Infrared and visual in-situ measurements of components made from AISI 316L in Laser Beam Direct Energy Deposition
Description
The presented dataset comprises a measurement campaign conducted on the laser beam direct energy depositio (DED-LB/M) system LMD² of the University of Kassel.
In DED-LB/M, metal powder is blown into a laser beam, where it is melted and deposited to build up material. Within this campaign, three specimens made of AISI 316L Powder were manufactured.
Each specimen consists of ten adjacent deposited tracks, produced under identical process conditions.
For the measurements, the build table was tilted by 55° to provide the cameras with an improved viewing angle of the process zone.
The manufacturing process was recorded in-situ using three camera systems: a visible RGB camera (Basler ace 2 R PRO) and two midwave infrared (MWIR) cameras (InfraTec ImageIR 8380 hp & Telops MS M3k).
The first MWIR infrared camera (InfraTec ImageIR 8380 hp) captured HDR single-frame images covering a temperature range from 300 to 2000 °C (BlackBody radiation, emissivity = 1) using various optical filters and integration times.
The second MWIR infrared camera (Telops MS M3k) captured eight-frame images from eight different wavelength areas using eight different rotating optical filters.
In addition, the visible RGB camera acquired HDR single-frame images at three different exposure times to robustly capture both very bright and darker regions of the scene.
