(Problem to be Solved by the Invention) However, in the conventional technology, it is said that it is difficult to apply an alkali metal oxide to the surface of a welding wire and ensure that it adheres to the surface of the wire. Because it is flat, it does not have sufficient alkali metal oxide retention ability, and there is a big problem with the uniformity of the amount of coating, and the applied alkali metal oxide only adheres to the wire surface. , during wire feeding, it may peel off from the wire surface and adhere to the spring liner.

(Function) According to the present invention, the porous film 4 provided on the surface of the aluminum plating layer 20 by, for example, anodizing treatment has micropores 3 with a pore size of about 50 to 400 per square inch (for example). 1 to 1000) There are an infinite number of XIO' pieces,
Since these micropores are impregnated with lubricating oil containing fine powder of alkali metal oxide, the surface is coated more uniformly with lubricating oil containing alkali metal oxide than if the alkali metal oxide was applied only to the surface. Moreover, a stable product with less adhesion to the spring liner during wire feeding can be obtained. In addition, compared to those that adhere only to the surface, the alkali metal is impregnated within the very fine pores, so
There is little vaporization at the wire protrusion, and since the alkali metal is effectively contained in the arc, it can be reliably sprayed.
