Weld Geometry, Mechanical Properties, Microstructure and Chemical Composition of AA6063 in Tungsten Inert Gas Welding with Intermittent Controlled Wire Feeding Method

In this study, AA 6063 aluminum was joined using Tungsten Inert Gas (TIG) welding with a butt joint. The ER-5356 filler metal feeding method is used intermittently to find its effect on weld geometry, mechanical properties, microstructure, and chemical composition. dimensions of the specimens in study were 120 mm × 50 mm, thickness 3 mm. ratio configuration feed time delay time. length wire varied from 4 6. top bead width back decreased by 17.66% 40.33%, respectively. At 6, it has largest cross-sectional area 295.37 ± 27.60 mm2. results show that general tensile strength proportional ratio, but difference not significant, only around ±8 MPa. microstructure formed each different characteristics; conversely, grains relatively coarse structure have hardness values. composition test shows directly correlates magnesium’s average weight content, where content magnesium value tends be homogeneous all areas (WM).
