ABSTRACT:
A method of gas shielded arc welding steel railroad rails spaced from each other to define a longitudinal gap comprises the steps of providing an elongated steel barrier plate across the gap at the bottom of the spaced rails, and filling gap above the barrier plate with a molten steel from an advancing filler metal electrode by a gas shielded electric arc welding process. The barrier plate has a central portion received in the gap and longitudinally extending recesses laterally outwardly adjacent to the central portion and which underlie the bottoms of the rails at the bottom of the gap.
