AUTOMATIC SUBMERGED-SLAG WELDING OF RAIL

The procedure of submerged-slag welding--a new automatic fusion welding of rails in the field--is described in this paper. The optimum wire compositions and welding conditions are determined in relation to micro hot cracking in HAZ, and the mechanical properties of welded rails are examined. Finally, the results of investigations of rails welded by a trial "welding car" are discussed. Based on the favourable results obtained of using this welding machine, it is expected to realize the full automatic welding of rails in the field in the near future.
