Patent attributes
A welding tool consisting of a tubular body having a lateral end and a pin end. The pin end has external threads disposed around an external circumferential surface of the pin end. The lateral end comprises an inner wall defining an orifice. Additionally, a heat proof shell is disposed circumferentially around the lateral end. The welding tool further includes a battery housing. The battery housing encloses a plurality of batteries which store energy. The welding tool further includes a welding element disposed on an inner surface of the orifice and an electric line. The electric line is coiled within the tubular body and physically contacts the welding element and is electrically connected to the plurality of batteries. The welding tool further includes a controller. The controller is capable of receiving and parsing mud pulse signals and controlling the release of stored energy from the batteries to the electric line.
