ある。2. Description of the Related Art Conventionally, it has been reported that when a trace amount of a metal having a low potential gradient such as cesium, sodium and potassium is attached to the wire surface, the arc discharge phenomenon is stabilized and the welding performance is improved. Further, as a method of adhering the metal to the wire surface, as shown in JP-A-60-231599, a powdery or solid potassium carboxylic acid salt is mixed with a dry lubricant on the wire surface and used. Finishing wire drawing as a finishing step after copper plating treatment by a method of mechanically fixing by a finishing wire drawing as a finishing step after copper plating treatment or using a wet lubricant containing potassium carboxylate etc. There is a method of mechanically fixing them.

As described in JP-A-231599, as components of a dry lubricant, "potassium oleate, potassium salts such as potassium palmitate, sodium salts such as sodium oleate, sodium palmitate, sodium stearate, graphite, sulfur, etc. , Talc, Zn-DTP and other extreme pressure additives and antifriction agents must be mixed appropriately.

である。その理由は、これ等極圧添加剤や減摩剤の量を
少なくすると、仕上伸線用のダイスの摩耗が激しくな
り、著しく生産性が低下してしまうからである。However, since the extreme pressure additives and antifriction agents as described above are mixed, the wire surface after dry finishing wire drawing should include the above-mentioned extreme pressure additives and antifriction agents in addition to the required carboxylic acid potassium salt, etc. There was a drawback that the agent was also fixed at the same time. As a matter of course, substances contained in these extreme pressure additives and lubricants adversely affect the weld metal after welding. For example, sulfur, Zn, or the like may generate gas during welding, remain as bubbles in the deposited metal, and may cause defects such as blowholes. Further, in such a conventional method, it is extremely difficult to control the extreme pressure additive and the lubricant to such an extent that they do not affect the welding result. The reason is that if the amounts of these extreme pressure additives and antifriction agents are reduced, the die for finish wire drawing becomes severely worn, resulting in a marked decrease in productivity.

分を完全に除去する事は容易ではない。On the other hand, the latter method using a wet lubricant can solve the above-mentioned problems, but when a wet lubricant is used, its water content is inferior in rust prevention and at the time of wire feeding. Also lacks lubricity. Therefore, in order to obtain excellent wire rust prevention and wire feedability, it is necessary to apply an oil-based lubricant after finishing wire drawing, but the adhesion of potassium carboxylic acid salts etc. to the wire surface and the oil-based lubricant Since the coating is performed in a separate step, the adhesion of potassium carboxylate or the like may vary, and it is not easy to completely remove the water contained in the wet lubricant.

It is a wire for gas shielded arc welding with 10g held and adhered.

任意に混入することが可能である。In addition, it is possible to adjust the amount of the carbon to be retained and attached to the wire by adjusting the concentration of the carboxylic acid potassium salt or the like (for example, potassium stearate) in the oil-based lubricant. In addition, since carboxylic acid potassium salt and the like act as an organic corrosion inhibitor, they have an anticorrosion effect in an atmosphere of high temperature or strong acidity. However, since the effect is lost when neutral to alkaline, as a countermeasure against this, it is also possible to mix an inorganic corrosion inhibitor into the oil-based lubricant, which enhances the corrosion prevention effect of the entire wire. I can.
As the inorganic corrosion inhibitor, nitrous acid and the like can be used, but in this way, in the oil-based lubricant, other substances within a range that does not adversely affect the welding performance and the welding result,
It is possible to mix it arbitrarily.
