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.

本数据集包含论文《采用高速X射线成像的搅拌摩擦焊过程物料流可视化》（*Material Flow Visualization during Friction Stir Welding using High-Speed X-Ray Imaging*）的原始文件与实验细节。本研究采用高速X射线成像（High-Speed X-Ray Imaging）技术对搅拌摩擦焊（Friction Stir Welding, FSW）过程进行原位动态捕捉，以高强度X射线束对2 mm×2 mm的区域以20000帧每秒的帧率进行成像。本次实验采用的搅拌摩擦焊（FS）工具由H13模具钢制成，探针带有螺纹与三个平面，实验工件为6061-T6铝合金。本次实验采用的工艺参数可制备得到完全致密的焊件，未观测到任何亚表面孔隙缺陷。高强度X射线束捕捉到的密度变化表明，在工具旋转一周的过程中，其后方空腔会形成并被填充三次。

本共享数据集包含以下文件与文件夹：
1) 横截面数据：内含搅拌摩擦焊试样的横向与轴向横截面视图。
2) X射线静帧图像：包含搅拌摩擦焊过程中采集的3000帧X射线静帧图像。
3) 实验设置文件：包含搅拌摩擦焊工具、焊接参数与成像参数的相关信息。
4) 补充视频文件：该视频文件经ImageJ软件处理完成，通过虚拟堆叠模式将3000帧图像导入为图像序列。
