Analysis of Low-Amplitude Indications in Ultrasonic Tests of Thick-Walled MAG-Welded Butt Joints

Ryszard Krawczyk

The article presents an attempt at the clarification of low-amplitude indications, i.e. below the level of assessment, frequently detected in ultrasonic tests of welded joints. The above-named indications, non-evaluable in accordance with requirements of related standards used in ultrasonic tests, are often present in MAG-welded joints. The attempted clarification of the above-named exemplary indications required the performance of tests involving thick-walled MAG-welded butt joints.
