大きく形成されている。A method for manufacturing a pressure vessel according to an embodiment of the present invention will be explained based on the drawings. As shown in FIG. 1, a cylindrical housing member 6 having openings at both ends is set on a jig 5, and lid members 7 and 8 are inserted into both openings of the housing member 6.
are brought into contact with the electrodes 9.10. As shown in FIG. 2, the lid member 7.8 includes a disk portion 11, an outwardly opened tapered slope portion 12 formed on the outer periphery of the disk portion 11, and a tapered slope portion 12 connected to the slope portion 12. The outer diameter d2 of the small diameter part of the tapered inclined part 12 is formed to be equal to or less than the inner diameter 4 of the opening of the housing member 6, and the outer diameter of the large diameter part is formed of seven annular rung parts 13. The inner diameter d of the opening is made larger.
11aは流体導入管あるいは導出管を接続するための孔
である。Reference numeral 11a is a hole for connecting a fluid inlet pipe or a fluid outlet pipe.
したがって、ハウジング部材6の1市口部には前記蓋部
材7.8のテーパ状傾斜部】2が当接する。Therefore, the tapered inclined portion 2 of the lid member 7.8 comes into contact with the opening 1 of the housing member 6.
次に、蓋部材を押圧しながら電極9,10に通電させて
ハウジング部材6と蓋部材7,8を同時に抵抗溶接する
。第3図はこのようにして製造された圧力容器140i
〜1面図である。前記のようにして製造された圧力容器

幅が増大する。したがって、溶は込み部15の幅(接合
幅)がハウジング部材6の板厚よりも大きくなり高い接
合強度が得られる。また、7ラング部13は、前記溶接
時の位置決め用ストッパとして作用するものであるが、
溶接時の通電時間を若干長くすることにより第5図に示
すように、この7ラング部13も溶は込まして接合幅を
長くし、接合強度をさらに高くすることもできる。Next, the housing member 6 and the lid members 7, 8 are simultaneously resistance welded by energizing the electrodes 9, 10 while pressing the lid member. FIG. 3 shows a pressure vessel 140i manufactured in this way.
~This is a front view. As shown in FIG. 4, in the pressure vessel 14 manufactured as described above, the opening of the housing member 6 at each joint portion is slightly deformed outward due to the heating caused by the electricity supply and the pressing force by the electricity 9!9.10, and the lid is closed. Member 7.80 abutment width increases. Therefore, the width of the melt-in part 15 (joint width) is larger than the thickness of the housing member 6, and high joint strength can be obtained. Furthermore, the seven rungs 13 act as positioning stoppers during welding, but
By slightly lengthening the current application time during welding, as shown in FIG. 5, the seven rung portions 13 can also be penetrated to increase the joint width and further increase the joint strength.
さらに、抵抗溶接は溶接に要する時間が短く自動化も容
易であり製造性を向上することができ、材料として耐圧
性の高い鉄系の材料を使用でき耐圧強度を低下させるこ
とはない。Furthermore, resistance welding requires less time for welding and can be easily automated, improving manufacturability, and allows the use of iron-based materials with high pressure resistance, without reducing pressure resistance.
また、前記溶接にはフィラー材が不要であるためスパッ
タの発生が少なく、シかも、絶えずテーパ部で圧接しな
がら溶接するので隙間の発生はなく、仮りにスパッタが
発生したとしても、ハウジング部材6内への侵入を防止
することができる。In addition, since filler material is not required for the welding, there is less spatter, and since the welding is performed while being constantly pressed at the tapered part, there is no gap, and even if spatter occurs, the housing member 6 It is possible to prevent intrusion into the interior.
さらに、溶接時の加熱時間が短いので酸化スケールの発
生も少なくすることができる。Furthermore, since the heating time during welding is short, the generation of oxide scale can be reduced.

ウジング部材にも適用可能であることは勿論である。Further, although the lid members 7 and 8 and the electrodes 9 and 10 are brought into contact with the opening of the housing member 6 at the same time, the lid members 7 and 8 are
8 may be brought into contact with the opening of the housing member 6. Furthermore, it goes without saying that the present invention is also applicable to housing members having only one opening.
