Abstract

See full text

A method for evaluating a weld in a formed object includes performing a contact mechanics test of a first region that includes the weld and storing one or more corresponding weld surface mechanical property measurements, performing a contact mechanics test of a second region that excludes the weld and storing one or more corresponding base material surface mechanical property measurements, determining a relative difference in the weld surface mechanical property measurements and the base material surface mechanical property measurements, determining one or more weld width measurements on the exterior surface of the formed object, and evaluating the weld based on the determined relative difference in the weld surface mechanical property measurements and the base material surface mechanical property measurements in relation to the determined weld width measurements in order to provide an index of weld quality that is traditionally measured through a destructive test or examination.
