TLDR
In this article, the importance of type, concentration, and temperature of the electrolytic solution, potential, test duration, and the sulfur content of the steel in the accelerated corrosion test and the susceptibility of steels to grooving corrosion are described.Abstract:
When exposed to neutral, salt-containing waters, electric resistant welded pipe in carbon and low alloy steels with increased sulfur contents may suffer preferential corrosion attack in the weld area. Because of its appearance, this type of corrosion is called grooving corrosion. The susceptibility to grooving corrosion may be determined and quantitatively described by means of an accelerated potentiostatic exposure test. The importance of type, concentration, and temperature of the electrolytic solution; potential; test duration; and the sulfur content of the steel in the accelerated corrosion test and the susceptibility of steels to grooving corrosion are described. Line pipe in high frequency inductive (HFI) welded carbon and low alloy steels are resistant to grooving corrosion particularly because of their low sulfur content.read more

Protectiveness of Corrosion Layers
TL;DR: In this article, the authors summarized experimental and theoretical evidence showing that the protectiveness of corrosion layers can only be due to diffusional transport phenomena in the liquid phase, which gives rise to the new concept of a "liquid surface state".
