Abstract:
A method of gas shielded arc welding railroad rails each comprising a base having a bottom, a vertically extending web and an upper head, said rails being longitudinally spaced apart to provide a base gap, a web gap and a head gap therebetween to be filled with steel to join said rails, said bottom of each said base having a laterally extending bottom edge and said base gap having a selected width between the bottom edges of the rails, said method comprising the steps of:(a) providing an elongated steel barrier plate having laterally opposite sides extending in the direction of said bottom edges, a width between said opposite sides greater than said selected width of said base gap, top and bottom sides, and a recess in said top side along each of said laterally opposite sides forming a barrier plate portion having a width corresponding to said selected width;(b) positioning said barrier plate for said plate portion to extend upwardly into said base gap at the bottom of said bases and for the recesses to receive the bottoms of the rails along the bottom edges thereof; and,(c) filling said base, web and head gaps above said steel barrier plate with a molten steel from an advancing filler metal electrode by a gas shielded electric arc welding process.
