Abstract: A pipeline inspection assembly includes a test pipe including at least one weld and one or more synthetic weld flaws, and a pipeline inspection device mountable to the test pipe and movable relative thereto. The pipeline inspection device includes a detection device operable to detect the one or more synthetic weld flaws as the pipeline inspection device moves along a length of the test pipe. A performance of the pipeline inspection device is assessed based on a comparison of a detected characteristic of the one or more synthetic weld flaws and a known characteristic of the one or more synthetic weld flaws.
