Abstract

Devices, systems, and methods for calibrating for an electron beam additive manufacturing system. The electron beam manufacturing system includes electron beam guns. A calibration system includes an optical pyrometer. The optical pyrometer captures thermal radiation emitted from raw material. An analysis component is communicatively coupled to the optical pyrometer. The analysis component is programmed to determine calibration parameters from information from the optical pyrometer and a phase transition temperature.
