A list of methods used to detect flaws in rails: Ultrasound - the most popular method; Visual Inspection - Primarily using cameras to detect broken or cracked joint bars in bolted rail. Liquid Penetrant Inspection (LPI) - used for manual inspection of joint bars and rail ends. Eddy current inspection - great for surface flaws & near-surface flaws
The fluorescent penetrant is applied to the surface and allowed time to seep into flaws or defects in the material. The process of waiting for the penetrant to seep into flaws is called dwell time. Dwell time varies by material, the size of the indications that are intended to be identified and requirements / standards but is generally less ...
The E-T secondary electron detector can be used in the SEM's back-scattered electron mode by either turning off the Faraday cage or by applying a negative voltage to the Faraday cage. However, better back-scattered electron images come from dedicated BSE detectors rather than from using the E–T detector as a BSE detector.
Disadvantages include the detection of only surface flaws, skin irritation, and the inspection should be on a smooth clean surface where excessive penetrant can be removed prior to being developed. Conducting the test on rough surfaces, such as "as-welded" welds, will make it difficult to remove any excessive penetrant and could result in false ...
