ABSTRACT:
A method of repair of an article incorporating the application of considerable thermal energy, e.g. a welding operation, requires heating of the article both in the repair area and surrounds wherein the heating of the repair area and surrounds is carried out by flexible heating mats and wherein fixing means are used to securely fix the heating mats to the article, which fixing means may readily release at least a part of the heating mats whereby that part may be folded back or otherwise removed from the repair area to allow the repair step to be carried out. After repair, that part of the heating mats removed from the repair area may be replaced.
