AUTO BEAM OPTIMIZATION FOR PHASED ARRAY WELD INSPECTION

摘要

A method of computing optimal beam numbers of a phased-array ultrasonic weld inspection arrangement. The arrangement is for inspecting a weld that is within an area of interest that has a known dimension and with the inspection arrangement being at a known offset distance from the weld. The selection is such that operation of the at least one element provides sufficient information data for weld analysis. The elements extend along an ultrasonic transmission wedge of the arrangement that supports the extent of the elements at a wedge angle relative to the welded material. The method includes utilizing the dimension of the weld area of interest and dimension of offset of the inspection arrangement from the weld within calculation that yields the selection of the at least one element.
