PRE-REPAIR DIAGNOSIS OF THE FINGER METAL OF THE DRAW CHAIN BY ULTRASOUND
(pp. 48-52)

Abstract. The work presents a technique of diagnostics of fingers of a draw chain with the help of ultrasound, based on control of metal damage. The procedure of detection of fingers with maximum damaged metal is described. It is proposed to introduce in the practice of pre-repair diagnostics a non-burdensome procedure of sound attenuation control.

Keywords: ultrasonic control, finger of the draw chain, attenuation coefficient.
