... can be measured by holographic interferometry; thus this method is too sensitive for welding. On the other hand, Moire interferometry is much more forgiving. Another interferometric technique called shearography seems to be more promising because the interference pattern is created simply by shearing...

... complex geometry such as a welded assembly, or is additively manufactured, or if the part has both metallic and nonmetallic or composite sections. There are terahertz (THz) imaging, infrared (IR) imaging and laser shearography (ST) techniques available that use discontinuity location and damage mode where...

... Fig. 1 (this specimen was coated in vibration dampening adhesive). Vibrography and dynamic shearography systems can also provide direct visualization of mode shapes, but these techniques generally require repeatable, harmonic motion, so they generally are not compatible with ultrasonic welder-based...
