Presentation Transcript

  1. How to convert high-speed images of a welding arc in to time-resolved 2D temperature profiles IIW 2014 SG212 "Physics of Welding"

  2. Diagnostics Spectrometer with Intensified Camera High-Speed Camerawith Filter (HSC)

  3. Diagnostics + high accuracy - 1D - slow - heavy and big set-up • lower accuracy due to image processor low dynamic range • + 2D • + fast • + smaller and lighter set-up

  4. Diagnostics Necessary to confirm the results from the HSC

  5. Set-Up Calibration to determine the exact position of measurement Field of view of the High-Speed Camera: 8 mm Measuring position of the spectrometer: 3 mm
