Wentz qualifications and certifications

Qualifications & Certifications

THE HIGHEST QUALITY STANDARDS AND QUALIFIED EMPLOYEES ARE MUTUALLY DEPENDENT. IN ORDER TO IMPLEMENT YOUR PROJECT IN THE BEST POSSIBLE WAY, WE HAVE A WIDE RANGE OF EXPERTISE AT OUR DISPOSAL.

Competence in steel

Standards that go beyond those customary in the industry

This includes holding a welding certificate in accordance with DIN EN 1090-2 up to execution class 3 (EXC3). This means that we can and are permitted to manufacture steel structures which are subjected to predominantly static and dynamic (i.e. not predominantly static) loads. Dynamically stressed components include crane runways and bridges for pedestrians and cyclists.

In order to carry out this work in accordance with the highest quality requirements, we utilise modern welding processes such as impulse welding & CMT welding. Our welders undergo regular training and the welding supervisors also receive regular instruction. We deploy the following welding processes:

  • 135 MAG welding
  • 141 TIG welding
  • 783 drawn arc stud welding

On construction sites and in the case of special requirements, we also use welding process 111, manual arc welding. We have acquired considerable expertise in the materials we use, from standard structural steels S235 to S355, through corrosion-resistant stainless steels, and on to special heat-resistant steels and stainless steels.
