USING ULTRASONICS TO CHECK RAILS TAKEN FROM THE TRACK

PROVERKA UL'TRAZVUKOM SNIATYKH S PUTI REL'SOV

Growing freight traffic density and higher axle loads and train speeds have increased rail shelling, chips, diagonal cracks and transverse fatigue cracks in rails; these now account for 70 to 84 percent of all rail head defects. Before such rails are used for relay purposes or for welding, rail head defects must be detected. This article discusses the advantages and shortcomings of existing and newly developed ultrasonic probes which may be used after rail has been removed from track for possible reuse. The standard equipment and procedure are described.
