  1. A high ratio of welding depth to spot diameter results in slender laser welding seam, small affected area, little thermal distortion, and fast welding.
  2. The welding seam is smooth, therefore there is little or no need to polish the seam after welding.
  3. The welding seam is in high quality with no gas bubbles left behind. The process can even improve the impurity of the mother material.
  4. The welding spot is very small and can be positioned accurately. It can match robot to do any position welding job.
  5. Two of the same material or different materials can be welded.


System Character

  1. 360°rotating of the welding head, facula adjusting by hand-moving.
  2. MOTIC microscope + liquid-crystal light-valve protector.
  3. Real-time currency feedback system to ensure the stability of the laser power.
  4. Industrial touch-screen interface.
  5. Can repair crack, burst corner, die edge, and wearing seal edges.

The laser welder can weld the same material like titanium, nickel, tin, copper, aluminum, chromium, niobium, gold, silver, steel and their alloys. And it can weld two different materials, like copper-nickel, nickel-titanium, titanium-molybdenum, brass-copper, low carbon steel-copper.

It also can be applied widely to mobile phone batteries, sensors, clocks, watches, jewelry, electronic components, eye glasses, crafts precision instruments and medical apparatus etc.
