Abstract
A method for quantitatively assessing a quality of a weld joint includes positioning an electromagnetic radiation source adjacent the weld joint. The electromagnetic radiation source may be aligned to direct a beam of electromagnetic radiation onto the weld joint. A detector for capturing the electromagnetic radiation emitted from the electromagnetic radiation source may be positioned adjacent the weld joint along a side opposite the electromagnetic radiation source, such that the weld joint is positioned between the electromagnetic radiation source and the detector. A radiographic image of the weld joint may be obtained by directing the beam of electromagnetic radiation toward the weld joint and onto the detector. A weld joint quality rating may be determined for the weld joint based at least in part on the radiographic image.
