Abstract
A weld inspection system is adapted to inspect a weld of a work product via thermographic technology. The weld inspection system includes a heat source assembly, a thermal imaging camera, and a controller. The heat source assembly is adapted to sequentially direct a plurality of heat pulses upon the work product from varying perspectives and within a pre-determined time period. Thea thermal imaging camera is configured to thermally image the weld over the pre-determined time period and collect thermal imaging data of heat dissipation from the work product. The thermal imaging data is associated with the weld and the plurality of heat pulses. The controller is configured to control the heat source assembly and the thermal imaging camera. The controller includes a processor configured to receive and transform the thermal imaging data into a binary image for evaluation of the weld.
