Method, system and barrier plate for welding railroad rails

A method of gas shielded arc welding steel rails (10,12) spaced from each other to define a longitudinal gap (g) therebetween comprises the steps of providing an elongated steel barrier plate (432) across the gap at the bottom of the spaced rails (10,12), and filling the gap (g) above the barrier pl...

Beschreibung
Zusammenfassung:	A method of gas shielded arc welding steel rails (10,12) spaced from each other to define a longitudinal gap (g) therebetween comprises the steps of providing an elongated steel barrier plate (432) across the gap at the bottom of the spaced rails (10,12), and filling the gap (g) above the barrier plate (432) 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.
