초록
In this study, the mechanical properties of railway-vehicle aluminum under frame was investigated based onthe metal inert gas (MIG) welding conditions. An aluminum-alloy (6005A-T6) extruded material used in thelower panel of a railway vehicle was connected through MIG welding to determine the mechanical properties ofMIG welds. Argon shielding gas and filler materials, such as ER5356 and ER4043, were used as consumablewelding materials. For the welding conditions of the test specimen, welding frequencies of 2.5 and 4.5 Hz wereapplied using the SynchroPuls function, and the root faces were 1.0 and 1.5 mm. The mechanical properties ofthe MIG welds were determined through tensile, bending, and fatigue tests.
