The Sonatest DAAH Type 1 Wedge is a specialized ultrasonic testing accessory designed for use with Sonatest's DAAH (Detachable Active Array Head) series of phased array probes. This wedge is characterized by its Type 1 mechanical configuration within the DAAH range and features an external mount for the probe head.
Constructed from Rexolite (cross-linked polystyrene), a material known for its excellent acoustic transmission properties, low attenuation, and consistent sound velocity, this wedge ensures efficient transfer of the ultrasonic beam into the test material.
The key specification of this wedge is its 37 degree designation. This indicates the intended refracted angle of the ultrasonic beam within the material being inspected, typically steel, when used with a compatible DAAH probe. This specific 37-degree angle is chosen for particular ultrasonic inspection techniques, often employed with shear waves to detect and characterize flaws with specific orientations within the test piece, such as in weld inspections or general flaw detection in metallic components.
Being part of the DAAH system, this wedge benefits from the advantages of a detachable probe head, which can offer cost savings for maintenance and replacement, as the cable is separate from the more expensive array.
