| Abstract Scope |
Real-time monitoring is desired to reduce the time and money required to evaluate parts in wire arc additive manufacturing processes. This work focuses on in-situ process monitoring of a Lincoln Electric SculptPrint RND system using weld pool dimensions and temperature measurements of the part. A video camera is attached to a robot arm and pointed at the weld pool to monitor weld pool characteristics, and an IR camera is placed at a static location next to the part to monitor heat build-up across the build geometry. Temperature and weld pool measurements are monitored for inconsistencies using machine learning algorithms and data is compared to defects identified after printing to correlate process variables with defect formation. Key process variables are identified for developing process maps and defect-free process windows. |
