摘要： PURPOSE:To form a sound welding bead by welding with directing welding torch to both welding proceeding and its opposite directions, gradually moving to the welding proceeding direction and stopping welding arc after welded with directing the welding torch between a backing and weld zone until the oval shape of crater becomes semicircle. CONSTITUTION:After completing joint welding from the leg part to belly part of facing rails 1, 1 with arranging groove, the enclosed arc multi layer welding of the head part of the rail 1 is executed with butting a backing 2 along the contour shape of head side of the rail 1. The arc of covered electrode 4 is directed to the opposite direction of the welding proceeding direction to weld, moving to the crater part in melted state generated near bead's end, moving in the welding proceeding direction, welding until the oval shape of crater becomes semicircle with butting welding arc between the weld zone and backing and then stopping the welding arc. This welding method is repeated for each layer to weld the head part of the rail 1.

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.

摘要： PURPOSE:To improve welding work and to prevent the occurrence of weld defects by using an electrode having coating material in the limited range and performing flat welding without carrying out slag removal at a part in the head where flat multilayer welding is performed. CONSTITUTION:At the time of performing flat multilayer welding of the head 7 and foot 9, the electrode coated with coating material containing 42-55% carbonate, a 13-23% metallic fluoride, 0.5-9.5% rutile and the balance consisting of an alloy additive and a binder on the periphery of a core wire is used. Further, CaO/CaF2 is regulated in the range of 1.3-1.7 and 15-25% coating material is applied with respect to the total weight of the electrode and slag is not removed for each pass or slag is removed for more than two passes and flat multilayer welding is performed continuously. By this method, it is made possible to manufacture a welded joint without weld defects with satisfactory welding workability and the working time is reduced.

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.
