YAG laser welding machine works

The laser power first ignites the pulsed xenon lamp and discharges the xenon lamp through the laser power to form a certain frequency and a certain pulse width. The light is radiated to the Nd 3+: YAG laser crystal through the condenser cavity to excite Nd 3+: YAG After the laser crystal emits light and resonates through the laser resonator, the pulse laser is emitted at a wavelength of 1064 nm. The pulse laser is focused on the object to be welded after being expanded, reflected, (or transmitted by fiber). In the PLC or industrial PC Under control, move the CNC table, thus completing the welding. The pulse frequency, pulse width, waveform, table speed and movement direction of the pulse laser required for welding can be controlled by the single chip computer, PLC or industrial PC. By adjusting the frequency and pulse width of the laser, the control pulse laser energy of.

The working principle of fiber laser welding machine

When the pump light through the fiber in the rare earth ions, it will be absorbed by rare earth ions. At this time the absorption of photon energy of rare earth atoms will be excited to a higher lasing level, in order to achieve the number of ions inversion, the number of ions after the reversal of radiation from the high-level transition to the ground state, and the release of energy, Complete stimulated radiation. Fiber laser welding machine generated by the laser output through the fiber, and with the matching table to complete the corresponding welding. Fiber laser welding machine is divided into pulsed fiber laser welding machine and continuous fiber laser welding machine. Among them, the pulse fiber laser welding machine can be laser peak power, frequency, pulse width settings to adjust the laser pulse single point of energy; continuous fiber laser welding machine by setting the average laser power to adjust the output laser power.
