Quantitative Evaluation of Brazed Joints in Flat Structure with Ultrasonic Inspection method
This paper describes the method to evaluate the brazed 10ints quantkatively through the ultrasonic C-scan images defined as three types that are overNl area,localized area and honeyconlb For each type of joint,different way is suggested to distinguish the defects The sottware used to calculatethe overall area ofthe brazed joint(S1)and the area of the defects(S2) is developed. On the other hand,the influence ofthe testhing parameters on the C-scan images is investigated to establish the inspection specification to assure the consistency and authenticity ofthe results It is concluded that using small focus transducer focused on the brazed Joints leads to opthllUlil images and the sensitivity for C-scan should be set with the artificial defect.
