<p>Description of dataset 10.5281/zenodo.4061502</p> <p>Deposition of Inconel 718 square spiral with process parameters:<br> - Nominal power = 300 (W)<br> - Nominal velocity = 600 (mm/min)<br> - Powder flux = 0.0825 (g/s)<br> - Spiral size: 60 mm side, 3 mm step<br> - Nr. nozzles = 4<br> - Argon carrier flux = 4 (l/min)<br> - Argon shielding gas flux = 15 (l/min)<br> - Substrate temperature = Ambient</p> <p>This experiment took place on the same substrate of 10.5281/zenodo.4049842 (on the &quot;left&quot;) and follows the same part program. In this case, the laser spot is slightly off-center in camera images.</p> <p>The dataset is constituted by:<br> - Melt pool images, in file Deposition_2020_07_31__13_09_50.zip, acquired at 200fps with 850 nm narrow band filter, 1ms exposure time. 400x400 px size<br> - trackData_20200731_left.csv containing:<br> &nbsp;&nbsp; &nbsp;- t: timestamp in ms.
