ある。TECHNICAL FIELD The present invention relates to a solid wire for arc welding used when performing arc welding using a shielding gas, and particularly when excellent welding workability is required during welding. The present invention relates to a solid wire for gas shield arc welding used in.

る現象である。When a solid wire for arc welding is welded using a shield gas, droplets having a relatively large diameter are formed at the tip of the wire, and the droplets migrate to the base material due to particles or a short circuit. This is because when the droplets migrate, large particles of spatter are generated due to the effect of gas release from the wire and arc force accompanying the temperature rise, and arc state, arc length, arc concentration, droplet transfer state Is a phenomenon that is seen as deterioration of arc stability.

接用ソリッドワイヤは他のフラックスを用いる溶接材料
に比べアークが硬いとの苦情もある。There is a welding relationship between the generation of spatter and the arc state.If the droplet becomes large, large spatter easily occurs, and if the droplet becomes large, the repulsive force of the arc causes the droplet to shake violently at the tip of the wire. Welders dislike it as arc instability. Further, there is a complaint that the solid wire for gas shield arc welding has a harder arc than welding materials using other fluxes.

などの理由から多用されているのが現状である。However, the solid wire for gas shielded arc welding does not use flux as compared with arc welding that uses flux, such as welding with a coated arc welding rod or flux-cored wire, and the welding form is simple and the wire cost is low. At present, it is widely used because of the fact that continuous welding is possible for a long time.
従って、ガスシールドアーク溶接用ソリッドワイヤに
於いては冒頭に述べたいわゆる溶接作業性が現状技術に
よるものより優れていれば溶接者に一層好まれることに
なる。Therefore, in the case of the solid wire for gas shielded arc welding, if the so-called welding workability mentioned at the beginning is superior to that of the current state of the art, it will be more preferred by the welder.

も好ましいワイヤであるとは言えない。As one of these solutions, for example, JP-A-61-2427
There is a wire described in Japanese Patent Publication No. 85. This is an example in which the degree of adhesion of the lubricating oil on the surface of the wire is improved to improve the feedability of the wire during welding, and the workability of welding is improved in order to obtain a uniform arc state. However, in this invention, the lubricating oil increases the amount of diffusible hydrogen in the weld metal, and there is a concern that the crack resistance will deteriorate. Therefore, it cannot always be said that the lubricating oil is a preferable wire.

限定し、かつその組成の一部をワイヤ表面に濃縮させた
ものである。The gist of the present invention is C: 0.01 to 0.15%, Si: 0.50 to 1.60%, M
n: 1.00 to 2.40%, P: 0.030% or less, S: 0.004 to 0.030%, T
i: 0.05 to 0.35%, N: 0.010% or less, O: 0.030% or less, or Al: 0.30% or less, the balance being iron and other unavoidable impurities, and the wire surface is copper-plated and copper-plated. The content of at least one element of Si, Mn, S, Ti and O in the inner part of the circumference in the range of 15μ from the wire surface to the center of the wire is higher than the average content of each element of the wire. It is a characteristic solid wire for gas shielded arc welding. That is, the composition of the gas shielded arc welding solid wire of the present invention is such that the composition is properly selected and limited, and a part of the composition is concentrated on the wire surface.
次に本発明ワイヤの各成分の限定理由について述べ
る。Next, the reasons for limiting each component of the wire of the present invention will be described.
まずＣは、Ｃ量増加によってアーク長が短かくなり、
短絡回数も増加し、溶接作業性を向上させる傾向があ
る。しかし多量のＣ含有はスパッタの多発や靱性の低下
など耐割れ性の劣化を生じさせるため上限を0.15％とし
た。Ｃ含有を低く抑えると短絡移行性はやや低下傾向を
示すものの、スパッタ発生量は減少し、溶接後のスパッ
タ除去作業も容易になる。またアーク状態のソフト化、
短絡による急激なアーク変動の減少等の効果が有り、そ
の効果は0.01％以上で顕著に認められる。そのため下限
を0.01％とした。First, for C, the arc length becomes shorter due to the increase in the amount of C,
The number of short circuits also increases, tending to improve welding workability. However, a large amount of C content causes deterioration of crack resistance such as frequent occurrence of spatter and deterioration of toughness, so the upper limit was made 0.15%. If the C content is suppressed to a low level, the short-circuit transfer property tends to decrease slightly, but the amount of spatter generated decreases and the work of removing spatter after welding becomes easy. Also, softening the arc state,
There is an effect such as a rapid decrease in arc fluctuation due to a short circuit, and the effect is noticeable at 0.01% or more. Therefore, the lower limit was made 0.01%.
Siは主要な脱酸性元素として溶接金属の清浄度、靱性
を確保するために必須であり、0.50％以上含有すること
によりアークが安定し、健全な溶接金属が得られる。し
かし多量に含有しても短絡回数の増加によるスパッタ量
の増加や靱性の劣化等があり、上限を1.60％とした。Si is essential as a major deoxidizing element to secure the cleanliness and toughness of the weld metal, and by containing 0.50% or more, the arc is stable and a sound weld metal can be obtained. However, even if it is contained in a large amount, there is an increase in the amount of spatter and deterioration of toughness due to an increase in the number of short circuits, so the upper limit was made 1.60%.
Mnは脱散剤として寄与するとともに溶接金属の強度を
増加させる元素であり、1.00％以上の含有によりその効
果が得られる。しかし、多量に含有させるとスパッタ量
が増加するだけであり、上限を2.40％とした。Mn is an element that contributes as a desorbent and increases the strength of the weld metal, and its effect can be obtained by containing 1.00% or more. However, if a large amount is contained, the amount of spatter only increases, and the upper limit was set to 2.40%.
Ｐは不純物であり、Ｐの増加により靱性の低下をまね
くため少ないほど望ましく、0.030％を超えてはならな
い。P is an impurity, and it is desirable that it is as small as possible because it causes a decrease in toughness due to an increase in P, and it should not exceed 0.030%.
Ｓはスラグ量の減少、スパッタ量の低減に有効なばか
りでなく、ビード形状をも良好にする作用があり、その
効果は0.004％以上で認められる。0.030％超ではビード
形状改善の点からは効果が少なく、高温われ感受性が高
くなるため上限を0.030％とした。S is effective not only in reducing the amount of slag and sputtering, but also in improving the bead shape, and the effect is observed at 0.004% or more. If it exceeds 0.030%, the effect is small from the viewpoint of improving the bead shape and the high temperature susceptibility increases, so the upper limit was made 0.030%.
Tiは靱性を向上させるとともにスパッタ量の低減に有
効な元素である。Ti含有量0.05％まではスパッタ量の急
激な減少傾向を示すもののその後は飽和状態となる。そ
のため下限を0.05％とした。また、アーク状態も同様に
Ti含有量の増加にともない溶滴が微細化され急激に向上
するが、あまり多量に含有しても飽和傾向を示すため上
限を0.35％とした。Ti is an element effective in improving the toughness and reducing the amount of spatter. Up to a Ti content of 0.05%, the sputter amount shows a sharp decreasing tendency, but thereafter it becomes saturated. Therefore, the lower limit was made 0.05%. Also, the arc state is similar
The droplets become finer and sharply improve with an increase in the Ti content, but the upper limit was set to 0.35% because a saturation tendency tends to occur even if the Ti content is too large.
Ｎは低めの方がスパッタ量の減少、アーク状態の維
持、向上に効果があり、含有量が多い場合にはブローホ
ール発生の原因となるばかりでなく、アーク状態劣化の
傾向が認められるため上限を0.010％とした。Lower N is more effective in reducing the amount of spatter, maintaining and improving the arc state, and when the content is large, it not only causes blowholes but also tends to deteriorate the arc state. Was set to 0.010%.
Ｏは溶滴移行性を向上させスパッタ発生量の減少やビ
ード波目の均一性等に効果が有るが、多量のＯ含有は溶
接金属の靱性を著しく低下させるため上限を0.030％と
した。O improves the droplet transferability and is effective in reducing the amount of spatter generation and the uniformity of the bead wave. However, if a large amount of O is contained, the toughness of the weld metal is significantly reduced, so the upper limit was made 0.030%.
さらにAlは脱酸効果を狙いとし、溶接ビードの気孔発
生を防止するとともに結晶粒度を微細化させるために添
加することが出来るが、0.30％を超えるとメタルが過脱
酸状態となり、溶接金属が著しく硬化するため、上限を
0.30％とした。Furthermore, Al aims at the deoxidizing effect and can be added to prevent the generation of pores in the welding bead and to refine the grain size, but if it exceeds 0.30%, the metal becomes overdeoxidized and the weld metal is Because it hardens significantly, the upper limit is
0.30%.

14%, Ti: 0.25%, N: 0.0068%, O: 0.0080%] as a basic component, and at least one element of Si, Mn, S, Ti and O are concentrated in various widths from the surface of the wire did. In the wire trial production, after melting and forging, an original wire hot-rolled to a wire diameter of 5.5 mmφ was cold drawn to 1.2φ and manufactured. During the wire drawing, annealing was performed at a temperature higher than about 700 ° C, and for rust prevention and the like, copper plating was applied in the same manner as the conventional solid wire for gas shield arc welding, and the test was performed.

As shown in the figure, from the wire surface excluding copper plating to the inner part of the circumference in the range of 15μ in the wire center direction, Si, Mn, S,
The wire in which Ti and O were enriched in excess of the average content of each element of the wire showed very good welding workability.

となって溶接作業性が格段と向上する。According to the wire of the present invention in which a part of the wire composition is concentrated on the wire surface in this manner, the welding arc is changed from the conventional hard state to the soft state, and the size of droplets generated at the wire tip is reduced, The transfer of these droplets to the base material becomes smooth, and the welding workability is remarkably improved.
