  • Patent number: 10345266
    Abstract: A method and system for the ultrasonic non-destructive testing of joints in plastic pipes using A-scans. A hand-held ultrasonic transducer is used to perform an A-scan and a comparison made on a response from the interface region of the joint used to determine a quality of the joint. Levels of result can provide a binary output to give an indication of whether or not a defect is present in the joint. Comparison techniques are described. Tests for coupling efficiency and performance are described making the system useable by an unskilled technician. The system finds application in fault detection on electro-fusion welds in plastic pipe joints.

    Abstract: In a butt-welded joint structure in which the entire peripheral edge or both end sides of the abutting surface are welded, first and second cutouts for determining insufficient penetration and determining excessive penetration are formed. After butt welding, ultrasound is beamed onto each of the first and second cutouts of the joint structure and the reflected wave is measured. The acceptability of the weld penetration depth is thus determined on the basis of both of the reflected waves. This determination is performed on the entire peripheral edge portion or both end side portions of the butted face between the welded materials, and the acceptability of the weld penetration depth of the corresponding portions is inspected.

A compression wave is generated within the transducer structure. The compression wave is reflected on a reflecting surface of the transducer structure to form the tension wave. The tension wave is directed through a test object in a desired direction using a configuration of the reflecting surface relative to the test object.

    Abstract: A joint structure by welding includes a butted part between facing surfaces of a first member and a second member and two-stepped clearances adjacent to the butted part, and a weld bead that is melted from a joint of the butted part which is positioned on an opposite side of the two-stepped clearances into the two-stepped clearances is formed in the butted part by welding. Other parts than the butted part are spaced apart from each other between the facing surfaces, and when a width of the weld bead is assumed to be “A”, a width of a first level clearance of the two-stepped clearances that is adjacent to the butted part is assumed to be “B”, and a width of a second level clearance of the two-stepped clearances that is adjacent to the first level clearance is assumed to be “C”, the relation of “B<A/2<C” is determined.

  • Publication number: 20140076053
    Abstract: A phased array ultrasonic probe may be mounted to a component to be inspected for wall thickness on an apparatus that includes a split ring adapted to be magnetically held in place on the component. In particular, the probe may be mounted to a carriage connected to the split ring in a manner that allows the carriage to rotate around the split ring while the probe is in operation. Between the probe and the component, a transducer shoe defining, by a flexible membrane, a cavity and an aperture. Conveniently, the construction of the flexible membrane allows wall thickness measurements to be acquired in portions of the component that have complex topography, such as welds. The apparatus is installed on an adaptor assembly for inspection of straight section of pipes. This adaptor assembly is not used in absence of straight section.

  • Patent number: 8667844
    Abstract: Presented is a system and method for testing the adhesion of coatings to substrates using an ultrasonic scalar. The system comprises a body, a flexible scalpel extending from said body, and a source of ultrasonic waves. The flexible scalpel applies pressure and ultrasonic waves to a coating that is removed when the adhesion of the coating to the substrate is substandard. The method comprises applying an flexible scalpel extending from an ultrasonic adhesion test device to a coating, applying ultrasonic waves through the flexible scalpel to the coating while moving across the coating, removing the coating if there is less than an acceptable adhesion of the coating to the substrate, and inspecting the coating to determine if coating was removed from the substrate.

  • Patent number: 8661905
    Abstract: Non-contact microelectronic device inspection systems and methods are discussed and provided. Some embodiments include a method of generating a virtual reference device (or chip). This approach uses a statistics to find devices in a sample set that are most similar and then averages their time domain signals to generate the virtual reference. Signals associated with the virtual reference can then be correlated with time domain signals obtained from the packages under inspection to obtain a quality signature. Defective and non-defective devices are separated by estimating a beta distribution that fits a quality signature histogram of inspected packages and determining a cutoff threshold for an acceptable quality signature. Other aspects, features, and embodiments are also claimed and described.

  • Patent number: 8660804
    Abstract: The invention relates to the non-destructive measurement of components, in particular the functional assessment of the bonding of cast-in parts, eg. in pistons for internal combustion engines. With such a measurement or functional assessment, it is a question of assessing the function and completeness of the bonding between the base material and the material cast in or otherwise joined. The quality of the component or its suitability for a specific purpose can thus be assessed and/or quality monitoring of the production process, e.g. in the foundry or during production, can take place. According to the invention, this purpose is served by a multi-stage correction procedure, wherein the measured values ascertained by means of a suitably devised measuring arrangement and method, e.g.

    Abstract: Apparatuses and methods are disclosed for determining whether a structure of bonded layers includes locations where the layers are weakly bonded. Embodiments include evaluating the frequency response of the structure in response to vibrational inputs. Alternate embodiments include evaluating the non-linear response of the structure using a modal analysis. Further embodiments include obtaining the vibrational information with an accelerometer contacting the structure, while additional embodiments include exciting the structure with an impact force, which may be applied at multiple locations on the structure's surface. Still further embodiments include performing a MAC, COMAC, and/or FRF analysis. Still other embodiments include varying the amplitude of the input vibration. Additional embodiments locate the areas of weakened bonding. Still other embodiments include methods and apparatuses for simulating a laminated structure with defective bonding, such as kiss bonding.

  • Patent number: 8627722
    Abstract: Disclosed is a welding inspection method which does not require the inspector to be highly skilled, does not require waiting for the spot welded part to cool off, and with which the probe is not consumed or damaged. A probe temporarily mounted close to the welded part on the surface of a metal plate emits ultrasonic waves from an oblique direction with respect to the boundary surfaces between a plurality of metal plates. At this time, the probe is temporarily mounted at the position where the incident ultrasonic waves pass through the welded part at the boundary between the plurality of metal plates in an oblique direction with respect to the boundary surface. Also, a display processing means displays the intensity of the refrected ultrasonic waves. Alternatively, the display processing means displays the details of the detection result estimated based on the intensity of the reflected ultrasonic waves.

  • Patent number: 8578580
    Abstract: According to the present invention, penetrators can be adequately determined as flaws. In particular, a welded zone of a pipe is subjected to ultrasonic flaw detection at least in a pipe axial direction, and the quality of the pipe is evaluated using observed values in units of a predetermined area in a pipe thickness direction and the pipe axial direction. The length of one side of the predetermined area is an ultrasound beam width or more and a pipe thickness or less. The quality of the pipe can be evaluated while shifting the predetermined area in the pipe axial direction by using an average value of the observed values within the predetermined area. The length of one side of the predetermined area can be made an ultrasound beam width or more and a pipe thickness or less.
