P. Lemaitre et al., SUMMARY OF THE PISC ROUND-ROBIN RESULTS ON WROUGHT AND CAST AUSTENITIC STEEL WELDMENTS .1. WROUGHT-TO-WROUGHT CAPABILITY STUDY, International journal of pressure vessels and piping, 69(1), 1996, pp. 5-19
Within the framework of Action 4 of the third phase of the Programme f
or the Inspection of Steel Components (PISC III), three capability stu
dies on stainless steel welds have been conducted. The first capabilit
y study used a series of six wrought-to-wrought stainless steel assemb
lies that contained a number of flaws such as intergranular stress cor
rosion cracks, mechancial and thermal fatigue cracks and PISC type A f
laws. The second capability study used two wrought to-cast austenitic
steel assemblies that contained lack of fusion flaws and PISC type A f
laws. The third capability study used three cast-to-cast austenitic st
eel assemblies that contained lack of fusion flaws, mechanical fatigue
cracks and PISC type A flaws. In total, more than 25 teams from 10 di
fferent countries participated. A lot of information was obtained on t
he performance of the inspection techniques used with respect to detec
tion, 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 so
me of the more effective techniques and procedures, In Part I of this
work the main conclusions from the capability study on wrought to-wrou
ght austenitic steel welds will be discussed, The two other capability
studies are discussed in Parts II and III. Copyright (C) 1996 Elsevie
