective surface is glaze, reduce the cost of equipment downtime, repair costs and condenser chamber; the ceramic reflector is a diffuse reflection effect, reflective condenser uniform makes laser output beam is more uniform, and low lasing threshold ( light), easy commissioning and maintenance of the laser, and can extend the life of the krypton lamp 3-4 times. 2) using pulsed laser power, laser welding IGBT constant current switching power supply, adjustable pulse waveform controllable function, able to adapt to different material objects. The main control unit using a single-chip digital control. 3) Laser welding speed, high efficiency, welding depth, small deformation, weld beautiful, beautiful. Welding refractory materials, micro parts precision welding welding difficult-to-reach parts of the purposes of the non-contact remote welding, with a great deal of flexibility, scan driver fully reflects the flexible and degree of automation of the processing means 4 ) integrated water cooling structure. Jet self-priming centrifugal pump, stainless steel structure, with platinum resistance temperature sensor, dual temperature control, digital display. Refrigeration unit refrigeration, liquid level control switch.
