Data indicating melt pool and bulk part temperature during the additive manufacture of a Ti-6Al-4V thin-walled structure via Laser Engineered Net Shaping

An OPTOMEC Laser Engineered Net Shaping (LENS TM) 750 system was retrofitted with a melt pool pyrometer and in-chamber infrared (IR) camera for nondestructive thermal inspection of the blown-powder, direct laser deposition (DLD) process. Data indicative of temperature and heat transfer within the melt pool and heat affected zone atop a thin-walled structure of Ti-6Al-4V during its additive manufacture are provided. Melt pool temperature data were collected via a dual-wavelength pyrometer while the dynamic, bulk part temperature distribution was collected using an infrared (IR) camera. Such data are provided in comma-separated values (CSV) file format, containing a 752 x 480 matrix and a 320 x 240 matrix of temperatures corresponding to individual pixels of the pyrometer and IR camera, respectively. The IR-camera and pyrometer temperature data are provided in blackbody-calibrated, raw forms. Provided thermal data can aid in generating and refining process-property-performance relationships between DLD and its fabricated materials.
