Nanoclad Pipe Weld Repair, Systems and Methods

An in situ cladding apparatus for cladding within an installed pipe, the apparatus comprising:

• a coating collar around a portion of a main body of the apparatus, the collar configured to allow deployment of a cladding head through the collar;
• at least one cladding material reservoir capable of storing a cladding material coupled to the cladding head;
• an adjustable cladding chamber formed from an interior wall of the pipe, an external surface of the coating collar, at least a first circumferential wall and a second circumferential wall extending away from the coating collar toward the interior wall;
• a chamber controller configured to control dimensions of the adjustable chamber by controlling a position of at least one of the external surface of the coating collar, the first circumferential wall, and the second circumferential wall relative to the interior wall of the pipe;
• and
• wherein under control of the chamber controller the adjustable cladding chamber substantially forms a restricted cladding environment accessible to the cladding head.
