OKOndt Railroad Axle Immersion Testing System

Overview

The AXLE-4 System is designed for automated ultrasonic inspection of railcar wheel axles during production and after repair. The system uses the immersion technique to find all kinds of defects in railway axle bodies according to RD32.144-2000, EN 13261, М101, DSTU 31334 & BN 918275. Able to examine machined or semi-machined axles during their production and can be either integrated into the production line or operated as a stand-alone inspection station. Design of the system is compact and ergonomic.

Features

• Ultrasonic testing is automatically performed from the radial surface by immersion technique
• Axle to be tested is fully placed into the immersion tank where it is rotated by central clamping devices. Scanning is performed with linear motion of the UT scanner along the axle
• The system estimates equivalent sizes and depths of the defects
• Axle is inspected along its entire length, except for dead zones in center hole and bolt hole regions
• The testing facility has its own closed-circuit system of immersion liquid intake, supply and purification
• Conforms to RD32.144-2000, EN 13261, М101, DSTU 31334 & BN 918275
