I would like to know actual methods based in Ultrasound techniques in order to check the quality of resistance spot welds. This question was posted several weeks ago, but I loosed all the useful information received from you due to a PC crash. Thank you in advance Ricardo Rios
An article in “Composites World Magazine” showcases Non
Destructive Testing of aero-structures
with Laser Shearography.
Over the years Dantec Dynamics has supplied many solutions for the
aerospace industry. Referring to specific customer projects
several of these cases are examined to outline the advantages of
using Laser Shearography for automated defect detection.
The conformability is obtained with a flexible membrane filled with water between the transducer and
the inspected component. The coupling between the membrane and the component requires a small quantity of water or couplant. The conformable wedge combines the acoustic performance of immersion technique with good coupling and low attenuation.
