Precision due to welding in ideal position
Thanks to horizontal welding with highly modern
welding processes, a more homogeneous structure, a
deeper root penetration and notch-free welding
surfaces are achieved.

Use of welding robots
Semi-automatic and fully automatic welding robots
are used for consistently high quality on highly-
stressed welding seams.

Low-stess materials
Modern plasma and laser cutting systems ensure
smooth metal processing and cutting. This means
that our boilers have higher stress reserves during
operation.

In-house manufacture of flame tubes
All smooth and corrugated flame tubes are manufac-
tured in-house and are subject to the most stringent
quality requirements. Up to 100 % of the welding
seams are X-ray inspected.

Highest level of quality monitoring
Quality has the highest priority with us. Factory
inspectors, who are certified by TÜV, together with
TÜV's own staff, constantly monitor and document
our quality during the entire manufacturing process
right up to the acceptance.

Precision and analysis
An in-house laboratory inspects welding seams and
analyses materials, so that maximum transparency is
maintained. Over 25,000 X-rays of welding seams are
evaluated every year in our three X-ray chambers.
