方法であった。Prior art and its problems Vacuum-sealing a chemical substance in a metal container involves filling the metal container with the chemical substance by vacuum impregnation, then placing the metal container in a vacuum welding chamber, and performing electron beam welding or laser welding. It is common to vacuum-seal the container. This work will be explained using a sodium-sulfur battery as an example. Figure 4 is + )
In the cross-sectional view of the IJ Umu sulfur battery, 1 is the cathode chamber metal container 2.
16 indicates a metal tube for vacuum impregnating sodium as the cathode active material 7 into the anode chamber metal container 4; 2, the solid electrolyte tube 5 is joined to the upper surface of the α-alumina ring 6 by glass soldering, and the anode chamber metal container 4 is joined to the lower surface of the α-alumina ring 6 by heat pressure. In such a sodium-sulfur battery, sodium as a cathode active material 7 is supplied from a metal tube 1, and sulfur as an anode active material 8 is supplied from a metal tube 3 by vacuum impregnation as shown by the arrows in FIG. 5(a). After filling,
The tip is sealed by applying pressure as shown in Figure 5 (b), and vacuum sealed by electron beam welding or laser welding in the vacuum welding chamber as shown in Figure 6 (C). This method is not suitable for mass production because it requires a lot of man-hours to take things in and out of the chamber, and the number of pieces that can be vacuum-sealed in one operation is small.For example, it takes about 50 minutes to vacuum-seal 8 pieces of 10 pieces.

中でＴＩＧ溶接して封止された金属管とする。EXAMPLES The present invention will be explained below using examples. FIG. 1 is a diagram illustrating a sealed metal tube and its sealing method according to the present invention. In FIG. 1, a flanged metal member 9 made of stainless steel and having seven rungs 9' is welded to an opening 1' at the upper end of a metal pipe 1 made of stainless steel. After filling a chemical substance into a metal container (not shown) through a through hole 10 having a tapered part 10' with a diameter of 5.3 mm at the upper part, a container with an outer diameter of 5 mm is used for sealing. The metal member 11 is inserted. Thereafter, the flange part 9' is supported from below by a lower support part 12 which also serves as an electrode of the exhaust/spot welding device, and an electrode 15 is attached to the part 14 which serves as both an electrode and an exhaust part via an O-ring 13 from above. An exhaust pipe 16 is provided, and the lower surface of the electrode 15 is connected to the sealing metal member 1.
By placing the sealing metal member 11 close to the top surface of the sealing member 1, the sealing metal member 11 is prevented from falling out when the inside of the metal container is evacuated. Evacuation to create a vacuum inside the metal container is performed via the exhaust pipe 16, and then the sealing metal member 1 is removed by the electrode 15.
1 is pressed, spot welded to the flanged metal member 9, and vacuum-sealed. After vacuum-sealing in this manner, the upper support part 14 is removed, the welding nozzle of the TIG welding device is brought close to the flanged metal member 9, and the armpit is TIG-welded in the air to form a sealed metal tube.
