Ultrasonic flaw detection has long been the preferred method for nondestructive testing in welding applications. This safe, accurate, and simple technique has pushed ultrasonic to the forefront of inspection technology. This refracted sound wave will bounce off a reflector (discontinuity) in the path of the sound beam. With proper angle beam techniques, echoes returned from the weld zone may allow the operator to determine the location and type of discontinuity.
Ultrasonic weld inspections are typically performed using a straight beam transducer in conjunction with an angle beam transducer and wedge.
This ultrasonic inspection may include the root, sidewall, crown, and heat-affected zones of a weld. The process involves scanning the surface of the material around the weldment with the transducer.
The most commonly occurring defects in welded joints are porosity, slag inclusions, lack of side-wall fusion, and lack of inter-run fusion, lack of root penetration, undercutting, and longitudinal or transverse cracks
