200w 300w 400w 500w Universal And Continuous Laser Welding Machine For Metal
200w 300w 400w 500w Universal and continuous laser welding machine for metalLaser welding machinePrinciple of laser welding machineThe principle is to use high-energy beam focusing on the surface of laser welding parts to locally heat and melt the material to form a weld. The main features of the process is non-contact welding. No stress and deformation will be caused by external force. Since the heating time is only a few milliseconds, the thermal effect of the material confined within the laser beam spot, the welding heat affected zone is very small. Coaxial welding device usually multi-point light welding technology, minimizing the welding deformation on the coaxial device performance. Meantime, welding process time is short, with very high production efficiency the large-scale mass production has become possible.3.Equipment system components3.1 laser systemsWelding machine is adopting the solid-state lasers with working substance of Solid material, pulsed xenon lamp as the optical pump source. Solid-state laser generator consists of working material, the pump source, condenser chamber, an optical resonator, filter components and laser cooling power.3.2 Laser power supply systemPulse laser power supply is dedicated to the special pulse xenon lamp power supply power supply system,which is generally made of the charging circuit, energy storage unit and discharge circuit, trigger/precombustion circuit, logic control circuit and electric circuit of operation.3.3.Cooling system specially made for laser machinePatented design, cooled by double circulation, warmth control system can be controlled precisely. This cooling system is totally made of coil pipe structure of titanium alloy material. Evaporator,water tank and pump body and so one are all made of stainless steel and non-metal materials with good quality in order to keep water quality. Imported low noise and jet flow self priming centrifugal pump can make purified water cool laser supply via internal recycle. refrigeration compressor can make recycling water cooler via the second recycling.4.Technical Parameters●Laser supply-pulsed solid-state laser ●Laser operation material:Nd3+:YAG●Laser wavelength:1.064m●Maximum laser pulse energy:50J（laser output separately from laser heads)●Power of maximum laser peak:5KW●Width of laser pulse:5~15ms continually adjustable●Repetition frequency of pulse:1~100Hz continually adjustable●Waveform Quantity: can be freely set, conserved number is no less than 30 sets●Control system: feedback of laser power given at real time in closed loop.
