The wire beam electrode (WBE) method was employed to study water-line corrosion of carbon steel under static condition. It was found that, it was the thin electrolyte film that aggravated the corrosion of steel in water-line area, not the difference of oxygen concentration. The difference of oxygen concentration decided the location of cathode, which was near waterline, and the regularity of vertical current distribution under waterline. Besides, it was also found that, in water-line area, the peak of corrosion rate was located at about half of the region just below the waterline.
