Abstract

A method of creating a weld to connect a first element to a second element, said elements being arranged in a wellbore (1) containing a wellbore fluid, is provided. The method comprises selecting a welding path along which the weld is to be created, selecting a volume portion of the wellbore, in which selected volume portion said path is located and sealing said selected volume portion from the remainder of the wellbore volume, and providing pressure control means (12, 16) for controlling the fluid pressure in said selected volume portion. The pressure control means is then operated so as to reduce the fluid pressure in said selected volume portion to a selected pressure at which the weld can be created, and the weld is created along the selected welding path.
