Current news from surface technology

Successful extension of our Nadcap-accreditation

One year after our first Nadcap audit, the reaccreditation audit for the extension of our welding certification was due in mid-April.

We were able to pass this audit without any nonconformances and thus extend our Nadcap certificate by one year.

In addition, we are currently preparing to have our NDT processes (non-destructive testing) Nadcap-accredited by the end of the year.
