摘要： PROBLEM TO BE SOLVED: To automatically retain the conditions of gas to fixed ones regardless of the change of the temp. of the outside air and to steadily form and retain flame. SOLUTION: In a thermal spraying method in which flame F of oxygen-fuel is used as a heat source, a thermal spraying material is melted by the flame F, moreover, compressed air is jetted from the circumference of the flame F, and the melted thermal spraying material is made into fine melted droplets, which are sprayed on the surface of a base material to form coating, the feed of the oxygen-fuel gas and compressed air is made into fixed value by a mass flow controller 40. The mass flow controller 40 detects the mass flow rate in the case the temp. and pressure of the feeding gas are changed even without executing their correction and controls the same in such a manner that the detected value is made the fixed one, so that, even in the case the temp. of the outside air is changed, the gas conditions are retained to the set value, and desired thermal spraying conditions can always be obtained. When automatically optimum conditions can be obtd. in this way, even in automatic thermal spraying by a robot, stable and homogeneous sprayed coating can be obtd.

摘要： PROBLEM TO BE SOLVED: To obtain a welding method for a metallic material in which welding can be carried out to a desired place in a short period of time by using an extensive high temperature weld metal produced by a chemical reaction between oxidized metal and aluminum without requiring a power source and a welder.
SOLUTION: In the welding method for a metallic material, when a part requiring repair is caused in a metallic material 1 by chipping or wear, it is restored by welding. In this case, a shell with a shape to be welded corresponding to the part requiring repair is produced, and is mounted on the metallic material to form a welding space 21 on the side of the metallic material. The surroundings of the metallic material and the shell are coated with a refractory material (mold 20). A high temperature molten metal 11 produced by a chemical reaction between oxidized metal and aluminum is received by a molten metal receiver 30 arranged directly below the same, and is thereafter filled into the welding space 21 inside the shell while fluidizing the molten metal. The part requiring repair is formed with the molten metal 11 filled by melting the surface on the side mounted with the shell in the metallic material 1 by welding.

摘要： PROBLEM TO BE SOLVED: To make it possible to easily and surely forming a thermally sprayed film on the inner peripheral surface having ruggedness of a small-diameter tube. SOLUTION: A compressed air stream A is passed to the circumference of a flame F formed by burning a gaseous mixture composed of gaseous fuel and an oxidizing agent. A thermal spraying wire 17 is supplied toward this flame F and a globule is formed by melting this thermal spraying wire 17 by the heat of the flame. While this globule is finely divided by the compressed air flow A, the globules are accelerated and are sprayed onto a step part 21 on the inner periphery of the small-diameter tube 20, by which the thermally sprayed film is formed on the surface of the step part 21. The thermal spraying angle 6 is made at an angle of 90 deg. or approximate to 90 deg. and the thermal spraying wire 17 is continuously supplied from the outer side of the compressed air A toward the flame F.
