Abstract
The visualization system for inner defect was established using Laser-ultrasonic in-process testing (LUT) technique and Synthesis Aperture Focus Technique (SAFT). The in-process quality control system realized the improvement of weld quality and the efficiency upgrade of welding operation and was applied to thick walled pipe welding to confirm the availability of this system for practical purposes.
