Terra Quantum, Empa unveil AI for real-time laser welding prediction

Terra Quantum and Empa have developed an AI model that predicts the 3D temperature and melt-pool shape during laser welding. Trained on detailed simulations, their tool cuts prediction times from over six minutes to just 8 milliseconds at standard resolution. This aims to remove major barriers to real-time process control in industries where weld quality is mission-critical, like aerospace and medical devices.

• LP-FNO model predicts 3D temperature fields, melt-pool boundaries
• Runs up to 100,000 times faster than current simulations
• Trained on titanium alloy simulations for various laser powers, speeds
• Enables real-time digital twins and process optimization
