Traditionally fusion welding of manufactured components ‎and quality control inspection of such welds are distinctly ‎separate processes in the supply chain, which ultimately limit ‎productivity, throughput and increase re-work. The concept of ‎combining both of these practices directly at the point of ‎manufacture offers the potential to produce superior, globally-‎efficient fabrications. This paper presents the results of a study ‎investigating such a strategy, where a multi-pass weld is ‎autonomously deposited and, in parallel, an autonomous ‎inspection is deployed for real-time Non-Destructive ‎Evaluation (NDE). A real-time sector scan is implemented after ‎each of 21 weld passes and in three inspection positions, i.e., ‎the first position is 50 mm from the weld start, the second ‎‎being in the center of the weld length and the last is 50 ‎mm ‎distance to the weld endpoint. ‎Only in the second position, an ‏intentionally embedded defect, a tungsten rod, is introduced ‎into the multi-pass weld to allow subsequent in-process ‎calibration and verification. Based on the phased array ‎inspection results, the tungsten ‎rod is successfully detected in ‎the real-time NDE of the deposited ‎position. Furthermore, the ‎reflection ‎due to the partially ‎filled groove is captured during ‎the ‎inspection of the filling ‎passes. ‎
