Request Info

AMADA MIYACHI’s LF range of fiber lasers are efficient, low maintenance manufacturing tools that offer precise control and a range of beam qualities which can be tuned for each specific welding application. They are particularly well suited for small component welding, like photonic device welding and electrical connections. A large touchscreen pendant enables clear visibility of process schedule parameters, and an intuitive user interface enables quick and easy programming.

Fiber laser sources up to 1000 W are available in both single- and multi-mode configurations and may be operated in either pulsed or CW mode ensuring application success across a broad range of production requirements.

Continuous wave (CW) Lasers

With a CW laser, the laser output remains continuously on until being turned off. The laser output can also be modulated – this means the laser is turned on and off rapidly providing a pulsed delivery of the energy. The CW laser’s peak power is the same as its maximum average power. With excellent beam quality, focused spot sizes are generally range between 20-100 microns. CW fiber lasers are usually a good choice for general seam welding up to 0.06-inch depth for a 500W laser, high-speed seam welding of same and dissimilar materials, and spot welding thin metals.

Quasi-continuous wave (QCW) Lasers

The QCW fiber laser’s peak power and pulse width characteristics are similar to those of the Nd:YAG laser. The QCW lasers offer single-mode to multi-mode options with spot sizes from 0.001-inch to 0.04-inch (25 micron to 1 mm). These lasers also shine in small spot size applications and penetration applications, although they really can handle many micro welding applications. All lasers are proudly built in the USA.
