This relates to gold welding wire.
（従来の技術及び解決しようとする課題）超電導ロータ
材は構造材料として高強度・非磁性鋼が要求され、引張
強さ１００ ｋｇ／ｍｍ”以上、０．２％耐力が８０
ｋｇ ／ ｍｍ”以上が必要であり、これにはインコネ
ル７１８、Ａ２８６等が考えられるが、Ａ２８６は耐力
が低いため、インコネル７１８が使用されることが多い
。しかし、インコネル７１８を溶接構造材として用いた
場合、溶接時に割れを発生するという問題がある。(Prior art and problems to be solved) Superconducting rotor materials require high-strength, non-magnetic steel as a structural material, with a tensile strength of 100 kg/mm or more and a 0.2% yield strength of 80
kg/mm" or more is required, and Inconel 718, A286, etc. can be considered for this, but since A286 has low yield strength, Inconel 718 is often used. However, Inconel 718 is not used as a welded structural material. If it is, there is a problem that cracks will occur during welding.
すなわち、インコネル系材料は、引張強さや耐力が高い
という特性があるが、割れ易いのが欠点である。That is, Inconel materials have the characteristics of high tensile strength and yield strength, but have the disadvantage of being easily broken.

The gist of the present invention is a welding wire made of a nickel-based alloy characterized by having a composition containing 50 to 2.00% and 1% or less of B:O, OO.
以下に本発明を詳述する。The present invention will be explained in detail below.
（作用）
本発明における化学成分の限定理由は以下のとおりであ
る。(Function) The reasons for limiting the chemical components in the present invention are as follows.
Ｃ：０．０２５％以下
Ｃは引張強さ及び０．２％耐力を上げる作用があるが、
一方では溶接割れを助長する元素であるため、Ｃ量は０
．０２５％以下に限定する。C: 0.025% or less C has the effect of increasing tensile strength and 0.2% proof stress, but
On the other hand, since it is an element that promotes weld cracking, the amount of C is 0.
．． Limited to 0.025% or less.
Ｓｉ：０．３０％以下
Ｓｉは引張強さや０．２％耐力にはあまり影響を及ぼさ
ないが、溶接割れに大きな影響を与える。Si: 0.30% or less Si does not have much effect on tensile strength or 0.2% proof stress, but it has a large effect on weld cracking.
第３図はワイヤ（図中の恥は第３表の恥に同じ）中のＳ
ｉ量を変えて溶接割れの影響を調べたものである。同図

接割れが発生するようになる。したがって、Ｓｉ量は０
．３０％以下に限定する。Figure 3 shows S in the wire (Shame in the figure is the same as Shame in Table 3).
The influence of weld cracking was investigated by changing the amount of i. As is clear from the figure, when the Si content exceeds 0.30%, weld cracking begins to occur. Therefore, the amount of Si is 0
．． Limited to 30% or less.
Ｍｎ：５．５％以下。Mn: 5.5% or less.
Ｍｎはビード表面に発生するスラグに影響を与え、５．
５％を超えるとビード表面にスラグが多量に発生するよ
うになり、それに伴ってビードのなじみが悪くなり、ビ
ード幅が安定しなくなる。Mn affects the slag generated on the bead surface, 5.
If it exceeds 5%, a large amount of slag will be generated on the bead surface, resulting in poor bead conformability and unstable bead width.
したがって、Ｍｎ量は５．５％以下に限定する。Therefore, the amount of Mn is limited to 5.5% or less.
Ｐ：０．０１０％以下、
Ｐは溶接割れを助長する元素であり、極力低い方が好ま
しいが、Ｓに比較し、その効果が低いので、０．０１０
％以下に限定する。P: 0.010% or less, P is an element that promotes weld cracking and is preferably as low as possible, but its effect is lower than S, so 0.010%
% or less.
Ｓ：Ｏ，Ｏｏｓ％
Ｓは、Ｐと同様１粒界に析出し、溶接割れの原因となり
、その程度はＰより大きいため、本発明では０．００６
％以下に限定する。S: O, Oos% S, like P, precipitates at one grain boundary and causes weld cracking, and the degree of this is greater than P, so in the present invention, 0.006
% or less.
Ｎｉ：４５．０〜５５．０％
本ワイヤは、極低温で使用する超電導ロータ材としての
インコネル系材料の溶接用ワイヤの開発を主目的として
いるため、低温靭性の良いニッケル系合金にするため、
Ｎｉ量を４５．０〜５５．０％の範囲に限定する。Ni: 45.0 to 55.0% The main purpose of this wire is to develop a wire for welding Inconel-based materials as superconducting rotor materials used at extremely low temperatures, so we created a nickel-based alloy with good low-temperature toughness. ,
The amount of Ni is limited to a range of 45.0 to 55.0%.
Ｃｒ：１０．０〜３０．０％
Ｃｒは１０．０％未満では一般に耐食性が悪くなるため
、それ以上の添加が必要である。しかし、３０．０％を
超えると熱間加工性が悪くなり、溶接ワイヤの製造が困
難になるので、Ｃｒ量は１０゜０〜３０．０％の範囲と
する。Cr: 10.0 to 30.0% If Cr is less than 10.0%, corrosion resistance generally deteriorates, so it is necessary to add more than that. However, if it exceeds 30.0%, hot workability deteriorates and manufacturing of welding wire becomes difficult, so the Cr content is set in the range of 10°0 to 30.0%.
Ｍｏ：３．４〜６．０％
本威分系において、特にＭｏを３．４以上、６゜０％以
下に規制することにより、溶接割れを抑制する効果を有
することが明らかとなったため、Ｍｏ量を３．４〜６．
０％の範囲とする。Mo: 3.4-6.0% It has been found that regulating Mo to 3.4% or more and 6°0% or less has the effect of suppressing weld cracking in this system. The amount of Mo is 3.4 to 6.
The range is 0%.
Ｎｂ： ２ 、 ０〜４．５％
Ｎｂは引張強さ及び０．２％耐力の向上に効果を持ち、
添加量をますと引張強さ及び０．２％耐力が増加するが
、同時に溶接割れが発生し易くなる。Nb: 2, 0-4.5% Nb has the effect of improving tensile strength and 0.2% proof stress,
If the addition amount is increased, the tensile strength and 0.2% proof stress will increase, but at the same time, weld cracking will be more likely to occur.
第４図はワイヤ（＠中の恥は第３表の恥に同じ）中のＮ
ｂ量を変えて溶接割れの影響を調べたものである。同図
より明らかなように、Ｎｂ量が４．５％を超えると溶接
割れを発生するようになる。したがって９強度を確保し
つつ溶接割れを防止するために、Ｎｂ量は２．０〜４．
５％の範囲とする。Figure 4 shows the N in the wire (the shame in @ is the same as the shame in Table 3).
The influence of weld cracking was investigated by changing the amount of b. As is clear from the figure, when the amount of Nb exceeds 4.5%, weld cracking begins to occur. Therefore, in order to prevent weld cracking while ensuring 9 strength, the amount of Nb should be 2.0 to 4.
The range shall be 5%.
Ｔｉ：１．５０〜２．００％
溶接割れを抑制するためにＮｂ量を４．５％以下に抑え

図中の恥は第３表の尚に同じ）中のＴｉｆｉを変えて溶
接割れの影響を調べたものである。Ti: 1.50-2.00% If the Nb content is suppressed to 4.5% or less to suppress weld cracking, the tensile strength and 0.2% yield strength will be insufficient compared to the standard values, so the tensile strength It is necessary to add an element that increases the strength and 0.2% proof stress and does not cause weld cracking. As shown in FIG. 5, Tj is an element that meets this purpose, and for this purpose it has been found that the optimum Ti content is in the range of 1.50 to 2.00%. In addition, Fig. 5 shows the wire (
The values in the figure are the same as those in Table 3), and the effect of weld cracking was investigated by changing Tifi.
Ｂ：Ｑ、ＱＯ１％以下。B: Q, QO 1% or less.
Ｂは溶接割れに悪影響をもたらす元素であるため、極力
下げる必要がある元素であり、本発明ではＢ量を０．０
０１％以下に限定する。Since B is an element that has a negative effect on weld cracking, it is an element that needs to be reduced as much as possible. In the present invention, the amount of B is set to 0.0.
Limited to 0.1% or less.
なお、上記成分以外は、不純物であるが、不純物量は可
及的に少ないことが望ましい。Note that components other than the above-mentioned components are impurities, but it is desirable that the amount of impurities be as small as possible.
上記化学成分を有するワイヤを使用すると溶接割れが発
生しないのは、これらの成分が適正にバランスされてい
るためと考えられる。すなわち、本発明者が溶接割れ部
を調べたところ、第６図の写真に示すように、溶接割れ
部は粒界部であり。The reason why weld cracking does not occur when a wire having the above chemical components is used is thought to be because these components are properly balanced. That is, when the present inventor investigated the weld crack, as shown in the photograph of FIG. 6, the weld crack was found to be a grain boundary region.
粒界部には偏析が起こっており、割れ先端部を線分析し
た結果、Ｎｂ、Ｔｉ、Ｍｏ、Ｓ、Ｐ、Ｓｉ、Ｃ。Segregation occurs at grain boundaries, and line analysis of the crack tip reveals Nb, Ti, Mo, S, P, Si, and C.
Ｂ等が存在していることがわかった。したがって、これ

く調整することにより、初期の効果が得られるものと考
えられる。It was found that B etc. exist. Therefore, it is considered that initial effects can be obtained by controlling these components and adjusting other components such as Ni in a well-balanced manner.
なお、溶接対象は主にインコネル系材利用であり、その
組成は何ら制限されるものではない。また溶接条件も適
宜選定できる。It should be noted that the objects to be welded are mainly Inconel-based materials, and the composition thereof is not limited in any way. Furthermore, welding conditions can be selected as appropriate.
