- Hydrogen Sulfide Corrosion of Weld Regions in API X52 Steel L.F Arenas-Martínez G. García-Cerecero Ingeniería GMAW X52 steel corrosion Weld regions hydrogen sulfide The corrosion behavior of gas metal arc welding (GMAW) regions has been studied using potentiodynamic polarization and polarization resistance (LPR) techniques. Experiments were conducted in hydrogen sulfi de (H2S)- containing brine and in H2S-free brine. Welds were made on API 5L X52 steel. Due to diff erences in their microstructure, chemical composition and residual stress level, weld regions exhibited diff erent responses under H2S corrosion. Base metal exhibited the highest corrosion rate (CR) and the most cathodic corrosion potential. 2012 artículo científico 1405-7743 https://www.redalyc.org/articulo.oa?id=40424505010 en http://www.redalyc.org/revista.oa?id=404 Ingeniería.
