Ultrasonic angle beam standard reflector

摘要

This invention is a method for providing an impression profile in a reference standard material utilized in inspecting critically stressed components with pulsed ultrasound. A die stamp (10) having an I letter, reference numeral (36), is used to impress a reference material (50) having a surface (52). The die stamp is placed against the surface (52) and struck with an inertia imparting member to impress the I in the reference standard material. Upset (54) may appear on the surface (52) as a result of the impression and is removed to form a smooth surface (52). The stamping and upset removal is repeated until the entire surface area of a depth control platform (30) on the die stamp uniformly contacts the material surface (52). The I impression profile in the reference standard material (50) is utilized for reflecting pulsed ultrasonic beams as a means for inspecting ultrasonically.
