Abstract: A method of welding and apparatus for implementing the method are provided which employ inspection of a weld formed by the method of welding. The inspecting of the weld is provided by the inspection apparatus at an inspection location on the one or more welded substrates, with the inspection location at an elevated temperature above ambient, for instance wherein the elevated temperature is at least 180° C. above ambient or even at least 350° C. above ambient. In this way the inspection can be performed without the substrate needing to cool and faster inspection and faster weld remediation times are achieved.

Abstract: A method and apparatus for providing an inspection of a weld are disclosed wherein the method comprises: providing weld inspection apparatus in proximity with a weld on a substrate to be inspected; conducting the inspection, wherein the substrate is provided at an elevated temperature state above ambient temperature by heating during the inspection, the conducting of the inspection including: emitting an ultrasound wave into a volume of the substrate and weld; receiving at least a part of the ultrasound wave back from the substrate and weld, thereby acquiring multiple signal sets; then processing one or more of the multiple signal sets to provide weld inspection data; wherein the processing includes a correction for temperature distribution within the volume of the substrate and/or the weld, at the elevated temperature.
