Abstract: A method for repairing a defective circumferential weld joint between two pipe sections in a pipeline is described. A weld excavation machine is used to remove a weld defect. The machine comprises a weld excavating tool and a tool guiding apparatus. The machine may be modular in form allowing the machine to be dissembled into discrete portable parts. The method includes arranging the tool guiding apparatus in fixed relation to the pipeline, guiding the weld excavating tool around the pipe and along the weld joint by means of the tool guiding apparatus and using the weld excavating tool to remove material from the defective weld region. An excavation may thus be formed having parallel vertical walls. The excavation is then filled with weld material by means of a welding apparatus.
