High-Speed High-Energy X-ray Imaging of Friction Stir Welding 6061-T6 Aluminum - Mfg Letters 2022
This dataset contains the raw files and experimental details for the manuscript "Material Flow Visualization during Friction Stir Welding using High-Speed X-Ray Imaging". This study employs high-speed X-ray imaging to capture the process dynamics during FSW in-situ , using a high-intensity X-ray beam to image a 2 mm x 2 mm area at 20,000 frames per second. The friction stir (FS) tool made of H13 tool steel with threads and 3-flats on the probe was used in an aluminum 6061-T6 workpiece. The process parameters employed result in a fully consolidated weldment without any observable sub-surface voids. The density changes captured by the high-intensity X-ray beam show the formation and filling of cavities in the wake of the tool three times per rotation. This shared data contains the following files and folders: 1) Cross-sections: Contains traverse and lateral cross-sectional views of frictions stir welded specimen. 2) X-ray stills: Contains 3000 frames of X-ray still images taken during the friction stir weld. 3) Experimental settings file: Information on friction stir tool, welding parameters and imaging parameters. 4) Supplementary video file The video file was processed using ImageJ software. The 3000 frames were imported as an image sequence using a virtual stacked mode. The data was collected on 6/10/22 by Hemant Agiwal, Mohammad Ali Ansari, Daniel Franke, Patrick Faue, and Frank E. Pfefferkorn. Advanced Photon Source contacts: Samuel J.

Steps to reproduce
Facility access: The X-ray experiments were performed at the Advanced Photon Source at Argonne National Laboratory, USA. The access to beam time is based on proposal acceptance by the national lab. 72-hours (9 shifts) access was provided. Machinery: A 3-axis milling machine (HAAS TM-1) was shipped to the facility and was transferred into the beam line hutch. The friction stir welds were performed on the machine in position control mode. The machine needs to be controlled remotely using trigger switches for operation.
