Aspects of Practical Application of the Comson Flaw-diagnosis System

ABSTRACT The computer aided ultrasonic flaw-diagnosis system COMSON has been developed by VOEST-ALPINE AG and KRAUTKRAEMER during the years 1985 to 1987 to on-site applicability. The socalled Basic-System, containing hard- and software for flaw-classification in butt-welds is now available on the market. After a short repetition of the leading characteristics of the COMSON technology the paper will report the major aspects and results of previous practical application with special respect to a round robin test, carried out by a number of operators on a series of different weld flaws, to verify COMSON system liability.
