1. A method of ultrasonic inspection flaw screening for weld inspection, comprising:
receiving scan data corresponding to different beam angles for different scan axis and ultrasound axis positions of an object including a weld, including a plurality of ultrasonic responses for each of a plurality of intersecting scan axis-ultrasound axis positions, wherein the scan axis is parallel to a long axis of a weld line of the weld;
for each of the plurality of intersecting scan axis-ultrasound axis positions, selecting a representative ultrasonic response with a maximum amplitude value from the plurality of ultrasonic responses for the respective scan axis-ultrasound axis position based on amplitude values of the plurality of ultrasonic responses;
merging selected ultrasonic responses for the plurality of intersecting scan axis-ultrasound axis positions to generate an image for weld inspection;
detecting a drift in a geometry of the weld in the image; and
straightening the merged ultrasonic responses to reduce or remove the drift in the image.
