TOFD signals between L-L Backwall and L-Shear Backwall echo.
In a TOFD image it is recommended (ASME for example) a complete TOFD image including also the shear diffracted signals.
Where can I find clear and practical guidelines to make decissions and to understand the signals which appears between the Long- Long backwall echo and the Long-Shear backwall echo?
Thanks in advance.
