NEW A31 and A32 Weld Series phased array probes and wedges simplify and standardize weld inspections with fewer designs, and improve signal-to-noise ratio. For manual inspections, real-time readings are essential to quickly position the reflected signal source with respect to the part’s geometry and/or probe location. To help mitigate this problem, Olympus developed a new tool that enables manual phased array inspection at temperatures up to 150 °C. The sound velocity in the wedge and components also varies with temperature, and this can affect focal law calculations and index point displacements, leading to positioning errors when locating indications. These wedges include mounting holes for Olympus’ Mini-Wheel encoder, enabling encoded inspection.

See full list on olympus-ims. The wedges are manufactured with an amorphous thermoplastic polyetherimide resin called ULTEM™. While ULTEM’s insulating properties are used to protect the probe from heat, heat dissipation is also important to enable a longer inspection period. Piezoelectric elements and internal connections in typical phased array probes are sensitive to heat and can be damaged by high temperatures. Relatively easy to machine, other Olympus wedge series could be manufactured with ULTEM material. Olympus’ high-temperature wedges enable simple and affordable manual encoded phased array inspection on components up to 150 °C as long as users keep in mind the maximum probe frequency of 5 MHz, the small negative frequency shift, small signal attenuation, and small positive refracting angle change. Ultrasonic signal attenuation and frequency shift must also be taken into account. After this period, no structural damage to the wedges or probes was observed.

When the ambient temperature is 25 °C, the wedge can by kept in contact with a 150 °C surface for a maximum of 10 minutes. In order to characterize and validate the efficiency of these wedges, laboratory testing was performed using the OmniScan MX2 flaw detector configured to perform a sector scan from 40° to 70° SW, which is typical for a weld inspection with phased array probes. To be used safely, the probes should not exceed a temperature of 60 °C. However, if an unlikely couplant gas auto ignition flash is of major concern, this couplant should not be used above the auto ignition temperature. Probes with different frequencies were tested to evaluate the center frequency shift caused by the use of the ULTEM material. 5 MHz probes, which shifted down to 5 MHz. 25 MHz probes remains the same, but the center frequency of 5 MHz probes shifted down to 4 MHz.

0 MHz Linear Array, 32 Elements, 19. As phased array probes heat up, the piezoelectric elements and their electrical connections can be damaged. 5-ztz Standard Phased Array Probe, 5. Note: The custom PA wedges listed above have been designed with specific application variables in mind. RA: Reference point to the indication in gate A.

The most significant center frequency shift occurred with 7. Should the 5l32-19.2x10-a11-p-2.5 application setup vary significantly from the expectation, these wedges may no longer be suitable and design changes may be recommended. The probe’s cable also has to be protected from the hot component being inspected. 2x10 mm Total Active Aperture, 0. Consequently, probes with frequencies over 5 MHz should not be used with ULTEM wedges. 5 m Cable Length, Tyco Zero Interface Connector _x000D_. Insulation, heat dissipation, and cooling are three important factors in wedge design to prevent excessive heat from reaching the probe elements. It takes an additional 10 minutes for the probe and wedge to cool.

Two wedge models were designed with this specific application in mind; both wedges are currently available for purchase—SA31C-ULT-N55S-IHC and SA32C-ULT-N55S-IHC. Our testing demonstrates that typical phased array probes completely fail if they reach 80 °C. At room temperature, the center frequency of 2. Olympus has developed a new wedge series that enables inspections on hot components up to 5l32-19.2x10-a11-p-2.5 manual 150 °C.

60 mm Pitch, 10 mm Elevation, A11 Case Type, Impedance Matching to Rexolite, PVC Sheathing, 2. Performing ultrasonic phased array inspections on high-temperature parts and components poses certain challenges. However, as heat dissipation is also dependen. Testing done 5l32-19.2x10-a11-p-2.5 manual with 5 MHz probes on a surface at 150 °C showed an increased center frequency shift down to 3 MHz. For additional information, please contact *Typical UT flaw and thickness applications use thin couplant films in an open environment where the small amount of gas formed can dissipate quickly. This material features elevated thermal resistance, strength, and stiffness due to its close to 200 °C high glass transition temperature. RA, PA, DA, and SA readings enable the user to accurately position the defect in real time during an inspection.
