ABSTRACT:
A method and system for detecting weld signatures from an ultrasound scan data obtained from scanning a pipeline is provided. The method includes a step for mapping multiple amplitude responses from the ultrasound scan data, each amplitude response being representative of a respective sensor signal. Continuous amplitude responses are located from the amplitude responses and corresponding signatures are identified for the continuous amplitude responses. The method also includes a step for tagging the corresponding signatures as weld signatures.
