  • Model: YAG300
  • Laser type: YAG
  • Laser wavelength: 1064nm
  • Product description: 300W YAG laser welding machine is mainly used for welding thin-walled materials and precision parts. It can realize spot welding, butt welding, stitch welding and sealing welding with high depth ratio

YAG Laser welding machine principle

The laser welding adopts high-energy pulsed laser to achieve welding. The laser power source first activates the pulsed xenon lamp, and impulsively discharges the xenon lamp to form the light wave with certain frequency and pulse width. The light wave is radiated onto the Nd3+:YAG laser crystal through the condensing cavity to stimulate the Nd3+:YAG laser crystal to emit light. After the resonance of the laser resonator, a pulsed laser with a wavelength of 1064 nm is emitted, and after the pulsed laser beam's expansion, reflection, focusing(or transmission through the optical fiber) then hit on the object to be welded. The welding is completed under the control of a PLC or an industrial PC.

1. It is mainly for thin-walled materials, precision parts welding.
2. Spot welding, butt welding, lamination welding, sealing welding are all ok.
3. It has high depth ratio, small weld width, small heat affected zone, little deformation and fast welding speed.
4. The weld seam is smooth and beautiful, no need further processing or only simple processing is needed after welding.
5. High weld quality, free of porosity, can reduce and optimize the impurities of the base metal, structure can be refined after welding, the weld strength and toughness are at least the same as a base metal's.
6. Precisely controll, small focus spot, high precision positioning, easy for automation.
