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.

Abstract: A method and apparatus for ergonomically supporting a worker while performing a work operation includes an automatic guided vehicle capable of moving a seat carrying the worker between a first non-work position relative to a work piece and a second work position at which the worker performs the work operation. The automatic guided vehicle includes controls to enable the worker to ergonomically position the angle of a seatback relative to a seat bottom and the height of the seat relative to the automatic guided vehicle for ergonomic support of the worker while performing the work operation. Under program control, the automatic guided vehicle is movable from one work position to another work position and/or back to the non-work position.
