In Grade2XL, RAMLAB has developed a real-time anomaly detection system (MaxQ) suitable for multimaterial wire arc additive manufacturing.
This innovative system includes: a torch with a 3D scanner and a thermal camera to control the geometry and interpass temperature, a High Frequency Voltage Inverter (HF VI) robot data access for position coordinates and welding parameters and optionally a spectroscope, a microphone and melt pool camera. The system can trace anomalies in real time such as wire feeding problems or a worn out torch tip, and can also give out the intensity ratio between elements (compositional analysis). A closed loop control system is currently under development.
