Analysis of the corrosion scales formed on API 5L X70 and The base metal and welded joint of the API5L X70 steel showed lower rates of corrosion in the range of 40 ºC to 60 ºC in the vapour phase and at 80 ºC for the fully immersed condition.
Mar 30, 2021 · Abstract. Friction stir welding (FSW) is an excellent alternative process used in pipelines circumferential welds due to fusion welded joint low corrosion resistance. This study describes the corrosion resistance as a function of the microstructural features resulting from an API X70 FSW welded joint. The microstructural features were examined by optical microscopy, scanning electron microscopy, and x Corrosion Behavior of Welded Joint of Q690 with CMT Twin Jan 01, 2018 · Microstructure samples were machined with 10 mm x 10 mm x 5 mm, which ensured that the specimen contained base metal (BM), heat affected zone (HAZ), and weld zone (WZ). Prior to microstructure testing, the sample was polished sequentially with the number of 120, 240, 400, 600, 800, and 1000 emery papers and then polished to the mirror with 1.5 Corrosion behavior of the weld joint of X80 pipeline steel Mar 23, 2020 · Wang L W, Liu Z Y, Cui Z Y, Du C W, Wang X H and Li X G 2014 In situ corrosion characterization of simulated weld heat affected zone on API X80 pipeline steel Corros.
