An automated device for non-destructive testing for the detection of defects of a complex tubular product includes at least one ultrasound transducer arranged to emit an ultrasound beam having an emission orientation. The automated device further includes control and processing electronics configured to define at least one ultrasound burst parameter as a function of the longitudinal and/or circumferential position of the ultrasound emission means, so as to detect defects in the tube wall. The at least one parameter being chosen from the burst emission orientation, the gain or the position of the temporal filter.

Weld seam testing chain for testing a weld seam by means of ultrasound on two plastic tubes welded together at the ends, comprising standard chain links, wherein the standard chain links are hooked together to form the weld seam testing chain, and the chain can be lengthened or shortened individually, a sensor receptacle for accommodating the ultrasonic sensor, and an adjusting unit for the fine adjustment of the weld seam testing chain length, wherein the standard chain links have a hook on one side and a hook receptacle on the opposite side, thereby enabling the individual chain links to be hooked together.

A method, apparatus and program product may evaluate a packaging material to determine various metrics associated with the packaging material. A test apparatus may be used to evaluate packaging material using a take up drum capable of sensing containment force imparted upon the drum by packaging material applied thereto, and in some instances, simulated flaws may be formed in a web of packaging material to evaluate a packaging materials response to such flaws when under tension.

There is provided a method for evaluating the cleanliness of a steel material by an ultrasonic flaw detection method enabling rapid acquisition of highly reliable data. Ultrasonic flaw detection is performed to detect a flaw in at least one part in the range of 90% or more and 100% or less of a steel material (for example, round bar 2) at a radial position where the center of the steel material is set as 0% and the surface is set as 100%, and then the cleanliness is evaluated based on the dimension and the number of inclusions in the steel material obtained by the ultrasonic flaw detection.

A damage evaluation device includes: a phased array probe that irradiates an ultrasonic signal from a surface of an inspection metal toward an inside of the inspection metal and detects a reflection signal reflected in a predetermined region inside the inspection metal; and an arithmetic processor. The arithmetic processor sets planes parallel to each other in an inspection region, calculates pixel data by quantifying the reflection signal from segments set in each of the planes; calculates a scattering degree of the pixel data, and evaluates damage of the inspection metal based on the scattering degree.
