摘要： Disclosed is an apparatus and method for forming thermal fatigue cracks in a test piece for performance demonstration of nondestructive testing. The apparatus for forming thermal fatigue cracks includes a heating unit, having a conductive member attached around the outer surface of a pipe test piece and an induction heating coil disposed adjacent to the conductive member; a cooling unit, having a cooling water pump for forcibly supplying cooling water to the inner surface of the pipe test piece from a cooling water storage source and a cooling water hose; and a control unit for controlling operation of the heating unit and the cooling unit. Accordingly, thermal fatigue cracks similar to actual thermal fatigue cracks occurring during the operation of nuclear power plants or processing industry equipment are formed in a test piece, thereby assuring effective performance demonstration of nondestructive testing.
