Abstract: A pipe weld repair structure adapted to seal leaks or cracks at a weld circumferentially disposed in a pipe. Includes at least two pipe clamp segments disposed around the pipe and connected together to form complete clamp. Each clamp segment defines two inner surfaces adapted to be in contact with outer surface of pipe when clamps are connected together around pipe. Each clamp segment defines an inner grooved recess disposed between inner surfaces and adapted to enclose a weld circumferentially disposed around pipe when clamps are connected together around pipe. Clamp segments define an internal diameter when clamp segments are connected to form complete clamp. Internal diameter is conventional fit around pipe while clamp segments are at sufficiently high temperature to cause thermal expansion. Internal diameter is a shrink fit around the surfaces of pipe after clamp segments are connected together while at sufficiently high temperature and subsequently allowed to cool to same temperature as pipe.
