Spotweld Transducers Olympus NDT ultrasonic spotweld transducers are specifically designed to provide optimal performance for nondestructive testing of numerous types of spotwelds, including those used in automotive and industrial applications. Ultrasonic inspection of spotwelds involves the analysis of what is known as the “ringdown” of sound within the Top Row: Transducer, Water Column, Membranes weld nugget. Unlike many other direct Bottom Row: Transducer, Delay Line, Delay Line Retainmeasurement techniques, spotweld ing Ring inspection looks at the characteristics of the multiple echoes returned from sound energy ringing within the weld nugget. Echo spacing, sound attenuation, and intermediate echo detection are some of the indicators of weld quality that are analyzed by trained inspectors. Our new Panametrics-NDT transducers have excellent signal-to-noise ratios due to broadband design, which is critical for distinguishing good welds from poor welds. These transducers are available in a multitude of sizes in 0.5 mm increments to ensure that the proper transducers are available for a variety of weld nugget sizes. Element sizes are engraved with both English and metric units for worldwide use. The versatile design of these spotweld transducers allows them to be used with either a soft membrane captive water column or a hard tip delay line. Panametrics-NDT transducers, delay lines, and water columns are sold separately. HARISONIC® Olympus NDT also offers a series of PVDF (polymer) transducers from the Harisonic line specifically for use with custom captive water column systems. These polymer transducers are very high resolution transducers due to the very broad bandwidth of the PVDF elements. These Harisonic probes are only for use with captive water columns, which come standard with the purchase of the transducer. Ultrasonic spotweld inspection can quickly and nondestructively provide valuable information about weld quality.
