役目を達成するために有力な方法である。[Detailed Description of the Invention] When aluminum tubes are manufactured using aluminum tape as a starting material, relatively thin-walled, small-diameter, and long lengths can be manufactured at low cost. This is an effective method for moisture-proofing certain small-diameter electric wires and achieving a certain degree of mechanical protection.

ではない。 For this reason, the present inventors previously developed a method as shown in FIG. That is, the figure shows a manufacturing line for a metal tube containing a filament, and the filament 1 is fed out from a reel 2, and at the same time, an aluminum tape 3 is fed out from a reel 4 and advanced through a slitter 5. The two are then combined into an edge treatment roll,
A metal tube is loosely formed around the filament body 1 through a forming unit 6 consisting of a plate die and a forming die, and then the seam portion is welded with a welding torch 7.
Welding is carried out sequentially and sequentially through the first caterpillar traction device 10 and then the first diameter reducing device (die, plug).
8 and Triclean cleaning device 9, passes through a second caterpillar traction device 10', enters a second diameter reduction device (die) 8', Triclean cleaning device 9', and further passes through a third caterpillar traction device 10''. It is wound up on a take-up reel 11. Note that the number of diameter reducing devices, caterpillar traction devices, etc. is not limited to this.

ルが汚され爾後はピンホール修理が不可能であ
る。 However, in manufacturing metal tubes by rolling aluminum tape into a circular shape and welding the mating ends, it is extremely difficult to weld without pinholes using the current torch welding process, and the following shrinkage process is required. If the pinhole is not repaired before reaching the diameter stage (first diameter reduction), the pinhole will be contaminated with the lubricating oil for the plug used during diameter reduction, and the pinhole cannot be repaired thereafter.
従来は金属テープのつき合せ端部を熔接して金
属管を製造するにはこのピンホールの存在は致し
方ないものとして、製造中に修理することなくこ
れを肯定した程度の気密性の悪い用途にしか用い
られなかつた。 Conventionally, the presence of pinholes was considered unavoidable when manufacturing metal pipes by welding the mating ends of metal tapes, and was accepted without repair during manufacturing for applications with poor airtightness. It was only used.
しかしながら、吸湿により特性の低下を来すよ

田により密閉しなければならない。 However, when attempting to manufacture an aluminum tube containing a filament such as an electric wire whose characteristics deteriorate due to moisture absorption, it is necessary to seal the pinhole with solder.
本発明者らは種々検討の結果、第１図に示した
如き製造ラインを停止することなく、その進行中
にハンダ付けするには一般のアルミ半田やフラツ
クスは不適当で、下記の組成のものにして初めて
実現できることがわかつた。 As a result of various studies, the inventors of the present invention found that ordinary aluminum solder and flux were unsuitable for soldering while the production line was in progress without stopping the production line as shown in Figure 1, and the following composition was used. I realized that I could make it happen for the first time.
(a) アルミ半田：錫15〜25重量％、銀１〜５重量
％、残部鉛。(a) Aluminum solder: 15-25% by weight of tin, 1-5% by weight of silver, balance lead.
(b) フラツクス：硼素化亜鉛５〜20容量％、硼弗
化アンモニウム２〜５容量％、トリエタノール
アミン又はエチレングリコール65〜95容量％。(b) Flux: 5-20% by volume of zinc boronide, 2-5% by volume of ammonium borofluoride, 65-95% by volume of triethanolamine or ethylene glycol.
アルミニウム管の製造ラインを停止することな

で処理してピンホールを埋めなければならない
し、また半田によりその部分が盛り上るようにな
つてしまうと、アルミ管の縮径を円滑に変形なく
行なうことができないが、上記した以外の公知の
半田及びフラツクスではいづれも満足な成果が収
められなかつた。 In order to perform aluminum soldering without stopping the aluminum tube manufacturing line, the pinholes must be filled in an extremely short period of time, and if the solder swells up in that area, the aluminum Although it is not possible to reduce the diameter of the tube smoothly without deformation, none of the known solders and fluxes other than those mentioned above have been able to achieve satisfactory results.
本発明で使用する半田は、短時間で処理でき、
しかも半田が盛り上るような形態にはならない。
又本発明で用いるフラツクスについてもその流れ
がよく、半田は薄く伸ばすのに極めて有効であつ
た。 The solder used in the present invention can be processed in a short time,
Moreover, the solder does not swell up.
Furthermore, the flux used in the present invention had good flow and was extremely effective in spreading the solder thinly.
特にフラツクスについては金属の塩化物系は流
れが悪く、吸湿性であり、有機フラツクスのみで
は流れは良いが保持性が悪い等の欠点があるが、
本発明では硼酸系と有機フラツクスとを組合せた
フラツクスであつて、適当な流れ性と保持性とを
発揮し、しかも耐食性の強いと見られる弗素化合
物についてもトリクレン洗滌装置によりアルミニ
ウム管表面から除去されるので実害を生じないも
のである。 Regarding fluxes in particular, metal chloride-based fluxes have poor flow and are hygroscopic, while organic fluxes alone have drawbacks such as good flow but poor retention.
In the present invention, the flux is a combination of a boric acid type and an organic flux, and exhibits appropriate flowability and retention properties.Furthermore, fluorine compounds, which are considered to have strong corrosion resistance, are also removed from the surface of the aluminum pipe using a trichlene cleaning device. It does not cause any actual harm.
以上の通り本発明ではアルミニウムテープから
アルミ管を製造するタンデムラインを全く停止す

果がある。 As described above, the present invention has the effect of detecting pinholes between welding and the first diameter reduction and soldering the pinholes without stopping the tandem line for manufacturing aluminum pipes from aluminum tape. .
