な溶接欠陥を招く問題があった。Traditionally, this type of wire has been characterized by its components as well as the physical and chemical properties of its surface, including weldability, especially feedability and welding workability, as well as the mechanical and chemical properties of the deposited metal, appearance, and storage stability. This is said to be a major factor in the quality characteristics of welding wires, and it is said that they must be used in a clean state with no oil, rust, dirt, or dust on their surfaces.However, conventional welding wires do not have sufficient rust prevention properties. The surface is easily rusted, and the contact resistance when passing through the contact jaws and tips is large, resulting in poor feeding performance, resulting in increased seizure and spatter, which can lead to serious welding defects. There was a problem that led to

得られない欠点がある。However, this type of lubricant improves the feedability and rust prevention properties of the welding wire to some extent, and provides good results when welding mild steel, etc., but it is not suitable for welding high-strength steel. cannot be applied to wires used for welding high-strength steel, etc., because the allowable amount of hydrogen in the weld metal is extremely low.
Moreover, it has the disadvantage that sufficient rust prevention cannot be obtained unless it is deposited in a certain amount.
本発明は、上記問題や欠点を解決したもので、その要旨

濃度は４〜１７重量多の範囲内が好適である。When used for wire drawing, if the concentration of the lubricating substance is less than 4 weight φ, the drawability of the wire will decrease, resulting in poor wire drawing efficiency, and if it exceeds 17 weight φ, the amount of adhesion to the surface of the welding wire will decrease. The concentration of the lubricating substance in the emulsion is preferably within the range of 4 to 17% by weight, since this causes problems such as an increase in the amount of hydrogen in the deposited metal.

In addition, if the pH of the emulsion is less than 7.5, the wire surface cannot be sufficiently cleaned and rust-prevented, so it is difficult to obtain good electrical conductivity, and if it exceeds 10.0, it is difficult to obtain good lubrication. is preferably in the range of 7.5 to 10.0.
ｐＨを調整するには、必要に応じて苛性ソーダまたは炭
酸ソーダを適量添加すればよい。To adjust the pH, an appropriate amount of caustic soda or soda carbonate may be added as necessary.
本発明の潤滑剤を使用する場合、予め溶接ワイヤ表面に
薄く付着させて用いるようにしたのは次の理由による。When using the lubricant of the present invention, the reason why it is applied in advance to a thin layer on the surface of the welding wire is as follows.

ましいからである。In other words, if too much lubricant is used, too much of it will adhere to the wire surface, increasing the amount of hydrogen in the weld metal, making it impossible to obtain a high-quality weld, and if the lubricant is excessive, the wire will become sticky and impurities will adhere. This is because it is preferable that the amount of adhesion be as small as possible, since this may cause damage to the contact jaws or chips, and may cause slippage between the feed roller and the wire, resulting in poor workability and deterioration in electrical conductivity.

ある。In this case, the amount of the lubricant of the present invention to be used is determined by the amount of lubricant substance deposited per unit surface area of the wire: DX (2,5 to 83) ■/-m
: The reason for this is that the amount of lubricant applied is 83D.
C7%/m'), the amount of hydrogen in the weld metal is 1.5
CC/100.9 or more, and moreover, it was difficult to wind the wire in an aligned manner due to the failure during wire manufacturing, and the
This is because if the amount is less than 100%, the effect of using a lubricant is not recognized due to the lack of rust prevention and feedability, and problems such as seizure and damage to chips etc. occur during welding.

Emulsions having a pH of 9 were prepared at various concentrations, and each emulsion was used to draw a wire to produce a carbon dioxide arc welding wire A having a diameter of 1.2.
得られた各種ワイヤを用いて各種試験を行なったので、
その試験結果について以下説明する。Various tests were conducted using the various wires obtained, so
The test results will be explained below.

To measure the amount of adhesion (soap and oleic acid), measure the weight of a dried wire, then immerse it in an ether solution to extract the lubricating substance, dry it, and measure the weight of the wire again. The difference was calculated as the amount of lubricant substance deposited.

接用ワイヤＡ、Ａ′に釦けるスプール巻生産性指数を測
定したところ第１図に示す結果が得られた。[Relationship between amount of lubricant deposited and wire productivity] When the spool winding productivity index of the obtained welding wires A and A' was measured, the results shown in FIG. 1 were obtained.

５０■／ｍ’ワイヤのところで最大となり、さらに付着
量が増加すると逆に低下し始め約１００■／ｍワイヤを
こえると１００係以下に低下することがわかる。As is clear from the figure, if the amount of lubricant adhered to is 0 is set to 100, it increases as the amount of adhesion increases and reaches a maximum at about 50cm/m' wire, and as the amount of adhesion increases further, the opposite is true. It can be seen that it begins to decrease to 100 μ/m wire and then decreases to below 100 μ/m wire.
これは付着量が多くなり過ぎるとワイヤ間でスリップし
、整列巻かしにくくなるためである。This is because if the amount of adhesion becomes too large, it will slip between the wires, making it difficult to wind them in alignment.
従って、スプール巻生産性指数の点から潤滑性物質の付
着量はワイヤ径が１．２〆の場合１００ｍ９／ｍワイヤ
以下、すなわち、前記式にかける係数が８３以下である
のが好ましい。Therefore, from the viewpoint of the spool winding productivity index, it is preferable that the amount of the lubricating substance deposited is 100 m9/m wire or less when the wire diameter is 1.2 mm, that is, the coefficient applied to the above formula is 83 or less.

かる。As is clear from the figure, the amount of lubricant deposited is 3 to 4 ■/m even in the low current range and in the high current range.
It can be seen that when the wire is exceeded, the feeding motor terminal voltage suddenly decreases, that is, the wire feeding performance is significantly improved.
従って、ワイヤ送給性を向上させるためには潤滑性物質

わかる。The results obtained are shown in FIG. As is clear from the figure, there is a nearly proportional relationship between the amount of adhesion and the hydrogen content, and in order to make the wire applicable to all steel types and to obtain high-grade weld metal, the hydrogen content in the weld metal must be 2cc/101 Since it must be less than 0.001n9/m wire, it can be seen that when the wire diameter is 1.2φ, the amount of lubricant deposited is preferably 001n9/m wire or less.

が判明した。The above was a test on a 1.2φ wire, and the results were 3 to 100 rru? It can be seen that the one with a /- wire adhesion amount is overall superior, but the optimal range of this adhesion amount differs depending on the wire diameter, and as a result of examining various wire diameters, the absolute value of the adhesion amount is It was found that there is an appropriate thickness of the deposited film, and that the range is expressed by the amount of the lubricant deposited per unit wire surface area, as given by the formula W = DX (2,5-83). .
従って、１．２φ以外のワイヤの場合も、上式を満足す

て述べたと同様の効果がある。Therefore, in the case of a wire other than 1.2φ, the same effect as described for the case of a 1.2〆 wire can be obtained as long as the amount of adhesion is within the range that satisfies the above formula.
さらに、潤滑性物質の濃度を種々に変えた潤滑剤を用い

その結果を第７図むよび第８図に示す。The results are shown in Figures 7 and 8.
