Eddy-current testing device for metal tubes which are bent at least locally |
摘要 |
The eddy-current testing device operates by translational motion of a probe within the interior of tubes to be tested. The probe comprises in succession from front to rear in its direction of normal translational motion a front guiding member, a coil-carrying member and a rear guiding member connected together by an elastic means which tends to maintain these three members in aligned relation. At least the coil-carrying member has maximum transverse dimensions which are smaller than the internal diameter of the tube. An emitter-receiver coil of the probe is connected electrically to an external supply and scanning system by means of a cable which is secured mechanically to the rear guiding member.
