An assembly includes a sensor configured to obtain a data scan of a joint. A controller is operatively connected to the sensor. The controller includes a processor and tangible, non-transitory memory on which is recorded instructions for executing a method for automated quality assessment of the joint. Execution of the instructions by the processor causes the controller to: obtain the data scan of the joint (via the sensor) and generate a first image based on the data scan. The first image is divided into a plurality of pixels having respective numeric values. The controller is programmed to identify a region of interest as the plurality of pixels from the first image with a respective numeric value greater than a threshold value (I0). The controller is programmed to assess joint quality based on a porosity factor (PF) determined at least partially from the data scan.
