この発明はステンレス鋼で形成された温水タンクのよう
な水蜜容器の接合方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Applications] This invention relates to a method of joining a honey container, such as a hot water tank, made of stainless steel.
第２図は従来のステンレス鋼を用いた電気渇水器の温水
タンクを示す。すなわち、この温水タンクは円筒胴部１
と、この胴部の両端開口を水密状態に閉塞する一対の端
蓋２，３とからなり、胴部１内に水を加熱する電気ヒー
ターを内設するとともに端Ｍ２，３に給水管４と給湯管
５をそれぞれ接続している。そして、第３図に示すよう
に一対の端蓋２，３は胴部１の両端開口の内側に所定幅
の接合５（ｓ）を確保するよう嵌合され、かつ胴部１の
端面において溶接（Ａ）固定されている。FIG. 2 shows a hot water tank of an electric water heater using conventional stainless steel. That is, this hot water tank has a cylindrical body 1
and a pair of end covers 2 and 3 that close the openings at both ends of the body in a watertight state, and an electric heater for heating water is installed inside the body 1, and a water supply pipe 4 is connected to the ends M2 and 3. The hot water supply pipes 5 are connected to each other. As shown in FIG. 3, the pair of end covers 2 and 3 are fitted together to ensure a joint 5(s) of a predetermined width inside the openings at both ends of the body 1, and welded at the end faces of the body 1. (A) Fixed.
上記のような従来の渇水タンクでは、胴部１と各端蓋２
，３との接合面の隙間部分に腐食を発生させていたが、
特に胴部１の端面にて溶接したような場合、水中に没す
る接合面が広いため、隙間腐食の発生する割合が高くて
胴部の端面部を溶接するための別途添加剤を必要とする
問題点があった。In the conventional drought tank as described above, the body part 1 and each end cap 2
Corrosion occurred in the gap between the joint surfaces with , 3,
In particular, when welding is performed at the end face of the body part 1, the joint surface submerged in water is wide, so crevice corrosion occurs at a high rate, and a separate additive is required for welding the end face of the body part. There was a problem.
この発明は、かかる問題点を解決するためになされたも
ので、隙間腐食の発生を極力抑えて長寿命とした水密容
器の接合方法を得ることを目的とする。The present invention was made to solve these problems, and aims to provide a method for joining watertight containers that minimizes the occurrence of crevice corrosion and has a long service life.
（問題を解決するための手段〕
この発明に係る水密容器の接合方法は、胴部と端蓋との
接合面の中央部にて胴部および＃蓋それ自体を直接溶か
すことにより接合固定したものである。(Means for Solving the Problem) A method for joining a watertight container according to the present invention is a method in which the body and the end cap are joined and fixed by directly melting the body and the lid at the center of the joint surface between the body and the end cap. It is.
この発明においては、胴部と端蓋との接合面の中央部に
溶接部が位置するから、水中に没する隙間部分面梢が半
減し、腐食の発生を抑えることができる。In this invention, since the welded portion is located at the center of the joint surface between the body and the end cap, the surface area of the gap submerged in water is halved, and corrosion can be suppressed.
以下、この発明の一実施例を図について説明する。すな
わち、第１図に示すように、ステンレス鋼からなる胴部
１と麹蓋２との嵌合部における両者の接合面の中央部を
例えばプラズマ溶接によって、胴部１から端蓋２に至る
までステンレス鋼自体を溶かし込むことにより溶接（Ａ
）固定している従って、水中に没する胴部１と端蓋２，
３との接合面（Ｃ）は半減となり、それ故かかる接合面
の隙間での腐食の発生を減することができる。An embodiment of the present invention will be described below with reference to the drawings. That is, as shown in FIG. 1, the central part of the joint surface between the body 1 made of stainless steel and the koji lid 2 is welded by plasma welding from the body 1 to the end lid 2. Welding by melting the stainless steel itself (A
) The body part 1 and the end cap 2 which are fixed and therefore submerged in water,
The joint surface (C) with No. 3 is reduced by half, and therefore the occurrence of corrosion in the gap between the joint surfaces can be reduced.
以とのように、この発明によれば、隙間腐食の発生する
要因面積を減することが出来て、長寿命の製品が得られ
ろものであり５．又、溶接時の添加剤も不要となる効果
がある。As described above, according to the present invention, the area that causes crevice corrosion can be reduced, and a product with a long life can be obtained.5. Further, there is an effect that additives are not required during welding.
