    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.

    Abstract: A method of laying a pipeline is described in which both internal and external weld passes are performed in order to weld together the pipe sections. The method includes arranging a pipe section adjacent to the end of a pipeline thereby defining a circumferential joint to be welded, performing an external weld pass, with for example GMAW—MIG torches, on the root of the joint to be welded during which weld material is deposited in the root of the joint to be welded, thereby forming a root weld, and then performing an internal weld pass, with for example a GTAW—TIG torch, on the root weld during which the root weld is melted and re-shaped. The method has particular application in relation to pipes clad with corrosion resistant alloy.
