摘要:
Disclosed herein is a surface treatment oil for treating the surface of a welding wire. The surface treatment oil comprises at least one alkali metal compound and/or an alkaline earth metal compound, a Zn compound, and a hydrocarbon compound wherein the hydrocarbon compound contains at least two functional groups selected from the group consisting of ester, carboxylic acid, alkane and sulfonic acid groups. Further disclosed is a welding wire surface treated with the surface treatment oil. The surface treatment oil can provide good rust resistance, wear resistance, arc stability and wire feedability to a welding wire when being applied to the surface of the welding wire.

Disclosed herein is a copper-free wire for gas-shielded arc welding. The copper-free wire for gas-shielded arc welding comprises a flat worked surface, and depressions circumferentially formed in a negative direction (towards the center of the wire) to the said worked surface reference. The ratio (dr/di) of an actual length (dr) of a circular arc to an apparent length (di) of a circular arc is in the range of 1.015 ~ 1.515. An amount of lubricant remaining on the wire surface is 0.50 g/W. kg or less. The wire has 0.03 ~ 0.70 g/W. kg of a coating agent on the wire surface. The coating agent comprises at least one selected from the group consisting of liquid animal oil, vegetable oil, mineral oil, mixed oil, and synthetic oil. The wire is brought into stable contact with a contact tip during welding, which results in excellent arc stability and feedability, while lowering a spatter quantity.
