Project Description

Manufacturing of testblocks with embedded defects & flaws for NDT/NDE qualification programs

Test blocks & specimens with realistic defects and flaws

• Uddcomb International AB manufactures testblocks with realistic defects in welds and adjacent base metal materials.

• Test blocks are widely used in the nuclear industry, notified bodies, NDT training schools, offshore industry.

• Test blocks are manufactured as OPEN test blocks where the defect characteristics are known to the user or as BLIND test blocks where the defects are unknown to the user. In the case of BLIND test blocks the user will have to find the defects, validate and/or develop NDT methods and NDT equipment for component inspections.

• The character of our realistic defects like IGSCC, IDSCC, lack of fusion, and slag inclusions follow the requirements of ENIQ.
• The defects are not limited to length and depth.
• The defects can be tilted and follow HAZ or other expected direction.
• The defects can be embedded.

Manufacturing of testblocks with embedded defects & flaws for NDT/NDE qualification programs

Manufacturing of Testblocks & Test specimens with realistic defects and flaws

The international breakthrough for test blocks came with extensive deliveries of test blocks for the Sizewell B reactor in the UK during the 80s. Since then hundreds of test specimens have been developed and manufactured according to our clients specific requirements worldwide. Uddcomb has unique experience and capability regarding the development and implantation of defects in test blocks/test specimens.

Typical defects that are manufactured and implemented are:

• Geometric defects
• Implants
• Weld solidification cracks
• Lack of fusion
• Mechanical fatigue cracks
• EDM notches
• Weld solidification cracks – DAS182   (IGSCC / IDSCC)

  • Test blocks/test specimens based on Uddcombs proven technology have been used in the nuclear industry for +40 years

  • Manufacturing and deliveries of test blocks/test specimens worldwide

  • Research & Development of the next generation of testblocks to increase reliability in critical components, defect characteristics (material combinations, length, width, tilt, depth)

  • Unique technology for manufacturing of defects and test blocks with IDSCC and IGSCC

  • Dedicated workshop area and working routines for manufacturing of test blocks that contains highly sensitive information
