Scanning Vibrating Electrode Technique as an application for measuring corrosion activity of carbon steel welded pipelines

摘要

The scanning vibrating electrode technique, also known as SVET, is a relatively new technique which offers the opportunity to obtain information concerning corrosion activity on a small scale. However, its utilisation to investigate the corrosion of welds has been limited. SVET experiments were carried out on specimens of different welded sections within two different electrolytes, e.g., 0.35% NaCl solution alone and buffered 0.35% NaCl solution with CO{sub}2 saturations. SVET was used during these investigations to evaluate preferential corrosion susceptibilities of weldments.
