Progress in The Field of Non-Destructive Testing Through The Use of Ultrasonics

Source

The Reflectoscope is widely used in various types of work at Douglas Aircraft Co., Inc. In some applications, contact scanning is the only practical way of doing a job. Obviously, a railway maintenance inspection would not require an axle to be removed from a car and put in a tank for underwater scanning. In pipe line work a tolerance for surface cracks is established and contact scanning with the aid of a shoe works satisfactorily. Ingots may be more conveniently tested for gas holes and cracks by contact methods.
