The ALmicro is a simple and inexpensive solution to perform contact weldings to very small compo-nents, such as thermocouple wires, with high process reliability..
The observation objective is equipped with a 55x magnification. The diameter of the laser beam can be reduced very fine to 0.05 mm, thus ensuring that the materials to be welded are liquefied and connected only in a very small and defined area. Result: The thermal stress is minimized and the parts to be processed are not warped. The high laser pulse frequency of up to 50 Hz provides a quasi-CW-weld.
