ML-8150A provides 5W of maximum power, which is upgraded more than twice compared with the conventional machine. It enables faster and deeper welding of even copper and gold, which have high reflectance to YAG fundamental laser and are hard to be welded.
Further, its beam becomes so thinner than the conventional one that deeper, thinner, and more beautiful welding can be achieved.


  • Solid welding of cupper and gold by SHG laser.
  • 5W power achieving deeper penetration and faster operation.
    (Power density is nine times as high as the conventional model.)
  • Ø0.2mm fiber enabling high quality precision welding.
  • High speed pulse control to shorten the takt time.
    (Pulse frequency is three times as high as the conventional model.)
  • Two simultaneous energy share enabling two simultaneous processings and processing from two different angles.
  • AMADA MIYACHI's original power feedback feature.
  • Hybrid laser system combined with fundamental and SHG laser achieving deeper penetration.
  • Easy-to-use jog dial.

Why can laser weld copper and gold?

SHG laser is green-colored visible light with wavelength of 532nm, which is a half of fundamental laser (1064nm).


Absorption of laser into copper and gold is 4.5 to 20 times higher than fundamental laser so that it is possible for laser to weld copper and gold.

Expand the Environmentally-friendly Method of Welding

Manufacturing by lead-free soldering and solder-less joining methods is recently required considering protection of the environment. Especially for electronic device manufacturing, their reliabilities have been a significant issue lately.

The Solution is... Laser Welding!

  • Heat-affected area can be reduced so that parts with weak heat resistance can be welded.
  • No flux is necessary.
  • No solder creeping.
  • Size and weight of parts can be minimized as solder is reduced.

Hybrid Laser Welding System

By combining SHG laser (ML-8150A) and fundamental laser (ML-2000 series) at the focus unit as illustrated at right, the welding depth and welding spot diameter are greatly improved comparing to that of a single laser.



Welding of electronic devices, electric devices, IC leads, gold-plated patterns and more.
