Designed for fine microwelding with focused spot sizes down to 10 µm, the LF fiber laser welding system manufactured by Miyachi Unitek Corp. offers precise control of pulse width and peak power. The laser is available in single- and multimode options. Applications include welding of flexure arms on hard disk drives, medical spring attachment and medical component assembly. The LF laser features an internal air-to-water cooling mechanism, ensuring good power and pulse-to-pulse stability, irrespective of the ambient air temperature. It can be operated in either pulsed or continuous-wave mode and offers the features necessary for control of the weld. The control interface can be integrated into the laser or provided separately for workstation use. The LF laser can be integrated with any motion platform.
