The information in this WRC Bulletin has been abstracted from several documents generated by the European Program for the Inspection of Steel Components (PISC)@ both PISC-II and PISC-III. Information was abstracted with the knowledge and consent of the PISC Management Board. The broad dissemination of the information is mutually valuable to both the nuclear and the non-nuclear organizations including fossil-fueled using the data.The information is equally relevant to non-nuclear users in fossil-fueled power plants@ petrochemical plants@ chemical plants@ etc. The users of this report should understand that this WRC Bulletin consists of several discrete reports@ each dealing with a specific material or component so that each Achapter@ is a separate report. Some parametric studies have a broader scope and relate to more than one chapter. The report attempts to address significant variables in the systems/components examined. Factors considered include the ultrasonic equipment variables influencing reliability of flaw detection@ location and sizing@ the value of supplementary UT techniques@ and the part the operator(s) play@ both negatively and positively@ in the detection and sizing of flaws and in the minimization of false calls. Topics include thick-walled ferritic sections@ manual and mechanized UT@ wrought and cast austenitic stainless steels including wrought-to-wrought stainless steel@ wrought-to-cast stainless steel and cast-to-cast stainless steel@ dissimilar metal welds and human factors. Publication of this document - WRC Bulletin No. 420 was sponsored by the Pressure Vessel Research Council of the Welding Research Council@ Inc.
