An inspection device inspects a joint-type outer joint member of a constant velocity universal joint that includes a cup section having a bottomed cylindrical shape and track grooves in an inner periphery thereof for torque transmitting elements, and a shaft section extending from a bottom of the cup section. The inspection device inspects the outer joint member, which is obtained through melt-welding on a cup member forming the cup section and a shaft member forming the shaft section. The inspection device includes a surface inspection unit to inspect for a defect which appears on a surface of the outer joint member due to welding, an internal inspection unit to inspect for an internal defect of a welded portion, and a recording unit to record an inspection result of the inspection. The inspection device is configured to efficiently perform in-line total inspection for the melt-welded joint-type outer joint member.

The invention relates to non-destructive ultrasonic testing of flat-bottom rails, laid on track, and can be used for detection of defects in tips of the rail foot on aluminothermic welded joints, performed by the intermediate casting method. During the ultrasonic testing of aluminothermic welded joints, at least two zones for ultrasonic testing were determined with selecting one of at least two zones on the weld bead (reinforcing bead) from the lateral surface of the tip of the rail foot. At least two specific zones are grinded on the weld collar (reinforcing collar) with creation of at least two flat areas, which are able to ensure acoustic contact. The ultrasonic transducer is placed on every flat area of the collar, which is connected to at least one ultrasonic flaw detector. Ultrasonic testing of weld is performed using at least one flaw detector Delta-method or echo-method. As a result of the invention implementation, there is no any blind zone in the base of the rail welded joint. The described invention ensures higher accuracy in detection of welds defects within the tips of the rail foot area. 2 z.p. f-ly, 8 il.

An inspection crawler, and systems and methods for inspecting underwater pipelines are provided. The system includes the inspection crawler having a housing with a first side, an opposing second side, a power source, and a controller. The crawler includes an inspection tool, at least two pairs of latching arms, each latching arm including a rolling element, and at least two pairs of driving wheels. The system also includes at least one communication unit configured to communicate with the inspection crawler and to communicate aerially with one or more remote devices and, and at one sea surface unit. The inspection crawler can further include a connecting structure connecting the front and back portions of the crawler, and configured to elongate and shorten the inspection crawler.

A system for underwater inspection including an inspection crawler are provided. The inspection crawler includes a housing having first and second sides, a power source, a controller, an inspection tool, at least two driving wheels, and a moveable center of gravity. A method for traversing a weld joint with the inspection crawler having a moving mass is also provided. In the method, the crawler is parked proximate to the joint, and the mass is slid along a slide rail to the second end of the crawler distal to the joint. The first end of the crawler is then propelled over the joint and the mass is slid to the center of the crawler. A center portion of the crawler is then propelled over the joint and the mass is slid to the first end of the crawler. The second end of the crawler is then propelled over the joint.

A method is disclosed to extract meta-data held in a weld scan data file and from such data determine whether the testing data is acceptable for review. A series of configuration parameters held in the scan data file are analyzed for inconsistencies and a select set of parameters are reviewed for codes and industry accepted standards compliance with recorded scan data. Additional qualitative tests may be implemented on the scan test file and unacceptable results may also provide guidance to the weld inspector as to whether continued review of the scan data file is worthwhile. Such consistency testing avoids wasteful activities reviewing a flawed weld scan data file and provides signals to operators to avoid the processing of such a file by weld scan analysis software when such processing will not result in successful assistance to a weld inspector.

A scanner assembly for pipeline inspection, having a pipe mounting section and a scanner frame which is laterally displaceable with respect to the pipe mounting section.

A process is disclosed in which a computing device reads electronic data from an ultrasonic scanning probe and processes that data in real time to determine if any potential weld defects are encountered as the probe head moves along scanning the weld. The method receives weld scan data in the form of scanning slices and determines if any of the encountered indications match a predetermined criterion. The process utilizes a moving scan data window of scan slices and processes each window for indications of weld defects. The processing of the data window is optimized using a rule-based, indications counting set so that any found defect indications triggers the issuance of a signal to an operator, in various forms, such as activating a marking module, issuing an alert signal, or printing a report.

A system provides for the calculation of the penetration depth of a weld in an orthotropic steel decking system. Weld scan section data is accessed and each scan section along the weld seam is processed to find the amount of penetration as a percentage of the thickness of the rib leg metal at the weld location. The amount of penetration is calculated by finding ultrasonic reflections recorded as voxels that have the greatest magnitude within an area of contiguous magnitudes and then determining the location of those voxels relative to the weld geometry and distance along the thickness of the rib leg steel. A report for each section scan and the entire weld seam may be generated for review by a weld inspector that allows for spot inspections of specified areas along the weld seam for possible weld remediation.
