With the rapid development of automobile industry, ductile iron component has become one of the most important components, which is the core components in many aspects, such as engine crankshaft, wheel hub, etc., which will be subject to extremely complex loads. Therefore, the crankshaft R region is particularly prone to fatigue cracks, which requires us to continuously strengthen the internal defect detection technology. With the development of detection technology, conventional ultrasonic technology has been unable to meet the needs of society. Through electronic scanning and acoustic beam deflection focusing, we gradually improve the Ultrasonic phased array detection technology (hereinafter referred to as UPADT), which can better realize the detection of automobile ductile iron components. UPADT is a kind of ordered excitation to the beam element, which can realize the deflection and focusing of the sound beam [1]. By combining sector scanning, electron scanning and DDF, we can achieve more beam incident modes, which will have faster detection speed and more accurate sensitivity.
