| description | This research aims to find an inexpensive solution for the problem of welding stainless steel. Cheaper grade stainless steel is popular in Southeast Asia. In this present study, weld bead shape, microstructure, mechanical properties and corrosion behavior of SUS 201 austenitic stainless steel weld joint through the GTA welding process with filler metal grade RE 310 SS are studied. Welding was undertaken under four different conditions with shielding gases at 100%Ar, 1%H2 + 99%Ar, 3%H2 + 97%Ar and 5%H2 + 95%Ar were compared. The results gained from this investigation indicate that the weld joint mixtures of hydrogen with increased argon shielding gas showed no defects of the weld, increased weld bead size (slightly increased due to the welding speed increased in tandem), reduced delta-ferrite, decreased hardness and ultimate strength. However, the pitting corrosion area occurred at the interface between the delta-ferrite phase and the austenite phase because of low chromium in this region. |
