Flash butt welding method of rail steel
A welding method is a method for subjecting a pair of track rail steels to flash- butt welding, which is provided with a preheating step for causing a current to flow for a predetermined time period in a state in which the welding surfaces of the pair of the track rail steels are forced into contact with each other, and heating the vicinity of the welding surfaces by means of resistance heating, a previous flash step for partially generating flash on the welding surfaces, and heating the welding surfaces by means of the resistance heating and electric-arc heating of the flash, and a later flash step for further generating the flash on the entire welding surfaces, and uniformly applying heat to the entire welding surfaces by means of the resistance heating and electric-arc heating of the flash, wherein the later flash speed in the later flash step is 2.1-2.8 mm/sec inclusive.
