Soutube

Laser welding system for round, oval, and polygonal tubes as well as cylindrical, conical, or multi-diameter tubes

Soutube can weld the tubes mentioned in a virtually continuous process. It can also produce tubes of different wall thicknesses, such as tailored tubular blanks or tailored rolled tubes (TTB or TRT). Tubes produced on the Soutube are mainly for security-related applications in vehicles and require an extremely stable and reliable laser welding process.

The technology offers perfect tubes for the hydro-forming process and for lightweight applications in general in the automotive field for body-in-white or suspensions. The Soutube is used in automotive and vehicle manufacturing. In combination with a press, it can produce far more than one million tubes per year. The built-in seam tracking and quality inspection system guarantees a stable process for highest demands.

If required, the system can weld with Soutec’s unique filler wire system, Soufil. In the process, the filling volume is controlled via wire speed.
