fatigue crack matrix array probe SCC stainless steel twin transducer ultrasonic testing weld
A twin matrix array transducer to make possible to detect and measure a flaw with test direction through weld of austenitic stainless steel has been developed. Each transducer performs as transmitter and receiver and has 2 lines and 16 columns array elements respectively. With this transducer depth measurement tests for cracks by stress corrosion cracking (SCC) and fatigue on austenitic stainless steel weld pipe specimens have been carried out.As the results: (1) Corner echoes and ti p echoes from SCCs ...
