Automated weld deposition coupled with the real-time robotic Non-Destructive Evaluation (NDE) is used in this paper.For performance verification of the in-process inspection system, an intentionally embedded defect, a tungsten rod, is introduced into the multi-pass weld.A partially-filled groove (staircase) sample is also manufactured and ultrasonically tested to calibrate the real-time inspection implemented on all seven layers pentair hose of the weld which are deposited progressively.The tungsten rod is successfully detected in the real-time NDE of the deposited position.

The same tokidoki hello kitty blind box robotic inspection system was then used to continuously monitor an intentionally-manufactured crack for 20 h.The crack was initiated 22 min after the weld ended and it grew quickly within the next 1.5 h.The crack growth stopped approximately after 2 h and no considerable change in the reflection signal was detected for the next 18 h of monitoring.
