     Nd: YAG Laser Spot Welder PB Series

PB series utilizes a laser source that excites Nd: YAG crystal using a pulsed Xenon lamp that resonates to create a laser with a wavelength of 1064 nm.

With good beam quality, fine laser spot, strong penetration and fiber transmission, an excellent non-contact long-distance, precision spot welder is produced. Highly recommended for integration with automated production lines.

Equipped with a real-time laser power feedback control system, the preset laser power can be controlled using
 feedback to adjust laser power in real time. The power supply output is adjusted so laser energy is always stable.

The real-time feedback control system eliminates laser energy instability caused by grid fluctuations, water temperature changes, xenon lamp aging and significantly improves consistency of welding prod
ucts.


Features
 

         ● High aspect ratio, thin line weld width, narrow heat affected zone, zero deformation, and fast welding speed

● Smooth and clean weld with or without simple process after welding
● High weld strength, no porosity, eliminates the impurities of the base metal
● The microstructure can be refined after welding, Weld strength is at least equal to or exceeds base metal strength
● Tiny laser spot can be precisely positioned and easily automated
● Suitable dissimilar metal welding
● Excellent for spot welding, butt welding, overlap sealing welding.
