本文介绍了允许未焊透和要求焊透的两种“T”型角焊缝的超声波探伤法。允许未焊透的“T”型角焊缝采用横波从翼板上探测。要求焊透的“T”型角焊缝则采用横波和纵波两种方法,以探测不同部位的缺陷。
This article describes an ultrasonic flaw detection method that allows for two “T” fillet welds that are impermeable and require penetration. Unfilled “T” fillet welds are allowed to be detected from the wing using shear waves. Requires penetration of the “T ” fillet weld is the use of transverse and longitudinal wave two methods to detect defects in different parts.
