Material and Welding Technology

Ensure operational safety and availability of structures and technical facilities

Ensuring the operational safety and availability of structures, technical components and facilities is critical. Operating conditions may subject materials to mechanical, thermal or corrosive influences that can cause component failure. That’s why manufacturers and plant owners need to consider the type of materials, processing methods, welding techniques and procedures used.

Quality standards and detailed procedures for operation help to mitigate these issues by ensuring correct material selection, welding procedure, equipment usage and maintenance.

TÜV SÜD supports manufacturers in material and welding technology through testing, inspection and certification services for materials and processing methods, as well as for welding activities. We assess and certify materials, products and manufacturers in accordance to national and international standards to ensure the quality and safety of your components and industrial plants.

  • Our experts perform auditing and certification of manufacturers of materials and semi-finished products in accordance with AD-2000-W0, TRD 100, KTA 3201.1, KTA 3211.1, PED 2014/68/EU and EN ISO 9001:2008.
  • We provide certification for (EU) Regulation No. 305/2011 (CPR) as a Notified Body.
  • TÜV SÜD is an approved testing and inspection body for DVGW (initial certification and surveillance only).

Quality assurance

  • We support you with in-process inspection and quality control during component production in the plant and during assembly and installation.
  • Our services also include review of specifications and other manufacturing documents.

Failure analysis and corrosion assessment

  • TÜV SÜD provides failure analysis and evaluation of repair concepts based on various tests and analyses.
  • This includes fractography and energy dispersive micro scale analysis by Reflection Electron Microscope (REM), metallography, mechanical and technological tests, vacuum emission spectrometry, corrosion assessments and water chemistry analysis.

Welding services

  • We provide technical support on local and international standards requirements.
  • Our experts review welding documents and conduct production and final inspections of welded structures and components.
  • Our tests and certification of welding filler materials also form the basis for subsequent approvals.
  • Our auditing and certification of manufacturers and welding companies is carried out in accordance with AD-2000-HP0, TRD 201, KTA 3201.3 and KTA 3211.3, harmonized standards for pressure equipment, PED 2014/68/EU (module audits), EN ISO 3834, EN ISO 9001:2008, EN 15085-2, RID 6.8.2.1.23 in conjunction with EN 14025 and EN ISO 3834-2, and CPR 305/2011 in conjunction with EN 1090-1 (metal constructions) and EN 13479 (filler metals).
  • We also provide certification of welders, welding operators and brazers.

Non-destructive examination

  • In addition to assessment of NDE programmes and  qualification of NDE methods and personnel, we can conduct NDEs on your behalf.
