A method of repairing a weak spot (7) in the wall (3) of a vessel (1), which method comprises (a) securing at least one support element (2) to the wall (3) of the vessel (1) in the neighbourhood of the weak spot (7), wherein the ends of the support element(s) (2) are fixed to the wall (3) of the vessel (1); (b) covering the surface of the wall (3) around the weak spot (7) by means of a weld overlay in overlay area (13): (c) causing a support element (2) to elongate by an amount which balances the thermal expansion caused by the welding; and (d) removing the support element (2) after the welding has been substantially completed.
