1. A downhole tool for repairing a tubular disposed in a wellbore, the tool comprising:
a main body assembly configured to be positioned within the tubular;
a cladding feed assembly configured to dispose a cladding material at a defect area on an interior surface of the tubular; and
a laser head assembly comprising a laser head configured to direct a laser beam radially outward with respect to a central axis of the tool towards the defect area to thereby weld at least a portion of the cladding material to the interior surface of the defect area, the laser head assembly articulated to positionally adjust the laser head radially with respect to the central axis independently of the position of the tool to thereby adjust the distance between the laser head and the defect area while the tool and the laser head otherwise remain substantially motionless relative to the defect area, thereby selectively adjusting an area of incidence of the laser beam on the cladding material at the defect area.
