Inspection of curved components such as longitudinal welds can be difficult using Phased Array Ultrasonic Testing (PAUT) and Total Focusing Method (TFM). For one, the curvature of the front surface implies using wedges adapted to ensure good coupling is obtained. The curved backwall also presents a challenge as ultrasonic waves will reflect off a convex surface making it difficult to define a proper scan plan. The instrument delay law calculator and imagery must consider these curvatures to send the acoustic energy in the right direction and reposition echoes correctly. In this blog, we present the various tools available with Capture™ data acquisition and analysis software to allow the inspection of longitudinal welds.
