High-speed tubular inspection systems include a frame at least one magnetic flux generator contained in a coil annulus and a detector assembly each having inlet and outlet openings for passing a tubular member there through. The detector assembly has one or more magnetic detectors and one or more eddy current detectors configured to be spaced a first distance from the tubular member during an inspection. The detectors are each contained in one or more EMI detector shoes. A conveyor supports the frame and a drive mechanism configured to drive the tubular member through the coil annulus (or drive the coil annulus past the tubular member) at high-speeds.

Tubular member inspection apparatus, systems and methods for inspecting tubulars of a variety of diameters. An EMI inspection shoe includes a flexible, generally arcuate body having a leading end, a trailing end, a non-working major face, and a working major face. The leading end, trailing end, non-working major face, and working major face at least partially define an inspection zone therebetween. One or more magnetic flux detectors are carried by the flexible, generally arcuate body in the inspection zone. One or more pressure actuators removably attached to the non-working face are configured to exert pressure on one or more regions of the flexible, generally arcuate body in the inspection zone during an EMI inspection of a tubular, forcing the flexible, generally arcuate body to contort into a generally contoured shape as it passes over a contoured region of the tubular.

A method for producing a three-dimensional multilayer object produces a three-dimensional multilayer object by partially applying energy to a conductive powder and thereby melting or sintering and curing the conductive powder. The method for producing a three-dimensional multilayer object includes: applying energy to the conductive powder to melt or sinter the conductive powder, and detecting a flaw in a surface layer portion of the cured three-dimensional multilayer object by relatively moving a probe, which is disposed spaced apart from the surface layer portion, with respect to the surface layer portion. The method contains an excitation step of generating an eddy current in the surface layer portion and detecting a change in a magnetic field of the surface layer portion.

An aspect includes a vehicle that includes rail inspection sensors configured for capturing transducer data describing the rail, and a processor configured for receiving and processing the transducer data in near-real time to determine whether the captured transducer data identifies a suspected rail flaw. The processing includes inputting the captured transducer data to a machine learning system that has been trained to identify patterns in transducer data that indicate rail flaws. The processing also includes receiving an output from the machine learning system, the output indicating whether the captured transducer data identifies a suspected rail flaw. An alert is transmitted to an operator of the vehicle based at least in part on the output indicating that the captured transducer data identifies a suspected rail flaw. The alert includes a location of the suspected rail flaw and instructs the operator to stop the vehicle and to perform a repair action.

A probe device for a rotating head has at least one support arm that is mounted so as to rotate around an axis of rotation, at least one probe that is joined to the support arm, and at least one spring element that can be supported on the rotating head and engages at the support arm and that is provided for exerting a force on the support arm, which, as a result of this force, experiences a torque with respect to the axis of rotation. The support arm has at least one mount, which is concentric with the axis of rotation, for the spring element, which, when arranged on the mount, is bent at least in part around the axis of rotation. As a consequence, centrifugal forces that act on the spring element when the rotating head is in operation have no influence on the tension of the spring element.
