Conventional composite wires for electrogas arc welding cannot ensure the toughness of the weld metal itself and the reheated part of the heat-affected zone, and are not applicable despite their excellent welding efficiency. Therefore, it has been considered difficult to apply it to multi-layer stacking or X-groove joints at low temperatures.

物のみとすることの３点が有効であるとの知見が得られ
た。The present inventor has been involved in research on electrogas arc welding for many years, and as a result of repeated research and manufacturing of wire prototypes over the years, he has found that in order to improve the low-temperature toughness of the weld metal and the reheated part of the heat-affected zone. , M present in the weld metal
O has the effect of coarsening the microstructure during reheating, so it should be avoided as much as possible; Ni, which does not coarsen even when reheated and makes the microstructure finer and more uniform, should be added; As the amount of oxygen increases, the microstructure becomes coarser, so three effective methods are to remove all oxides added as slag-forming agents that serve as oxygen sources, and to use only metal fluoride as the slag-forming agent. The following findings were obtained.
そこで、３点の知見を組合せ、充填フラックス中から従

従来ワイヤには見られなかった溶接金属および熱影響部

き、本発明を構成するにに至った。Therefore, by combining three points of knowledge, we removed the conventionally added Mo from the filling flux, added Ni, and used only metal fluoride as the slag forming agent, and repeated the experiment.
A composite wire with excellent low-temperature toughness of the weld metal and the reheated part of the heat-affected zone, which has not been seen in conventional wires, can be obtained, and the present invention has been completed.
以下、充填フラックスの成分組成について説明する。The composition of the filling flux will be explained below.
金属弗化物はアーク安定性を高めると共に脱水素作用に

ラグの流動性が過大となり、スラグ被包性が悪く、ビー
ド形状が悪化する。Metal fluorides have the effect of increasing arc stability and improving the low-temperature toughness of weld metal through dehydrogenation. These effects can be effectively exhibited by adding 0.7% or more of metal fluoride. However, if it exceeds 1.5%, the fluidity of the slag becomes excessive, the slag envelopment is poor, and the bead shape deteriorates.
従って０．７〜１．５％の範囲とする。金属弗化物とし
ては、Ｎａ、 Ｋ、 Ｌｉ＋ Ｍｇ、 Ｃａ等のアル
カリ金属およびアルカリ土類金属の弗化物が一般的に用
いられる。Therefore, it should be in the range of 0.7 to 1.5%. As the metal fluoride, fluorides of alkali metals and alkaline earth metals such as Na, K, Li+Mg, and Ca are generally used.
Ｍｎはスラグの流動性を調整し、ビード形状を改善する
と共に溶接金属の脱酸を促進し、かつ溶接継手に適した
強度を与えるために添加される。Mn is added to adjust the fluidity of the slag, improve the bead shape, promote deoxidation of the weld metal, and provide suitable strength to the welded joint.
０．７％未満では、必要な強度が得られない。一方１．
５％を超えると強度は向上するが逆に靭性を劣化させる
。従ってＭｎの添加量は０．７〜１．５％とする。なお
、Ｍｎは単体で用いられる他、Ｆｅ−Ｍｎ、Ｆｅ５１−
Ｍｎ等の鉄合金の形態でも使用できる。If it is less than 0.7%, the required strength cannot be obtained. On the other hand 1.
If it exceeds 5%, the strength will improve, but the toughness will deteriorate. Therefore, the amount of Mn added is set to 0.7 to 1.5%. In addition, Mn is used alone, as well as in Fe-Mn, Fe51-
It can also be used in the form of an iron alloy such as Mn.
Ｓｉは有効な脱酸剤であると共に、ビード外観、および
溶接作業性を改善するが、０．１５％未満では、これら
の効果が得られない。しかし、０．５％を超えると溶接
金属中のＳｉが過剰となって靭性を劣化させるので好ま
しくない。従ってＳｉは０．１５〜０．５％とする。な
お、Ｓｉは単体あるいは、ＦｅＳｉ、 ＦｅＦｅ−５ｉ
−等の鉄合金の形態でも使用できる。Si is an effective deoxidizing agent and improves bead appearance and welding workability, but if it is less than 0.15%, these effects cannot be obtained. However, if it exceeds 0.5%, Si in the weld metal becomes excessive and deteriorates toughness, which is not preferable. Therefore, Si should be 0.15 to 0.5%. In addition, Si is a simple substance, FeSi, FeFe-5i
It can also be used in the form of iron alloys such as -.
Ｍｇは強力な脱酸剤である。特に溶接金属中の酸素量を
低減するのには、最良である。添加量が０、１％未満で
はその効果が十分得られず、一方、０．６％を超えると
溶接作業性が悪化して、スパッタ発生量が多くなると共
に低温靭性も劣化させる。Mg is a strong deoxidizer. In particular, it is best for reducing the amount of oxygen in weld metal. If the addition amount is less than 0.1%, the effect will not be sufficiently obtained, while if it exceeds 0.6%, welding workability will deteriorate, the amount of spatter will increase, and low-temperature toughness will also deteriorate.
従ってＭｇの適正範囲は０．１〜０．６％とする。Ｍｇ
は単体もしくは、Ｎｉ −Ｍｇ、 Ｃａ−Ｍｇ、 Ｆｅ
−Ｍｇ＋Ｆｅ −５１Ｍｇ等のＭｇ合金の形態で添加し
てもよい。Therefore, the appropriate range of Mg is 0.1 to 0.6%. Mg
is alone or Ni-Mg, Ca-Mg, Fe
-Mg+Fe It may be added in the form of an Mg alloy such as -51Mg.
ＴｉはＴｉ酸化物を形成し、溶接金属のミクロ組織を微
細化し、低温靭性改善に有効であるが、０．０５％未満
ではこの効果が望めないので下限を０．０５％とする。Ti forms Ti oxide, refines the microstructure of the weld metal, and is effective in improving low-temperature toughness, but if it is less than 0.05%, this effect cannot be expected, so the lower limit is set at 0.05%.
また０、２５％を超えると低温靭性を著しく損なうので
、上限を０．２５％とする。Ｔｉは金属Ｔｉの他にＦｅ
−Ｔｉ等の合金として添加してもよい。Moreover, if it exceeds 0.25%, low-temperature toughness will be significantly impaired, so the upper limit is set to 0.25%. Ti is Fe in addition to metal Ti.
-It may be added as an alloy such as Ti.

すぎると溶接金属の高温割れが発生し易くなるので、上
限を０．０２％とする。Ｂ源としてはＦｅ−Ｂ、 ア
トマイズＢ等の合金として添加することもできる。Since B is a strong deoxidizing carbide-forming element, adding it to the wire refines the crystal grains in the weld metal. It also has the effect of increasing the hardenability of the weld metal, and in order to obtain such an effect, a minimum of 0. OO2
% of B is required, and if it is less than that, there is no effect (and if it is too much, hot cracking of the weld metal is likely to occur, so the upper limit is set to 0.02%. As a B source, Fe-B, It can also be added as an alloy such as Atomized B.
Ｎｉは溶接金属の靭性を上昇させるのに有効であり、特
に再加熱しても靭性が低下しない利点を有するが、１．
５％未満では効果がなく、また４、５％超であると溶接
金属の高温割れを起こすので、下限を１．５％とし、上
限を４．５％とする。Ni is effective in increasing the toughness of weld metal, and has the advantage that the toughness does not deteriorate even after reheating.
If it is less than 5%, there will be no effect, and if it exceeds 4.5%, hot cracking will occur in the weld metal, so the lower limit is set to 1.5% and the upper limit is set to 4.5%.
八！の添加は、ＴｉおよびＢの効果を助長する作用があ
るが、Ｏ，ＯＯ５％未満では効果がなく、逆に０．２５
％超では溶接金属を脆化させ靭性を低下させる。従って
、下限をＯ，ＯＯ５％とし、上限を０．２５％とする。Eight! The addition of O has the effect of promoting the effects of Ti and B, but it has no effect when O and OO are less than 5%, and on the contrary, when O and O are less than 5%,
If it exceeds %, the weld metal becomes brittle and its toughness decreases. Therefore, the lower limit is set to 5% O,OO, and the upper limit is set to 0.25%.
尚、Ａｌの添加方法としては単体もしくはＡｌ −Ｍｇ
、 Ｆｅ−Ａｌ等の合金の形で添加することができる。In addition, as for the addition method of Al, Al alone or Al-Mg
, Fe-Al, etc. can be added in the form of an alloy.
また、フラックスの充填率は特に限定されないが、伸線
性を考慮してワイヤ全重量に対して２０〜３０％の範囲
が最も適当である。Further, the filling rate of flux is not particularly limited, but in consideration of wire drawability, a range of 20 to 30% based on the total weight of the wire is most appropriate.

In the case of small diameter wires below, a relatively simple cylindrical wire is generally used, and in the case of large diameter wires of approximately 2.4 to 3.2++ unφ, wires with a structure in which the sheath material is folded in a complicated manner are generally used. . Furthermore, it is also effective to perform a plating treatment such as Cu on the surface of the seamless wire.
