The removal of the impuri-ties is an important matter as they not only weakenthe weld but also clog the welding torch. Thiswelding of the rails imparts to the joint the requisiteamount of rigidity to resist flexure stresses. No partof the rail is shunted by the bonds so that the currentdistribution is practically as uniform throughout thejoint as in the solid rail. This adds materially to theconductance and is accomplished with the use of a smallweight of copper. ! 4Hv=zr; \ 1 ,/t-Wildcd Area 1 \L Ruil to be Cut out and Filled in bvOxy-AcLtyleue or Metulic SIDE VIEW AND CROSS-SECTION OF THIRD RAIL SPLICE AND BOND
