シールドアーク溶接用ワイヤに関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a flux-cored strand wire for welding, and in particular to a flux-cored strand wire that can be welded in the atmosphere without supplying arc encapsulation gas or solvent from the outside during welding. The present invention relates to a self-shielded arc welding wire.
フラックス入りワイヤはこれまで種々のものが提案され
、それをワイヤの断面形状で示すと第２図のようなもの
がある。Various types of flux-cored wires have been proposed so far, and the cross-sectional shape of the wire is shown in Fig. 2.

接金属の諸性性が最も優れている。According to a recent detailed study by Kihata et al., Figure 2 (
The double type flux-cored wire (Japanese Patent Publication No. 44-2336), which has a cross section as shown in j) and has an outer flux 4 and an inner flux 5, has a good surface area during welding and has the best properties of the weld metal. Are better.

。In particular, it enables welding in the atmosphere without externally supplying gas or solvent for arc encapsulation during welding. Nineteen facts have been recognized that are advantageous for flux-cored wires used in so-called non-encapsulated arc welding.

性を持たすことができ、高品質の溶接金属が得られるも
のである。Wires other than those shown in FIG. 2(j) are such that during welding, the core body 2 or 3 melts at a slower rate than the metal envelope 1, which impairs the protection of the molten metal during welding, and therefore the resulting weld Metal quality is low F. On the other hand, according to the double structure flux-cored wire shown in FIG. The inner flux storage chamber stores a powder made of an alloy material or a reducing material as a core 5, and the outer flux storage chamber stores a gas generating agent, a slag forming agent, etc. 4 that protects the weld metal during welding work. This allows for uniform melting over the entire cross section. Furthermore, as mentioned above, since the inner core is surrounded by outer flux in a concentric circle, the shielding effect of the protective gas decomposed by the outer flux is improved, eliminating the shadow of the atmosphere!
This provides high quality weld metal with high reliability in protecting the molten metal against air without the need for supplementary measures such as gases or fluxes.

当初の目的に反する結果に至ること、
など製造１−の難しさを有している。However, when manufacturing a wire with a cross-sectional shape as shown in Figure 2 (j), a) the shape of the forming roller is complex, the number of forming rollers is large, and high precision is required for each part of the manufacturing equipment. (Note) If the concentricity, which is a characteristic of this wire, is disrupted, it will cause deterioration of workability during welding and the occurrence of welding defects.
It has the difficulties of manufacturing 1-, such as leading to a result that goes against the original purpose.
従来から実体ワイヤやフラックスを内包した複合ワイヤ
を撚り合わせて一体化させたストランドワイヤが提案さ
れ、特開昭５２−１１７２５５等でも種々の技術が提案
されている。Strand wires in which solid wires and composite wires containing flux are twisted and integrated have been proposed in the past, and various techniques have also been proposed in Japanese Patent Application Laid-Open No. 117255/1983.
このようなストランドワイヤは素ワイヤの作り易さの点
で第２図（ｊ）のものに勝る。Such a strand wire is superior to the one shown in FIG. 2(j) in terms of ease of making a bare wire.
しかしながら、これまでの複合ワイヤを撚り合わせて一
体化したストランドワイヤは。However, conventional strand wires are made by twisting and integrating composite wires.
（１）アークの発生点を分散させること。(1) Dispersing the points where arcs occur.
（２）撚り合わせた消耗電極を形成している個々のワイ
ヤに開先側面への指向性をグーえること。(2) The individual wires forming the twisted consumable electrode can have directivity toward the side surface of the groove.
を目的とするものであった。その目的のために断面形状
が正多角形を形成しないもので、同心円状に形成しない
ため、ガス・シールドが不完全になり、別途シールガス
を使用せざるを得ない欠点を有している。The purpose was to For this purpose, the cross-sectional shape does not form a regular polygon and is not formed concentrically, resulting in an incomplete gas shield, which has the disadvantage that a separate sealing gas must be used.
本発明の主要な目的はストランドワイヤであって、前述
の第２図（ｊ）の断面を有するワイヤと同等の件部を得
ることができ、製造が容易なセルフシールドアーク溶接
用フラックス入すワイヤを提供することにある。The main object of the present invention is to provide a strand wire, which is a flux-cored wire for self-shielded arc welding that is easy to manufacture and has a similar cross section to the wire having the cross section shown in FIG. 2 (j). Our goal is to provide the following.
本発明は次の手段から成るものである。 The present invention consists of the following means.
■ 真直な中心素ワイヤとその外周に撚り合わせてこれ
と一体化した複数の外周素ワイヤとからなるストランド
ワイヤである。■ It is a strand wire consisting of a straight central wire and a plurality of outer peripheral wires that are twisted and integrated around the outer periphery of the straight central wire.
■ 真直な中心ワイヤは合金材料、還元材料から成るフ
ラックスを収納している。■ The straight central wire contains a flux consisting of alloying and reducing materials.
■ 外周素ワイヤはガス発生剤、スラグ生成剤フラック
スを収納している。■ The outer wire contains a gas generating agent and a slag generating agent flux.
第１図において真直な中心素ワイヤ６は合金材料、還元
材料からなるフラックス粉体を収容した複合ワイヤであ
り、その外周に撚り合わせた外周素ワイヤ７はガス発生
剤やスラグ生成剤からなるフラックス粉体を収容した複
合ワイヤである。In FIG. 1, the straight central wire 6 is a composite wire containing flux powder made of an alloy material or reducing material, and the outer wire 7 twisted around its outer periphery is a composite wire containing flux powder made of a gas generating agent or a slag forming agent. It is a composite wire containing powder.
本発明はそれらをストランドワイヤとして一体化してな
る溶接用フラックス入りストランドワイヤ８である。The present invention is a flux-cored strand wire 8 for welding made by integrating these as a strand wire.
このような構成により、本発明のワイヤは前述の第２図
（Ｄに示したワイヤにおける内包フラックス部５と第１
図の中心素ワイヤ６が対応し、同じく外包フラックス４
と第１図の外周素ワイヤ７とが対応することとなる。With such a configuration, the wire of the present invention has the inner flux part 5 and the first part in the wire shown in FIG.
The central wire 6 in the figure corresponds to the outer flux 4.
This corresponds to the outer wire 7 shown in FIG.
内包芯体を外包フラックスで同心円状に囲っているため
、前述の第２図（ｊ）と同様、保護ガスによるシールド
性が良くなるとともに、通電体である各素ワイヤを形成
するフープ材による外囲体がワイヤ断面全体にわたって
均斉に分布しているため、均斉に溶融することができ、
第２図（ｊ）のワイヤと同様の優れた効果が得られる。Since the inner core is concentrically surrounded by the outer flux, the shielding performance by the protective gas is improved as shown in Fig. 2 (j) above, and the outer core is protected by the hoop material forming each bare wire, which is a current-carrying body. Since the surrounding body is evenly distributed over the entire wire cross section, it can be melted uniformly,
Excellent effects similar to those of the wire shown in FIG. 2(j) can be obtained.

おいて外周素ワイヤの中６点を結ぶ線が正多角形をなさ
ない場合には各外周素ワイヤのねじりによるアークの偏
向を生じ、西宮の溶接には適さなくなる。Even if it is a strand wire in which a plurality of outer wires are twisted together around a straight central wire, adjacent wires do not touch each other, that is, six points among the outer wires in the cross section are If the connecting lines do not form a regular polygon, the arc will be deflected due to twisting of each outer wire, making it unsuitable for Nishinomiya welding.

ようになり。If the outer wires forming the periphery are in contact with the center wire and adjacent outer wires, and the line connecting the center points of the outer wires forms a regular polygon, then Equilateral triangle in figure 3, square in figure 4, figure 5
They look like the regular pentagon in the figure, the regular hexagon in Figure 6, and the regular octagon in Figure 7.
いずれもアークの偏向は生じないが、正三角形、正方形
および正五角形については中心素ワイヤが細くなり過ぎ
るために、中心に入れるべき合金材料、還元材料の訃が
少なくなり過ぎ、実用性に乏しいことが判明した。In either case, arc deflection does not occur, but in the case of equilateral triangles, squares, and regular pentagons, the central element wire becomes too thin, so the alloy material and reducing material that should be placed in the center are too small, making them impractical. There was found.
第６図〜第７図のように外周素ワイヤが６木以ヒ、つま
り正六角形以上のものについては良好な結果を得ること
ができた。As shown in FIGS. 6 and 7, good results were obtained when the outer wire had a diameter of 6 mm or more, that is, a regular hexagon or more.
