ABSTRACT:
A method of and apparatus for the non-destructive evaluation of welds joining metal bodies employing infrared thermography; the method comprising the steps of applying thermal energy to a weld and observing temperature differentials that occur on the weld's surface. The apparatus comprises a device for applying thermal energy to welds being inspected; a device for scanning the weld surface for infrared radiation being emitted therefrom; a device for capturing the emitted radiation and converting it to a signal representative of the thermophysical characteristics of the weld; and a device for visually displaying the signal in a form suitable for interpretation.
