Example open access datasets for low-alloy structural steel weld metals, previously published in ref. [1]. The datasets are also related to the International Institute of Welding Commission C-IX, document nr. IX-L-1239-2021. Files included: The nomenclature of the files corresponds to what is used in ref. [1]. CV_3.crc/cpr: Conventional arc weld, 3/5 mm t-joint HY_1.crc/cpr: Laser-hybrid weld, 3mm butt-joint LA_1.crc/cpr: Laser weld, 3mm butt-joint The methodology for analysing grain size and dislocation sub-structures is found at: https://zenodo.org/record/5053377 and https://doi.org/10.5281/zenodo.4430623 For further information visit: Aalto University Wiki - https://wiki.aalto.fi/display/GSMUM and https://wiki.aalto.fi/display/EMDIDS Refererences: [1] Materials Science and Engineering: A, 2014; 592: 28-39, http://dx.doi.org/10.1016/j.msea.2013.10.094 [2] Welding in the World. 2016; 60: 673-678. http://dx.doi.org/10.1007/s40194-016-0318-8 [3] Ultramicroscopy 2021, Volume 222, https://doi.org/10.1016/j.ultramic.2021.113203
