Dual Linear Array (DLA) – Manual Weld Inspection - HIDDEN

Due to the material composition and grain structure, weld inspection of austenitic stainless steels and some other exotic material such as nickel alloys is difficult to perform with shear wave scans. Dual Linear Array (DLA) probes provide an adaptive and modular solution for weld inspection of material with high signal attenuation as they can significantly improve the SNR (signal to noise ratio) by focusing on the actual weld geometries. Low signal noise resulting from a Pitch & Catch setup combined with the beam steering capabilities of phased array technology is supplemented with an advanced wedge configuration to reduce the noise even further and allow the probes to be located closer to the actual HAZ (heat affected zone) and the weld.
