Description
Summary:Arc welding has proven itself to e an economically affordable and efficient method for the joining of a wide variety of aluminum alloy structures that find extenswive use in the industries of ground transportation and building construction. Welded joints,, having a "T" configuration, in dissimilar Al alloys were produced using the semiautomatic arc welding process. In this study, a combination of a non-heat-treatable aluminum-magnesium alloy and a heat-treatable aluminum-magnesium-silicon alloy was successfully welded. Optical microscopy was used to characterize the fusion zone microstructures of the fillet-welded T joints. The intrinsic microstructural features and the development and presence of defects are highlighted. Alloys: 6061 and 5083.
