REDUCING INFLUENCE OF HUMAN FACTORS ON THE MANUAL ULTRASONIC WELD INSPECTION RELIABILITY

Authors Garri S. Passi, Yossi Shoef, Marina V. Kritsky


Abstract

Being under influence of human factors the low cost manual ultrasonic testing of welded joints can't compete with the expensive and hazardous X-ray or isotope inspection in many cases, despite the advantage of having highest sensitivity. To minimize such influence special exploration was performed and new I²-Sonic Manual Ultrasonic Testing Objectivization System was created. The main I²-Sonic concept is automatic on-line imaging and documenting two kinds of NDT data including operator's observing testing technology and his mistakes, and quality of object under test. Exploration results, I²-Sonic principles, and some other new concepts are discussed in the paper.
