Evident ultrasonic spot weld transducers are specifically designed to provide optimal performance for nondestructive testing of numerous types of spot welds, including those used in automotive and industrial applications. Ultrasonic inspection of spot welds involves the analysis of what is known as the "ringdown" of sound within the weld nugget. Unlike many other direct measurement techniques, spot-weld 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 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 spot weld transducers allows them to be used with either a soft membrane captive water column or a hard tip delay line. Transducers, delay lines, and water columns are sold separately.
