A first compressor container member 1 and a second compressor container member 2 are brazed with their respective cylindrical ends overlapped with each other. Since the two cylindrical ends are brazed together in this manner, the first
Of the first compressor container member 1 has a smaller inner diameter than the second compressor container member 2, and the outer surface of the first compressor container member 1 is shaved at the portion where the cylindrical end portions of both are superposed. Is made small so that its outer diameter is approximately equal to the inner diameter of the second compressor container member 2. When the first compressor container member 1 and the second compressor container member 2 are brazed, various compressor functional parts, which are not assembled, are assembled in advance in a predetermined structure, which is not shown. In the housed state, the inner surface of the second compressor container member 2 is superposed and fitted on the cut outer surface of the first compressor container member 1, and the brazing material is supplied over the entire circumference of the fitted portion. Apply heat and braze. However,
In such a conventional compressor container and its manufacturing method, since the brazing speed is slow, heat may be trapped inside the compressor container, which may adversely affect the compressor functional parts housed therein. There has been a problem that a brazing material made of a material suitable for the material forming the container is required in a considerable amount. Also, the first
Since the inner diameters of the compressor container member 1 and the second compressor container member 2 are different and the thickness of the first compressor container member 1 at the fitting portion is thin, there is a problem in mechanical strength. Further, there are drawbacks that flux, gas, etc. are generated during the brazing work, which makes the working environment poor and requires a post-treatment, which requires a considerable amount of time before the final work.

ことにより，同様に溶接することができる。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1 and 2. The first compressor container member 1 and the second compressor container member 2 have substantially the same inner diameter and outer diameter. Is designed to be. The respective cylindrical ends 1A and 2A of the first compressor container member 1 and the second compressor container member 2 have been ground in advance and are thinner than the respective cylindrical parts 1B and 2B. That is, the respective cylindrical end portions 1A and 2A are tapered. Both sides are cut away in the drawing,
Only the inside may be cut. In integrating these, the second compressor container member 2 is used as usual.
First, the first compressor container member 1 is set in the lower welding electrode 4 of the resistance welding machine in a state in which various compressor functional parts assembled in a predetermined configuration are stored in advance.
Is set on the upper welding electrode 3. These upper and lower welding electrodes 3 and 4 are each divided into two or more parts so that they can be expanded or narrowed in the radial direction.
The first and second compressor container members 1 and 2 are set with the upper and lower welding electrodes 3 and 4 spread out,
After that, it is narrowed and gripped with a predetermined force. In that state, the upper welding electrode 3 descends,
Butt the cylindrical end 1A of the compressor container member 1 with the cylindrical end 2A of the second compressor container member 2,
It pressurizes so that a pressing force may be applied to those cylindrical ends almost uniformly. This pressure is several tons or more for large ones. As described above, when the charging energy stored in the capacitor (not shown) is discharged between the upper and lower welding electrodes 3 and 4 in the state where the pressure is applied to the first compressor container member 1 as described above, the first butted parts A large electric current concentrates instantly on the cylindrical end portion 1A of the first compressor container member 1 and the cylindrical end portion 2A of the second compressor container member 2, and the heat generated at that time causes the cylindrical end portion 1A to 2A is melted and welded firmly. During this welding, the cylindrical end portions 1A of the first and second compressor container members 1,
The cylindrical end portion 2A acts as a projection and enables good welding with a relatively small welding current. In addition, in this embodiment, the welding AC power is supplied from the commercial AC power source even if the capacitor is not charged with energy by preliminarily increasing the welding time or preparing equipment having a large current capacity. Through (not shown)
Similarly, welding can be performed by passing an electric current through the cylindrical end portion 1A of the compressor container member 1 and the cylindrical end portion 2A of the second compressor container member 2.

幅に短縮でき，実用上の効果は極めて大きい。As described above, according to the present invention, since the welding speed is remarkably higher than that of the conventional brazing method, the compressor functional parts housed therein are not adversely affected, and Work efficiency is significantly improved compared to the past. Since the inner and outer diameters of the first compressor container member 1 and the second compressor container member 2 are the same, it is only necessary to butt the first and second compressor container members 1 and 2 together during welding, and automation is easy. Is. In addition, since no flux, gas, etc. are generated during welding work, it does not deteriorate the work environment and does not require post-treatment as in the past, so the time to final integration work can be greatly shortened. ， The practical effect is extremely large.
