History
|
Welding Technology and NDT Research/Application
Centre of Middle East Technical University (METU) is founded in
1988 within the frame of a bilateral project between Turkey and
Germany.
The Centre is located at the Middle East Technical
University (METU) campus, and is directly administered by to the
Office of the President.
The NDT section of this Centre has been continuing
its activities on ultrasonics, industrial radiography, magnetic
particle and penetrant testing, including training of NDT experts
for industry, and research studies for material characterization
and solving industrial problems.
BAM-Berlin, DGZfP, and SLV München have actively
contributed to the establishment of the Centre between 1988 and
1996 (providing training, and sending short- and long-term experts).
The testing laboratories of the Centre were accredited
by DAP-Germany according to EN 45001, and today these laboratories
are working in accordance with ISO 17025.
All staff and organizational units work based on
the quality policy of the Centre.
METU-Center and DGZfP (German NDT Society) have
played a very important role in the training of NDT experts and
extension of utilization of NDT techniques in Turkish industry.
Starting from 1988 more than 140 courses (4 methods,
2 levels) have been organized and run where more than 1600 persons
have attended these training courses. Following the changes in
the training and certification system in EU, NDT-Personnel Certification
Center was founded, and then, accredited according to EN ISO 17024
by Turkish Accreditation Council (TURKAK) in 2004.
