原始语种摘要: ABSTRACT(#br)API X70 steels are used for manufacturing and constructing pipes for transporting hydrocarbons; however, they deteriorate over time due to the environment to which they are exposed; influencing the rate and type of corrosion on the surfaces of the base metal (BM), heat-affected zone (HAZ) and fusion zone (FZ). In order to find out and evaluate the susceptibility to corrosion in joints made from API X70 steel subjected to different corrosive media, various tests were carried out using the process of double submerged arc welding, which were immersed in different electrolytes: sodium chloride (3.5% NaCl) and water (H2O) at ambient temperature in order to find out about behaviour. Electrochemical noise techniques and cyclic polarization curves were used to obtain the...
