Flaw classification (determination of the flaw type) and flaw sizing (prediction of the flaw shape, orientation and sizing parameters) are very essential issues in quantitative ultrasonic nondestructive evaluation of various materials and structures including weldments. For performing of these tasks in an automated fashion, we are developing an intelligent ultrasonic evaluation system with a multi-axis portable scanner which can do consistent and efficient acquisition and processing of ultrasonic flaw signals. Here we present an effort to develop of this intelligent system which includes design of portable scanner based on work space analysis using computer graphics tools, acquisition and processing of ultrasonic flaw signals, image display and classification of flaws in weldments using neural networks.
