Jewelry Laser Spot Welder - W50G

View All Han's Laser

W150G 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.

The whole machine is compact and equipped with a glove box and microscope coaxial focus positioning aiming, liquid crystal light valve and full anti-eye protection device to achieve precise positioning. With laser power real-time feedback control system, based on the preset laser waveform, the system could detect laser power and feedback control the laser source in real time, adjust the output current of the power supply so that laser energy is always stable. The laser power real-time feedback control system eliminates laser energy instability caused by grid fluctuations, water temperature changes, xenon lamp aging, etc., and improves the consistency of welding products.

Jewelry Laser Spot Welder - W50G Details:

  • High aspect ratio, thin weld width, narrow heat affected zone, zero deformation, and fast welding speed
  • The weld is smooth and clean, 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, the weld strength is at least equal to or even exceed the base metal strength
  •  Tiny laser spot can be precisely positioned and easily automated
  • Fit for some dissimilar metal welding
  • Spot welding, butt welding, overlap sealing welding
  • Various metals such as gold, silver, platinum, stainless steel, titanium, and their alloys

This laser spot welder is mainly used for repairing holes of gold and silver jewelry, seams and claw parts. It can be applied to a variety of metals and alloys such as,
  • Gold
  • Silver
  • Platinum
  • Stainless steel
  • Titanium
Also can be used to repair dentures and other small parts welding such as,
  • Battery nickel tape
  • Integrated circuit leads,
  • Clock spring, picture tube, etc.
The heat affected zone of the welding process is narrow, and the spot size is adjustable; Smooth and clean result does not require excessive post-weld treatment;

Laser can be accurately positioned to avoid damage to jewelry.
