LMD Inconel 718 Spiral 2020-07-31 left

Description of dataset 10.5281/zenodo.4061502

Deposition of Inconel 718 square spiral with process parameters:
- Nominal power = 300 (W)
- Nominal velocity = 600 (mm/min)
- Powder flux = 0.0825 (g/s)
- Spiral size: 60 mm side, 3 mm step
- Nr. nozzles = 4
- Argon carrier flux = 4 (l/min)
- Argon shielding gas flux = 15 (l/min)
- Substrate temperature = Ambient

This experiment took place on the same substrate of 10.5281/zenodo.4049842 (on the "left") and follows the same part program. In this case, the laser spot is slightly off-center in camera images.

The dataset is constituted by:
- 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

    - t: timestamp in ms. Synchronized with imData_20200731_left.csv
    - Xpos: laser spot X position in workspace
    - Ypos: laser spot Y position in workspace
    - Zpos: laser spot Z position in workspace
    - G1: binary signal indicating active deposition (G1=1) or not
    - D: track width measured at [Xpos(t), Ypos(t), Zpos(t)]
    - H: track heigth measured at [Xpos(t), Ypos(t), Zpos(t)]
    - A: track section area measured at  [Xpos(t), Ypos(t), Zpos(t)]
    - sdres: roughness index of section profile (std. deviation w.r.t. smoothed profile)
    - Vnom: laser spot translational speed in m/s (computed from Xpos, Ypos, Zpos and t data)
    - Pnom: nominal power
    - V: Vnom in mm/min
- imData_20200731_left.csv containing:
    - t: timestamp in ms. Synchronized with trackData_20191205_left.csv (some frames may have been lost)
    - I_mean: mean image intensity (only on red channel)
    - I_mean_crop: mean image intensity computed on central cropped image area (180x180 pixels)
    - M_I_mean: I_mean after application of 8-sample moving average
    - M_I_mean_crop: I_mean_crop after application of 8-sample moving average
