摘要： PROBLEM TO BE SOLVED: To provide a cooling method for a rail welding structure, by which a cooling time can be shortened while a weld zone strength is maintained.
SOLUTION: This is a method for cooling a rail welding structure in which a pair of rail ends are oppositely faced through a weld zone and welded . The surface temperature of the weld zone is measured after thermit welding and, when the temperature becomes A
1 transformation temperature or below, the rail end is cooled by spraying water on the head of the rail which, being an end of the rail, is an unfused part. Subsequently, when the surface temperature of the weld zone goes down to 500°C or below, the weld zone is also sprayed with water and cooled.

摘要： PROBLEM TO BE SOLVED: To provide a method for welding a rail joint whereby the labor and time required for enclosed arc welding at the rail joint can be reduced and development of crack and damage to the web and the head of each rail at the joint can be prevented.
SOLUTION: Welding is performed not in the bottom areas of the rails 1, 1 at the joint but in the area of the joint from the web areas to the heads 1b, 1b of the rails 1, 1, so as to reduce the labor and time required for the enclosed arc welding at the rail joint. After the joint is welded, the webs 1c, 1c of the opposite rails 1, 1 are joined together by a joint plate 2. Because the joint plate 2 can resist a tensile force acting on the bottoms of the rails, cracking and damage to the web 1c and the head 1b of the rail 1 at the joint can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide a gas pressure welding method in which the oxide that causes the generation of defects of cracks, wounds or the like is decreased enough.SOLUTION: In the gas pressure welding method, at first, recessed parts 5 are each formed at end faces 2, 2 of two railway rails 1, 1 (step 101). Next, the two railway rails 1, 1 are butted by those end faces 2, 2 (step 102). Thus, the end faces 2, 2 of the railway rails 1, 1 are mutually touched at the centers 3, 3, and are mutually spaced at the peripheral edges 4, 4, and a gap 11 in which the recessed parts 5, 5 are combined is formed in a groove shape between the peripheral edges 4, 4. Next, those butting parts are heated by the combustion flame consisting of oxygen gas and acetylene gas while making the pressurizing force of a material axial compression direction act on the railway rails 1, 1. In the heating, the combustion flame is blown into the gap 11 between the end faces 2, 2 (step 103).

摘要： PROBLEM TO BE SOLVED: To provide a steel material gas joining method which can obtain a high joining quality, while preventing a complexity of operation, by relaxing a required polishing accuracy of the joining end faces. SOLUTION: After the end faces 1a, 3a of the steel materials 1, 3 are butt- welded at a given preliminary pressure, the welded portion is heated with a gas flame. When the preliminary compressed volume of the steel materials 1, 3 in their shaft directions reaches a given volume, the above preliminary pressure is released while keeping a relative positioning relationship of the steel materials 1, 3 fixed portions, and, when the butt welded portion reaches a given temperature, both steel materials 1, 3 are pressurized with a pressure equal to the preliminary pressure so as to carry out a compression until it reaches a given total compression volume.
