Abstract: Longitudinally welded tubular member inspection and marking systems and methods. One system includes a longitudinal weld seam detection assembly and a marking assembly including an iris configured to be positioned about a longitudinally welded tubular member in an inspection position. The detection assembly includes a magnetic flux generator including a flux return and one or more sensors supported by the flux return and sensor supports. The marking assembly includes one or more marking heads. A computer is programmed to accept longitudinal weld seam detection signals transmitted from the one or more sensors and convert them into positioning information for the marking assembly to mark the longitudinal weld seam.
