Within the third phase of the programme for the inspection of steel components (PISC III) 3 capability studies on stainless steel welds have been conducted. The first capability study used a series of 6 wrought to wrought stainless steel assemblies that contained a number of flaws such as intergranular stress corrosion cracks, mechanical and thermal fatigue cracks and PISC type A flaws. The second capability study used 2 wrought to cast austenitic steel assemblies that contained lack of fusion flaws and PISC type A flaws. The third capability study used 3 cast to cast austenitic steel assemblies that contained lack of fusion flaws, mechanical fatigue cracks and PISC type A flaws. In total more than 25 teams from 10 different countries participated. A lot of information was obtained on the performance of the inspection techniques used with respect to detection, false calls, depth and length sizing. Different flaw categories were considered to identify those difficult to detect. Furthermore an analysis at the level of techniques was performed which identified some of the more effective techniques and procedures. In Part I of this article the main conclusions from the capability study on wrought to wrought austenitic steel welds is discussed.
