| contents | Failure analysis of fillet welds with premature corrosion in 316L stainless steel slide gates using constitution diagrams Carlos Mauricio Franco-Rendón Henry León-Henao Álvaro Diego Bedoya-Zapata Juan Felipe Santa Jorge Enrique Giraldo B. Ingeniería WRC Corrosion slide gate 1992 diagram stainless steel The service environment of the slide gates may cause localized corrosion at welds. In this work, a failure analysis was conducted to determine the causes of the premature corrosion of the fillet welds before the commissioning. According to the contractor, the slide gates were manufactured in ASTM A240 Type 316L stainless steel and welded with GMAW using an ER316LSi filler metal. Test samples of the fillet weld metals were extracted from gates after a preliminary visual inspection. The samples were analyzed using ferrite number measurements, Optical Emission Spectrometry, chemical analysis, metallographic examination and Scanning Electron Microscopy with microanalysis. The analysis of results using the Schaeffler and WRC-92 constitution diagrams showed that the estimated chemical composition of the filler metal differs with the filler metal specified in the WPS suggesting that an incorrect carbon steel filler metal was used during the construction of the gates. 2020 artículo científico 1657-4583 https://www.redalyc.org/articulo.oa?id=553768132016 https://www.redalyc.org/journal/5537/553768132016/ https://www.redalyc.org/journal/5537/553768132016/html/ https://www.redalyc.org/journal/5537/553768132016/553768132016.epub https://www.redalyc.org/journal/5537/553768132016/movil https://doi.org/10.18273/revuin.v19n2-2020016 en http://www.redalyc.org/revista.oa?id=5537 Revista UIS Ingenierías application/pdf Universidad Industrial de Santander Revista UIS Ingenierías (Colombia) Num.2 Vol.19 |
