摘要： PROBLEM TO BE SOLVED: To make it difficult for copper to enter the grain boundary of austenite generated in a steel material such as a rail and prevent grain boundary cracking of a welding part due to repeated stress by composing a welding metal, which is generated with a thermit reaction and joints the steel materials, of an alloy including a copper element and a nickel element. SOLUTION: A nickel element in the welding metal is 5 wt.% or more but 60 wt.% or less. A copper element is added to a thermit agent in a condition of metal copper and copper oxide. It is preferable that the copper material is a copper-wire or a copper stranded wire, the steel material is a rail, and also the copper material is a rail bond. The nickel element is added to the thermit agent under the condition of metallic nickel and nickel oxide. A copper- nickel alloy may be added to the thermit agent. A substance including nickel may be added to a welding portion in a separate route from the thermit agent. Since quality of the thermit welding is improved, the steel material and the copper material can be welded at high quality, regardless of techniques of operators.

摘要： PROBLEM TO BE SOLVED: To reduce the generation of carbonic acid gas, to increase the safety of operation, and to increase quality.
SOLUTION: A combustion gas feeding part 1 is provided with an oxygen- hydrogen gaseous mixture generator 3, a carbon compound vaporizer 4 and a gas mixing chamber 5. The oxygen-hydrogen gaseous mixture generator 3 in the combustion gas feeding part 1 electrolyzes water to generate a gaseous mixture of oxygen and hydrogen. The carbon compound vaporizer 4 is used for stabilizing the flame of the oxygen-hydrogen gaseous mixture since the flame is not stabilized only in itself. The gas mixing chamber 5 mixes the oxygen-hydrgen gaseous mixture of the oxygen-hydrogen gaseous mixture generator 3 and hexane of the carbon compound vaporizer 4 so that their ratios reach a prescribed ratio, and feeds the resultant gaseous mixture into a gas burner 2.

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： PROBLEM TO BE SOLVED: To provide a gas-pressure welding method in which a fuel gas other than acetylene can be used without causing the deterioration of joining strength/joining quality, and a joining structure.
SOLUTION: The gas-pressure welding method is constituted so that the end faces of steel materials 1, 1 are butted against each other. It is pressurized for a prescribed period of time while maintaining initial pressure P
1 and heating the butting part with a gas flame such as hydrogen. After that, the pressurization of the initial pressure P
1 is interrupted and the residual pressure drops. The butting part is heated again for a prescribed period of time in a state of applying secondary pressure P
2 to the butting part when the residual pressure reaches the lower limit pressure P
0 . In this case, the secondary pressure P
2 is set to 1.2-4 times of the initial pressure P
1 .
