(Prior Art) Conventionally, the temperature measuring junction of a thermocouple is welded by manually inserting a wire having a diameter of 1 mm or less into a high-temperature heat source such as an oxyhydrogen gas flame or an electric arc. That is, hold thermocouple wires with different melting points, the minus leg and the plus leg, in your left and right hands, respectively, and touch them with their tips shifted by about 1 mm, and insert them into a high-temperature heat source to melt them, or It is made by making a molten spherical object, welding it by bringing the tip of the other unmolten wire into contact with it, and then taking it out and cooling it to solidify it. These methods not only require highly skilled techniques, but also cause variations in quality depending on the operator, making it difficult to obtain a homogeneous product. In addition, workers have to check the welding position and the size of the spherical object while looking at the strong light emitted during welding, so it is necessary to prevent visual impairment, which reduces work efficiency and reduces work efficiency. There were drawbacks such as the fact that only a maximum of 20 pairs could be made per day.
