【発明の詳細な説明】
［産業上の利用分野］
本発明は、溶接ワイヤの製造方法の改良に関する。 こ
の発明は、ＭＩＧ溶接に用いるステンレス鋼製ソリッド
ワイヤの製造に適用したとき、とくに有用である。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a method for manufacturing a welding wire. This invention is particularly useful when applied to the production of stainless steel solid wires used in MIG welding.
［従来の技術］
一般に、アーク溶接用のワイヤには、それを使用して溶
接を行なったときに、溶接作業性がよいこと、すなわち
アークが安定でありスパッタの発生量が少ないこと、お
よび形状良好なビードが得られること、が要求される。[Prior Art] In general, wires for arc welding are required to have good welding workability when welding using them, that is, the arc is stable and the amount of spatter generated is small, and the wire has a good shape. It is required that a good bead be obtained.
この要求にこたえるため、ワイヤ材質とくに不純物の許
容量や、表面潤滑剤の種類、適切な使用量などが検討さ
れている。In order to meet this demand, consideration is being given to the wire material, especially the allowable amount of impurities, the type of surface lubricant, and the appropriate amount to use.
アーク溶接の作業性に関して、理由は明らかでないが、
Ｃａの存在が悪影響を与えることが知られたので、ワイ
ヤからＣａを極力排除すべきことになった。 それには
まず、ワイヤ材料の製造に当って、原料と精錬の条件を
えらぶことによりＣａを実質上含有しない線材を用意す
ることが有効であり、これを実施することに困難はない
。Regarding the workability of arc welding, although the reason is not clear,
Since it has been known that the presence of Ca has an adverse effect, it has become necessary to exclude Ca from the wire as much as possible. First of all, it is effective to prepare a wire rod that does not substantially contain Ca by selecting raw materials and refining conditions when manufacturing the wire material, and there is no difficulty in implementing this.
問題は、製造工程におけるＣａの付着をいかに防ぐかで
ある。The problem is how to prevent Ca adhesion during the manufacturing process.
溶接用ワイヤの製造工程で、線材圧延に続く伸線は冷間
引抜きによってあり、その潤滑剤として、ステアリン酸
カルシウムのような「金属石鹸」が、その高い潤滑効果
を評価され常用されている。In the manufacturing process of welding wire, the wire drawing that follows the rolling of the wire is performed by cold drawing, and "metal soaps" such as calcium stearate are commonly used as lubricants because of their high lubrication effects.
直径５．５ｍの線材から需要の多い直径１．２Ｍのワイ
ヤに伸線する場合に例をとると、代表的な手法では１２
パスにわたりダイスを通す。 前半の６パスを終って径

てステアリン酸カルシウムを使用する。 コイルにした
ワイヤは有機溶剤中で超音波を当てて洗浄し、付着した
潤滑剤を除去する努力をしているが、なおワイヤ全体と
しては２ｏｐｐｍ程度のＣａが残存することは避けられ
ず、その影響をなくすことはできない。For example, when drawing a wire with a diameter of 5.5 m to a wire with a diameter of 1.2 m, which is in high demand, a typical method uses 12
Throw the dice over the path. After the first six passes are completed and the diameter is 2.2 m, it is customary to perform annealing and move on to the second half of the six passes, in which calcium stearate is used as a lubricant. Efforts are being made to clean the coiled wire using ultrasonic waves in an organic solvent to remove the attached lubricant, but it is inevitable that about 2 oppm of Ca remains in the wire as a whole. The impact cannot be eliminated.
（発明が解決しようとする課題１
本発明の目的は、上述のような技術の現状を打破して、
Ｃａの存在がワイヤの溶接作業性に及ぼす悪影響をなく
した溶接ワイヤを製造する方法を提供することにある。(Problem to be solved by the invention 1) The purpose of the present invention is to break through the current state of technology as described above,
It is an object of the present invention to provide a method for manufacturing a welding wire in which the presence of Ca eliminates the adverse effect that the presence of Ca has on the welding workability of the wire.
［課題を解決するための手段］
本発明の溶接用ワイヤの製造方法の第一の態様は、Ｃａ
を実質上含有しないワイヤ材料を使用するとともに、冷
間引火きによる伸線加工の潤滑剤として高級脂肪酸アル
カリ塩を使用することを特徴とする。[Means for Solving the Problems] A first aspect of the method for manufacturing a welding wire of the present invention is that Ca
The present invention is characterized in that it uses a wire material that does not substantially contain , and uses a higher fatty acid alkali salt as a lubricant for wire drawing by cold ignition.
高級脂肪酸のＮａ塩は、いうまでもなく「石鹸」であっ
て、Ｋ塩は「カリ石鹸」とよばれている。Na salts of higher fatty acids are, needless to say, "soaps", and K salts are called "potash soaps".
以下、あわせて「アルカリ石鹸」という。Hereinafter, they are collectively referred to as "alkaline soap".
第二の態様は、Ｃａを実質上含有しないワイヤ材料を使
用するとともに、冷間引火きによる伸線加工の潤滑剤と
して金属石鹸を使用し、ただし多段伸線ダイスの終段側
の少なくとも１パスにおいては金属石鹸に代えて潤滑油
を使用することを特徴とする。The second embodiment uses a wire material that does not substantially contain Ca, and uses metal soap as a lubricant for wire drawing by cold flashing, provided that at least one pass on the final stage side of a multistage wire drawing die is used. The feature is that lubricating oil is used instead of metal soap.
第三の態様は、第二の態様において、伸線後に洗浄を行
なってワイヤ表面に付着した潤滑剤を極力除去すること
、具体的には１０ｐｐｍ以下にすることを特徴とする。A third aspect of the second aspect is that the lubricant adhering to the wire surface is removed as much as possible by cleaning after wire drawing, and specifically, the lubricant is reduced to 10 ppm or less.
［作 用］
アルカリ石鹸は、その冷間引抜ダイスへの潤滑効果がス
テアリン酸カルシウムのような金属石鹸に及ばないため
、従来はかえりみられなかったが、なお潤滑剤として有

発明者は確認した。 後記する実施例にみるように、伸
線後に洗浄を行なわないとＮａ （またはＫ）の付着
量は３０１）ｌ）ｍ以上に達するが、溶接作業性は損わ
れない。[Function] Alkaline soap is still useful as a lubricant, although its lubricating effect on cold drawing dies is not as good as that of metal soaps such as calcium stearate, so it has not been used in the past. The present inventors have confirmed that, unlike Ca, even if a large amount of Na remains on the wire, it does not have an adverse effect on welding workability. As shown in the examples to be described later, if cleaning is not performed after wire drawing, the amount of Na (or K) deposited will reach 301)l)m or more, but welding workability will not be impaired.
しかし、洗浄によりアルカリ石鹸の付着量を低減するこ
とは好ましい。 周知のとおりアルカリ石鹸は水に対す
る溶解度が高いから、有機溶剤と超音波の組み合わせに
よらず温水で洗うだけでも、容易に付着量を低減するこ
とができる。 発錆の問題のないステンレス鋼溶接ワイ
ヤにおいては、温水洗浄は有利な潤滑剤除去法である。However, it is preferable to reduce the amount of alkaline soap deposited by washing. As is well known, alkaline soap has a high solubility in water, so the amount of adhesion can be easily reduced by simply washing with warm water, without using a combination of organic solvent and ultrasonic waves. For stainless steel welding wires that do not have rusting problems, hot water cleaning is an advantageous lubricant removal method.
ステアリン酸塩の潤滑効果で比較した場合、Ｃａ塩とＮ
ａ塩とは、ダイス寿命にしておおよそ１００ ： ７０

油を使用する。When comparing the lubricating effect of stearate, Ca salt and N
A salt is approximately 100:70 in terms of die life.
There is a difference of ~80, and some of the effects of metal soap are difficult to discard. Therefore, in the second and third aspects of the manufacturing method of the present invention, C is used as a lubricant for the wire drawing die, as described above.
a. Use soap, but omit it for the final pass, preferably the second pass, and use a liquid lubricant, typically oil.
前記したように金属石鹸は洗浮によっても除去しにくい

施する洗浄工程で有は溶剤中へ分散することが容易にな
り、その結果として除去率が高くできると考えられる。As mentioned above, metal soap is difficult to remove even by washing, but in this second embodiment, when the wire material is squeezed with a die, a large amount of the metal soap attached to the wire surface is removed. The residue also mixes intimately (perhaps on a molecular level) with the liquid lubricant, making it easier to disperse it into the solvent during the cleaning step carried out in the third embodiment, resulting in a high removal rate. It seems possible.
［実施例］

ＵＳ４３０系、社内規格Ｗ３４４２Ｍ）の熱間圧延によ

A wire rod with a diameter of 5.5 m was obtained by hot rolling of US430 series (in-house standard W3442M).
