There are various processes available for automated soldering or welding. Whether soldering, induction brazing or laser welding – the weld filler metal is often delivered by wire. However, this is exactly where the difficulty lies. The system must always deliver a reproducible length of filler metal to the correct destination, but without jolting or bending the wire in the process. A new automatic wire feeder driven by a controlled micromotor is now providing a reliable solution to this problem.
Soldering and welding are ancient techniques for joining metals that are also ideally suited to modern, automated fabrication processes. To achieve reproducible results, it is important to adhere to all parameters, particularly temperature and quantity of filler metal. Dusslingen-based company EUTECT GmbH has taken up this challenge and has developed an adjustable, customizable soldering and welding wire feeder. An automatic status message about the amount of weld filler used allows for optimum dosing and provides a record of operating data. EUTECT’s soldering experts have been working with the Schönaich-based microdrive specialist FAULHABER to realize a wire feed system that is both flexible and accurate. The result is a compact, adaptive wire feed unit that is nevertheless highly responsive to individual requirements.
