Innovation Polymers in partnership with Materials Research Institute has developed a new and innovative phased array wedge design that improves phased array sectorial scanning of HDPE butt fusion joints. We have done this by incorporating a damping material with a low velocity refracting wedge made with Aqualink™ for pulse-echo testing.

The new design overcomes issues commonly associated with existing options in the marketplace, which include negative refraction when using hard plastics causing a weak signal. Large footprints limiting close approach when using water membranes. And easy adaptability to existing scanning systems.

Using a compact design and unique processing technique, we have been able to produce wedges that integrate with a number of widely used phased array probes.
