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.

摘要: A seal-packaging machine for a food container is proposed. The seal-packaging machine includes: a tray for loading a food-carrying container into the seal-packaging machine configured to move stably forward/backward while engaging with a -shaped guide by a “”-shaped guide rail; a heater unit driving support shafts operating the heater unit upward/downward and a heater unit driving portion support plate connected thereto operating upward/downward by two roller bearings and two eccentric cams contacting the same; a motor fixedly provided on a bottom frame to drive upward/downward the heater unit driving support shafts and the heater unit driving portion support plate of a heater unit driving portion; and a heater unit evenly operating upward/downward while keeping in horizontal along the four heater unit driving support shafts provided on four sides. The seal-packaging machine prevents defects due to imbalance of the heater unit, thereby guaranteeing an accurate sealing operation with a film.
