This paper present the results of a research concerning the corrosion of the welding zones of the pipes used for the circulation of the technological water in an oil extracting installation. In the first part, the authors present the characteristic of the materials existing in welding zone and of the technological water, general considerations concerning the electrochemical process that is developing as effect of the contact between the metal and the liquid, with a specific chemical composition. The comparison between the recommendations for the welding procedure exiting in the quality norms and the reel quality of the welding zones of the pipes indicate a good concordance. In this case, the conclusion who results is that the environment conditions are very aggressive, and their effects require the continuation of the research.
