Title of Invention

A METHOD OF GAS SHIELDED ARC WELDING STEEL RAILS

Abstract The present invention relates to a method of gas shielded arc welding steel rails each having a lower base, a vertically extending web and an upper head, the steel rails having laterally extending end faces longitudinally spaced apart to provide a base gap, a web gap and a head gap to be filled with steel to join said steel rails, each of the base gap, the web gap and the head gap have laterally opposite ends, said method comprising the steps of filling said base gap, said web gap and said head gap with a molten steel from a filler metal electrode by a gas shielded electric arc welding process, said filling of said head gap comprising the continuous and sequential moving of said electrode along longitudinally adjacent paths extending between laterally opposite ends of said head gap, each path having starting and ending ends at a different one of said opposite ends of said head gap, said electrode delayed in at the starting end of each said path for a preselected period of time.
