The most common method of manufacturing a 0 mm thin wire is a process of drawing a wire after wire or flux filling to a diameter of 2 to 4 mm by a roller or a hole die, annealing process, pickling process, plating process, final process. This is a method in which the step of drawing with a hole die to the size diameter is selected and sequentially performed according to the shape and physical properties of the product. In the step of drawing to the final size diameter, the wire is generally produced by a wet drawing with a smooth surface state and a good color tone. However, in wet wire drawing, since a water-soluble lubricant is generally used, the wire surface coating is thin when passing through the dice, and the slipperiness of the wire is somewhat poor. However, there is a slight problem in efficiency because it is necessary to use many dies.

にある。On the other hand, in the case of dry wire drawing, if metal soap or the like is used as a lubricant, the area reduction rate can be increased, but a lubricant removal treatment (eg, baking treatment) is required after wire drawing. In the case of an inorganic or anhydrous lubricant that does not require a baking treatment, there is a problem that the lubricant is difficult to be uniformly applied to the surface of the wire and that a flaw is generated on the surface of the wire. In addition, these arc welding wires tend to adopt welding conditions at higher currents as the automation and efficiency of welding progress, and as a result, the wire feeding speed is inevitably increased. Become. In addition, depending on the target structure, welding is often performed in narrow areas, and from the viewpoint of ease of use in these places, the conduit cable from the feed roller of the wire feeder of the welding machine to the welding torch is used. Tend to be bent.

塗布する方法等、各種の方法が提案されている。[0004] When the conduit cable is bent and used as described above, the frictional resistance increases when the wire passes through the conduit tube in the conduit cable, which hinders the feeding of the wire during welding and causes unstable arcing. This causes a problem that welding cannot be performed. Conventionally, problems such as drawability during production of these arc welding wires and feedability during welding have been addressed, for example, in Japanese Patent Publication No. 58-4639.
JP-A-5-237 discloses a method in which higher fatty acids and alkali metal salts of higher fatty acids are wet-drawn with a lubricant diluted with a volatile solvent, and an appropriate amount of the lubricant is applied to the wire surface.

Various methods have been proposed, such as wire drawing with a lubricant made of graphite or the like and a method of applying the lubricant.

The surface may be scratched. Further, at the time of welding, it is still insufficient at present to improve the wire feedability when a long conduit cable is used and welding is performed under high current welding conditions.

に潤滑剤が付着するので好ましい。The step of drawing using a lubricant obtained by mixing an ester composed of a fatty acid and an alcohol or an animal or vegetable oil with an inorganic or anhydrous lubricant may be performed after plating, after annealing if not plated or after wire diameter. When the thickness is set to 4.0 mm or less, the lubricant is uniformly attached, so that the drawability is improved. In addition, even if the wet drawing is performed after the drawing, the drawing can be performed with the lubricant adhered, so that both the drawing property and the wire feeding property during welding are good. It is preferable to use a rotary die as a die used for wire drawing, because the lubricant can be more uniformly attached.
