Review of Phased Array Ultrasonic Testing Technology for Bolt Crack Defects
Bolt is one of the most common fasteners.It is easy to produce crack defects due to stress,corrosion and other effects,which may lead to bolt fracture.Therefore,it is necessary to detect bolts.Phased array ultrasonic testing has many advantages such as high sensitivity,high signal-to-noise ratio,and easy identification of defects.Therefore,phased array testing is preferred when testing bolts.Based on the analysis of bolt defects,this paper summarizes the methods of bolt detection by phased array detection technology,which can accurately detect defects and reduce accidents.
