Abstract:

In 2005, Transportation Technology Center, Inc. (TTCI) and Norfolk Southern Railway (NS) began a test of wide-gap welds (WGWs) at the eastern mega site near Bluefield, WV.

WGWs enable the repair of weld or railhead defects with a single weld instead of the typical rail plug-and-weld procedure that requires two welds. A defect limited to less than 2.75 inches in the longitudinal direction can be replaced with a single WGW.
