り、その他自動車車体にも多く使用される傾向にある。[Prior Art] As a steel material which has been subjected to rust prevention treatment and has excellent corrosion resistance, for example, there is a galvanized steel plate. Galvanized steel sheet is a hot-rolled or cold-rolled steel sheet whose surface is galvanized, and its main use is in the field of thin sheets, building materials such as roof panels, gasoline cans, washing machine parts, etc. In addition, there is a tendency to be widely used for other automobile bodies.

して残存し、ピットやブローホール等の欠陥を多発す
る。When welding galvanized steel, zinc with a boiling point (906 ° C) lower than the melting point of iron from the steel surface penetrates into the drip or molten pool during welding, causing the vapor to boil and entrain the atmosphere, causing the weld metal to solidify. In the process, it does not float up and remains as bubbles, causing many defects such as pits and blowholes.
特に薄板の溶接に最も一般的に適用されているソリッ
ドワイヤを用いるガスシールド溶接法では亜鉛の影響を
顕著に受け易い。In particular, the gas shield welding method using a solid wire most commonly applied to welding of a thin plate is remarkably susceptible to zinc.

ット・ブローホールなどの欠陥が発生し易い。Generally, in gas shielded arc welding, the welding speed is
If it exceeds 1 m / min, the gas shielding property is reduced, and air is entrained in the welding atmosphere. As a result, a large amount of nitrogen gas is absorbed, and defects such as pits and blowholes are easily generated.
亜鉛めっき鋼板の高速溶接においては、上記亜鉛の影
響とガスシールド性の低下による窒素ガス吸収とが重畳
してピット・ブローホールが著しく発生し易くなる。In high-speed welding of galvanized steel sheets, the effects of zinc and the absorption of nitrogen gas due to a decrease in gas shielding properties are superimposed, and pits and blowholes are more likely to occur.
更に、薄板の溶接では継ぎ手形状も重ねすみ肉等の鋼
板表面の影響を受け易い形状が用いられるため欠陥が発
生し易い条件下にある。Furthermore, in the welding of thin plates, the shape of the joint is easily affected by the surface of the steel plate such as overlapped fillet, so that there are conditions under which defects are likely to occur.

However, a solid wire having such a composition cannot be expected to be effective for welding a galvanized steel sheet at a high speed, which is the object of the present invention.

いても蒸気状態でありこれが残存し気泡となる。[Action] As described above, the inventors of the present invention have found that, as described above, particularly in gas shielded arc welding, pits and blowholes are easily generated in a galvanized steel sheet. In addition to promoting, the zinc contained in the molten weld metal is hardly dissolved in iron and has a low boiling point, so that the molten metal is in a vapor state even during the solidification process, and this remains and becomes bubbles.

る。(B) Since shielding performance is reduced in high-speed welding, air is entrained in the welding atmosphere, so that nitrogen is easily absorbed into the molten metal. On the other hand, in the high-speed welding, the solidification speed is high, so that not only zinc gasified in the molten weld metal but also nitrogen gas cannot completely float in the solidification process and easily remains in the weld metal.

る、 と考察した。(C) In gas shielded arc welding, elements with strong deoxidizing power, such as Si, Al and Ti, are added in order to obtain a clean weld metal. However, it was considered that when the deoxidizing action was excessively strengthened, the zinc in the molten state was not oxidized and remained as bubbles, promoting (a).
これら亜鉛や窒素の影響を軽減するには、 （ａ）有害な亜鉛を固定する、或はZnOとしてスラグオ

事が有効であるとの観点からワイヤ組成について鋭意検
討を行い本発明を構成するに至った。From the viewpoint that this is effective, the present inventors have made intensive studies on the wire composition and have arrived at the present invention.

生を抑制するところに最大の特徴がある。That is, the present invention adds an appropriate amount of SiMnAl to activate the oxidation reaction by optimizing the oxidizing power of the weld metal, promote the oxidation of zinc, and increase the temperature of the molten metal by the heat of the oxidation reaction. As a result, the effect of zinc and nitrogen is reduced by decreasing the viscosity of the molten metal and further enhancing the stirring action of the molten metal, thereby facilitating gas release. Furthermore,
The greatest feature is that pit generation is eliminated and blowhole generation is suppressed by the combined action of adding an appropriate amount of Cu, Nb, and V and fixing zinc and nitrogen.
以下に本発明のワイヤの成分限定理由について述べ
る。The reasons for limiting the components of the wire of the present invention will be described below.
ＣはSi,Mnの添加量との兼合いで決まり、本発明のSi,
Mn添加量では0.04％を超えるとブローホール発生には特
に影響はなかったが、溶接部の曲げ延性が低下したので
上限を0.40％以下とした。又、0.02％未満ではピットが
多発したので下限を0.02％とした。C is determined by a balance with the added amount of Si and Mn.
When the amount of added Mn exceeds 0.04%, the occurrence of blowholes was not particularly affected, but the bending ductility of the welded portion was reduced, so the upper limit was made 0.40% or less. If the amount is less than 0.02%, pits frequently occur, so the lower limit is set to 0.02%.
Siは主脱酸剤として添加するが、脱酸力をやや低く調

鉛の酸化を促進し、かつ溶融金属の攪拌作用を強めガス

ーホールの発生を抑制するために使用する。しかし、0.
50％を超えて添加すると脱酸過剰となりピット・ブロー
ホールが多発するので、上限は0.50％とした。また0.10
％未満では基本的に脱酸不足に起因するピット・ブロー
ホールが多発するので下限は0.10％とした。Si is added as the main deoxidizer, but it promotes the oxidation of zinc by increasing the oxygen potential of the molten metal by slightly lowering the deoxidizing power and enhancing the stirring action of the molten metal to facilitate the gas floating. Is used to suppress the occurrence of pit blow holes due to zinc. But 0.
If added in excess of 50%, deoxidation becomes excessive and pits and blowholes occur frequently, so the upper limit was made 0.50%. Also 0.10
If the amount is less than 0.1%, pits and blowholes generally occur frequently due to insufficient deoxidation, so the lower limit was set to 0.10%.
Mnは脱酸剤のみならず溶融金属の粘性を低めるために
使用するが、1.50％を超えると粘性が高くなり過ぎガス
放出が不足し、ピット・ブローホールが多発するので、
上限は1.50％とした。又、0.20％未満では脱酸不足とな
るので下限は0.20％とした。Mn is used not only for deoxidizers but also for lowering the viscosity of the molten metal.However, if it exceeds 1.50%, the viscosity becomes too high, gas release is insufficient, and pit blow holes frequently occur.
The upper limit was 1.50%. On the other hand, if it is less than 0.20%, deoxidation will be insufficient, so the lower limit was made 0.20%.
P,Sは割れ性を阻害する元素であり、特に本発明のワ
イヤにおいてはできる限り抑制することが好ましいが、
いずれも0.030％以下であれば目的を達する。P and S are elements that inhibit the cracking property, and it is particularly preferable to suppress as much as possible in the wire of the present invention,
The goal is achieved if both are 0.030% or less.
Cuは、ピット・ブローホール発生に影響を及ぼす影響
の害を軽減するために添加するもので、0.1％以上で顕
著な効果を得る。Cuは多量に添加する程、ピット・ブロ
ーホールの発生防止に効果があるが、1.0％を超えると
耐割れ性を著しく低下させるので上限を1.0％とした。Cu is added in order to reduce the harm of the influence on the generation of pits and blowholes, and a remarkable effect is obtained at 0.1% or more. The larger the amount of Cu added, the more effective it is in preventing the occurrence of pits and blowholes. However, if it exceeds 1.0%, the crack resistance is significantly reduced, so the upper limit was made 1.0%.
Alは、Si・Mnと共に脱酸剤として使用する。特に、高
速溶接ではシールド性が低下し、溶接雰囲気中に空気を
巻き込み、溶融金属が著しく酸化され脱酸不足となり易
い。Alは少量の添加により、溶融金属の粘性を損なうこ

最も効果があるが、0.050％を超えて添加すると脱酸過
剰となりピット・ブローホールを多量に発生させるので
上限を0.050％とした。又、0.003％未満では脱酸効果が
不足し、溶接部の健全性を損なうので下限を0.003％と
した。Al is used as a deoxidizing agent together with Si · Mn. In particular, in high-speed welding, the shielding properties are reduced, air is entrapped in the welding atmosphere, and the molten metal is liable to be significantly oxidized, resulting in insufficient deoxidation. Al is most effective in preventing excessive oxidation due to air entrapment without impairing the viscosity of the molten metal by adding a small amount, but adding more than 0.050% results in excessive deoxidation and increases the amount of pits and blowholes. , The upper limit was made 0.050%. On the other hand, if it is less than 0.003%, the deoxidizing effect is insufficient, and the soundness of the welded portion is impaired, so the lower limit was made 0.003%.
Ｏは、溶融金属の粘性を低下させ、亜鉛及び窒素ガス
のガス放出を促進させる目的で添加し、0.005％以上の
添加でピット・ブローホールの発生の軽減する効果を有
する。Ｏは多量に添加するほど好ましいが、0.050％を
超えると立向下進溶接時に溶融金属の垂れ落ちが発生す
るので、上限を0.050％とした。O is added for the purpose of lowering the viscosity of the molten metal and promoting the release of zinc and nitrogen gas, and has an effect of reducing the occurrence of pit blow holes by adding 0.005% or more. O is more preferably added in a large amount, but if it exceeds 0.050%, dripping of the molten metal occurs during vertical down welding, so the upper limit was made 0.050%.
Nb・Ｖは、高速溶接時に特有のガスシールド性低下に
よる空気の巻き込みによる窒素ガス吸収によるピット・
ブローホールの発生を抑制する効果を有する。Nb・Ｖの
いずれも0.10％以上でピット・ブローホールの発生を抑

しても同じ様に有効である。しかし、1.50％を超えて添
加すると溶接金属部が著しく硬化し、延性を損なうので
上限を1.50％とした。Nb · V is a pit due to absorption of nitrogen gas due to entrainment of air due to deterioration of gas shielding property peculiar to high-speed welding.
It has the effect of suppressing the occurrence of blow holes. Since the occurrence of pits and blowholes is suppressed at 0.10% or more for each of Nb and V, the lower limit is set to 0.10%. Also, the combined addition of Nb · V is similarly effective. However, if it is added in excess of 1.50%, the weld metal portion is significantly hardened and ductility is impaired, so the upper limit was made 1.50%.
このように構成された成分のワイヤを用いて、CO2ま
たはArにCO2などを混合したシールドガスを用いて亜鉛

ブローホールの発生も非常に少なく構造物用として十分
満足するものである。No pits are generated even when galvanized steel sheets are welded at high speed using a shielding gas in which CO 2 or Ar is mixed with CO 2 etc. This is also very low and is sufficiently satisfactory for structures.
