Production weld quality assurance through monitoring of beam characteristics
This paper describes the development of a quality assurance tool for production electron beam welding. The BeamAssure probe system has been installed on a number of production and development electron beam machines. The hardware and beam characterisation are described. Close correlation has been found between beam characteristics and key weld attributes. The reduction of rework and the rapid diagnosis of equipment variation from its normal characteristics have made significant savings – annually in excess of £500k for the example described.
