Solid State tube welding systems are designed as economical modular units based on transistor technology ranging from 50 to 2000 Kw.

The ideal frequency selected from a range of 50-600 KHz guarantees optimal conditions for HF welding of steel, aluminum, brass or copper. The control, regulation and monitoring functions can either be implemented locally or linked to a down stream seam annealing process.

Using the adjustable support, the inductor positioning can be set in up to three axes in any of the three following ways - manually, using in electric motor or by numerical control.

Induction and conduction heating of tubes are keys to increase productivity and quality assurance.

HF seam welding for tubes and shaped sections, MF seam annealing, induction tube heating for a range of subsequent processes such as sizing, tube bending, tempering, coating etc are key aspects of this technology. A decisive factor in the manufacture of tubes is the precise matching of all the machining processes to each other.
