Lamb wave ultrasonic evaluation of welded AA2024 specimens at tensile static and fatigue testing

Mechanical state assessment using lamb wave technique in static tensile tests

“…The AW1E12G-190EFL1Z piezoelectric discs used as transducers were adhesively bonded to the surface using 3M Scotch Weld DP105. The ultrasonic technique used during tensile testing is described in details in [6]. There was a 100 signals averaging used to increase S/N ratio.…”
