Xiaolan Huangpu light box Guzhen precision metal parts laser welding machine is the letter of non-standard custom equipment

1, the laser works 1.1, YAG laser works by laser power is first pulsed xenon lamp lit by a laser pulse discharge xenon lamp power supply, a certain frequency, a certain width of waves, the waves radiated through the condenser chamber to Nd 3+ : YAG laser on the crystal, excited Nd 3+: YAG laser crystal light, then go through the laser cavity resonance, emit a wavelength of 1064nm pulsed laser, the pulsed laser through the beam expander, after reflection, (or by the optical fiber transmission) Focus hit on the object to be welded; under the control of the PLC or industrial PC and mobile CNC table, thus completing the welding. Frequency, pulse width, wave, table speed, direction of movement of the welding laser pulses required are available microcontroller, PLC or industrial PC to control, through the laser frequency, the pulse width of the control pulses of different laser settings can be adjusted energy. 1.2, the working principle of the fiber laser pump light through the fiber when the rare-earth ions, will be absorbed by the rare earth ion. Then the rare earth atoms absorbed photon energy electrons will be excited to a higher energy level lasing, enabling ion inversion, number of ions will be reversed in the form of the transfer of radiation from high energy level to the ground state, and the release of energy, completed by stimulated emission of radiation. Generated by the laser fiber laser optical output, and with the support of the table with the completion of the appropriate welding. Fiber laser pulse into a continuous fiber lasers and fiber lasers. Among them, the pulsed fiber laser can be used to adjust the laser pulse energy through a single point of the peak power of the laser frequency, pulse width setting; CW fiber lasers by setting the average laser power to regulate the output laser power. Laser welding machine is a kind of the focused laser beam as an energy source, focused onto the workpiece to be welded to the metal, since the laser having an optical refraction properties, focus, etc., so that the laser welding is very suitable for micro parts and poor accessibility of the site welding. Laser welding also has a low heat input, low distortion, from electromagnetic influence, simple operation, stable, good weld results. High welding efficiency, simple operation, can be automated welding, suitable for welding various materials planar linear, circular and arbitrary trajectories. After the appearance of fine welding, weld not black, the product is not deformed, combining the advantages of laser welding machine and high range of applications:!?
