Abstract Scope |
The AMB2022-03 benchmark explores a range of individual and overlapping melt pool behaviors using individual laser tracks and 2D pads on bare IN718 plate. Single track laser scans were created with several combinations of laser power, scan speed, and spot diameter. Two 2.5 mm × 5 mm pad scans were created by scanning the laser in the ±X-direction and ±Y-direction. Then, the in-situ thermographic and laser coupling measurement approaches, data processing steps, and results will be presented. In addition to evaluation of the measurement uncertainty, a sensitivity study of the measurement results to the test uncertainty (uncertainty of process parameter values) will also be described. An overview of the machine process parameter measurements (including laser power, scan speed, and spot diameter, and more) will be given. Finally, the measurement results will be compared with anonymized challenge submission results from modelers to show the relative accuracy or trends in the models.
