Phased array full matrix capture improved defect visualisation and sizing trial

To be launched: June 2008
Cost per Sponsor: £20 000, one payment
Project Leader: Colin Bird

Phased array inspection is now well established and has shown many advantages for a number of industry sectors. Due to increased computing power it is now possible to apply a relatively new ultrasonic technique, Full Matrix Capture (FMC). This technique has been developed at the University of Bristol (UoB) for a number of years and there have been several papers published on the basics of the technique. In particular, UoB has taken the technology to a level where it can be applied in the laboratory. This project proposes to independently evaluate the technique and explore its potential for industrial application.

The following are a selection of active projects. A full list is available on this website or from peter.oakley@twi.co.uk. Additional participants are welcome to join at any stage or to buy back the results from completed projects.

  • High productivity arc and laser welding of titanium and titanium alloys
  • Reliability of manually applied phased array ultrasonic inspection for detection and sizing of flaws
  • Exploitation of power beam welding of thick section steel for structural applications
  • Friction stir spot welding of high strength steels for transport industries
  • Acceptance criteria for pitting corrosion of CRA in oil and gas production environments
  • Definition of sour service limits for welded type 316l and cost effective CRAs
  • Design and use of dissimilar joints for subsea applications
  • Factors influencing the sour corrosion fatigue behaviour of C-Mn steel catenary riser welds
  • Raising the acceptance level for Ni in C-Mn steel welds for sour service
  • Sour corrosion fatigue behaviour of girth welded clad pipe
  • Sulphide stress cracking and preferential weld corrosion performance of welds between modified A707 and C-Mn SCR pipe
