: Dear NDT experts,
: could anybody give me information concerning the following NDT problem:
: I have to detect defects in soldered, non ferromagnetic components with curved surfaces. The 0.1mm - defects (pore spaces) at the soldered joints are located in a depth of up to 5mm below the accessible surface.
: A NDE method is required which is suitable for the integration in a manufacturing process. The concerning components vary very much in their shapes. So no scanning ultrasound or scanning eddy current method seems to be suitable.
: Thank you very much
: Thomas
We have an alternative NDT method that may be suitable for such components: acoustic resonant testing. Necessary is that the part "sounds" when you hit it. Our resonant testing equipement is designed for in-process testing (decision typically less than one second!). Have a look on our home page or please send us more information about your part.
Best regards
Ingolf Hertlin
