The article presents ultrasonic test results concerning FSW joints deliberately provided with welding imperfections. The research aimed to determine the usability of ultrasonic tests in controlling the quality of FSW joints made of aluminium alloy 6082. The research-related tests involved the use of an EPOCH 600 defectoscope and a slant transducer. The testing procedure applied in the tests enabled the detection of welding imperfections and, consequently, the quality control of welded joints.
