Non-Destructive Testing of Brazed Joints Made in Thin-Walled Austenitic Steel Pipes

Bogusław Ładecki, Łukasz Knysak

The article discusses methods used in the non-destructive testing of brazed joints made in thin-walled austenitic steel pipes using nickel and silver-based filler metals. Comparative tests involving the use of the radiographic and the ultrasonic method revealed the possibility of applying ultrasonic technique when defining quality levels in relation to brazed joints in thin-walled pipes. The ultrasonic method may serve as a cheaper alternative to the radiographic method in the automation of the non-destructive testing of the above-named joints in batch production.
