In this study, microstructural features and mechanical properties of Incoloy 825-316L stainless steel dissimilar joints have been investigated. For this purpose, pulsed gas tungsten arc welding method was employed and 316L, Inconel 82 and Inconel 625 alloys were used as filler metal. First, specimens were cut. Pulsed gas tungsten arc welding was performed using peak and base currents of 220 A a...
This article presents the Laser Beam Direct Energy Deposition (DED-LB) process as a method to build graded austenitic-to-martensitic steel junction. Builds were obtained by varying ratio of two powders during DED-LB processing. Samples with gradual transitions successfully using high dilution rate from one layer next. Long austenitic grains are observed on 316 L side while martensitic Fe–9Cr–1M...
Aircraft skin and stringer elements are typically fabricated from 2xxx 7xxx series high strength aluminum alloys. A single friction stir welding (FSW) pass using a specially designed tool with shoulder/pin diameter ratio (D/d) of 3.20 is used to produce dissimilar T-butt welds between AA2024-T4 AA7075-T6 alloys at constant travel speed 50 mm/min different rotational speeds 400, 600 800 rpm. The...
