However, this technique has not been used for studies in structures susceptible to corrosion. In addition to changing the microstructure, it is expected that this technique increases the corrosion resistance of the edge of the weld bead which is a vulnerable region to corrosion. Moreover, the machining technique has been widely used to improve the workpieces finishing and/or structures that have been subjected to repair by welding, improving the surface roughness, increasing the corrosion resistance of these structures when subjected to aggressive environments. Thus, this work will study the effects of finishing techniques using machining and welding on the edge of the weld bead joints of 410D ferritic stainless steels, making an evaluation by mass loss in the samples which will be subjected to corrosion by immersion in NaCl containing medium. It is expected that the finishing techniques can relieve tensile stresses increasing the corrosion resistance. 2019 artículo científico 1806-2563 https://www.redalyc.org/articulo.oa?id=303260200038 https://www.redalyc.org/journal/3032/303260200038/ https://www.redalyc.org/journal/3032/303260200038/html/ https://www.redalyc.org/journal/3032/303260200038/303260200038.epub https://www.redalyc.org/journal/3032/303260200038/movil https://doi.org/10.4025/actascitechnol.v41i1.37732 pt http://www.redalyc.org/revista.oa?id=3032 Acta Scientiarum.
