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.
