Case Study: Bonding Integrity in Bimetallic Steel Tubing
|
From Resonic NDT Systems
A number of samples were provided in 4 groups for evaluation of the interlayer bond integrity of stainless steel- tantalum-stainless steel tubing. These samples were examined with two types of RMEMATs (resonance mode electromagnetic acoustic transducers) each of several configurations; toroidal axially polarized shear wave and through thickness radially polarized shear wave transducers. The different transduction techniques provided the ability to introduce different types of stress fields into localized areas in the samples. This higher frequency resonance's produced by the flat or through thickness transducer introduces larger strains through the cross section thus providing information on the density or dimensional information and with more formal calculations the elastic constants of the composite core.
