Therefore, a butt weld is made as follows:The rails are left in contact end to end, but the lip is cut off to obtain a symmetri-cal section and the base and web are also cut away with oxy-acetylene for a gapof 34 in. The second order of Thermit Welds was installed by our own menin 1914 during severe winter weather (10 deg. above zero) and atnight. Some twenty-five welds were made under these conditionsin old rail section 404 on the Bowery between Chatham Square andBayard Street. There have been no breaks to date. Continue the Installation.
