Welding Equipment

The oldest traces of welding techniques can be found in the Bronze age, more than 2.000 years ago, in boxed made out of gold. In the Iron Age, humankind learned to weld iron together and in the Middle Ages, blacksmiths still used a hammer. Modern welding was invented in the 19^th century and has seen several innovations and new technologies. The latest is the introduction of laser into welding processes.

Laser beams can melt and even vaporize metals highly efficiently and very precisely. Joining thin sheets is therefore the domain of the laser. Whether soldering or welding, the seams are always extremely narrow, accurate and durable. The high energy applied at specific points allows impressive welding speeds. However, this performance requires high-precision control and positioning of the laser.

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. The automatic wire feeder driven by a controlled micromotor is another important application for our highly reliable drive systems.
