Abstract:
A method of gas shielded arc welding steel rails each having a lower base, a vertically extending web and an upper head, said 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 rails, each said base gap, web gap and head gap having 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 said head gap comprising continuously sequentially moving said electrode along longitudinally adjacent paths extending between the laterally opposite ends of said head gap each said path having starting and ending ends at a different one of said opposite ends of said head gap, and delaying movement of said electrode at the starting end of each said path for a preselected period of time.
