Welding processes in the automotive industry pose a special challenge for production planners. The process must be performed within seconds and without any negative impact on the material – anything but a trivial requirement when one considers the high process temperatures. Pre-heating before welding, therefore, takes a key role. The component is heated precisely to the required process temperature of around 160 to 180 degrees Celsius. This prevents unwanted heating of the material structure in the heat-affected zone, the area directly surrounding the weld. Pre-heating effectively prevents the formation of cracks in the component after welding.

Induction heating is ideally suited for setting up automated production processes. The technology is easy to integrate into the overall process flow and enables the machining of very large part quantities quickly, precisely and safely. Hardening, joining, brazing and pre-heating are examples of applications that benefit from this flexible technology.
