Özet

In this study, AISI 430 ferritic stainless steel sheets with dimensions of 200x50x2.5 mm were joined by TIG (Tungsten Inert Gas) methods and the tensile properties and microstructure properties of the joined materials were investigated. Microstructure analyses and tensile tests of specimens joined by TIG welding were performed with SEM and TS 287 EN 895 standard, respectively. In microstructural studies, it was determined that a significant grain coarsening occurred in the heat affected zone (HAZ) AISI 430 ferritic stainless steel. Tensile strength, yield strength and elongation of the specimens decreased after TIG welding process.
