【Abstract】 In this paper the principle of non-destructive testing of the tubing- tube sheet explosive welding in a heat exchanger using a wide band short pulse ultrasonic technique and some problems in designing the structure of the small-diameter immersion probe search unit inserted in the inner diameter of the welded tubes are discussed.The principal reaserch experiment results of s.s.-steel,s.s.-s.s.,Ti-s.s, andZr-s.s, tubing-tube sheet explosive bonding quality are described.更多还原
