Automatic Rail Welding Seam Flaw Detector

The automatic rail welded joint ultrasonic flaw detector is applicable for the production line of 500m long rail-welding bases. The equipment is able to detect flaws using 5 methods that cover all of the relevant components. It can perform full section ultrasonic scanning and detection for welding seams automatically.

  • Product Features
  • The automatic rail flaw detector adopts advanced multi-channel technology for rail welding seam flaw detection.
  • Operating time takes less than 2 minutes to detect any problematic flaws in the rail weld seam.
  • Type B display for flaw estimation.
  • Fully retraceable detection with a data playback function for careful analysis.
  • The machine is equipped with an online rail welding seem detection unit to provide seamless connection with the rail production and transfer line.
  • Automatic positioning and auto-coupling are utilized to achieve maximum precision during operation.
  • 5 different flaw detection methods are used to cover all relevant flaw possibilities.
