Abstract

DC60 (08/06/42) Welding electrodes improved wetting between the weld metal and the surface of the wire, thereby providing Excellent pullability and weldability in welding The wire resistance pattern is arranged, the wire is dipped in the solution. Containing water of alkali sulfides Or aluminum sulfide to generate iron sulphide (FeS2, FeS) on that surface by the weldable nature of the metal used Welded to the skin The wire face will be improved in resistance welding of The resulting wire S in iron sulfide. Where appropriate, it appears at an amount of 0.1-20 atoms%, with the value measured by X-ray photoelectric spectroscopy. Welding electrodes are improved in wet appearance between the weld metal and the surface of the wire, thus providing Excellent pullability and weldability in welding The wire resistance pattern is arranged, the wire is dipped in the solution.
