Welding and painting


KMW Engineering has highly qualified supervisory, working, and inspection personnel, responsible for welding works during production and assembling processes. We offer production of welded ventilation products and construction of welded technical systems. See also Contract Manufacturing.

We specialise in welding of carbon and stainless steels. The implemented WPQR welding technologies were approved by TÜV. Furthermore, we specialise in welding of thin steels from 2,00 mm. Our welders hold licences issued by IS and supervision licenses from TÜV.

In our new facility we weld with welding robots and manually.

KMW implemented and maintained the welding quality management system in accordance with EN-ISO-3834-2:

  • Welding supervision                                                                                                                                               

The welding quality system is supervised by the certified welding engineering personnel, IWE with recognised European and international certificates issued by IIW and EWF.

  • Welders

The welding works are performed by certified welders with qualifications conforming to EN ISO 9606-1 standard.

  • Inspection

The welding works are inspected by non-destructive tests (NDT) inspectors qualified at the second level in accordance with the EN 473 and EN ISO 9712.

Additionally, we have highly qualified welders working in the area of arc braze welding of austenitic and zinc or Aluzinc-coated metal sheets with an argon gas shield with the 972 method. This method is, for example, used for production of panel structures and ventilation ducts of the air tightness class D.

KMW Engineering holds a certificate for welding works, as we meet the requirements of DIN EN ISO 3834-2. The certificate was issued by TÜV Nord.


We use more than 20 different types of painting methods according to the highest standards requested by nuclear or naval industry.

In our new facility we paint with painting robots and manually.

To keep the highest standard in our production we are able to weld and paint our products in a state of the art new facility.

Power & Free system for transportation of details makes painting very competitive and efficient.

We can easily use those capacities also for your product. Just see Contract Manufacturing.
