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

  2. Overview Motivation G. Gött, IIW 2014 Seoul (SG212), July 14th 2014

  3. Motivation Spectroscopic analysis of arcs is widely used Gives accurate 16-bit data 1D spectra with low repetition rate Spectral selective high-speed imaging gives 2D-T (temperature) profiles which result in a better understanding of the arc structure High repetition rate G. Gött, IIW 2014 Seoul (SG212), July 14th 2014

  4. Set-up Object MIF Lens CCD Metal-Interference Filter or Monochromator N:\Projekte\2012\2012_DD9198-Sp_AiF-Gase\03_Publications(Veröffentlichungen)\201407-IIW-Seoul\Vortrag\Abbildungen\Sceme-Setup\All.svg G. Gött, IIW 2014 Seoul (SG212), July 14th 2014

  5. Effect of the Filter N:\Projekte\2012\2012_DD9198-Sp_AiF-Gase\03_Publications(Veröffentlichungen)\201407-IIW-Seoul\Vortrag\Abbildungen\Spectrum.opj G. Gött, IIW 2014 Seoul (SG212), July 14th 2014

  6. Effect of the Filter (Metal-Interference Filter) Filter transmits only Ar-atom lines Metal lines from the overexposed core-region are blocked N:\Intern\OptischeFilter\Metallinterferenzfilter\Filterkurven_E56_Gött-Kozakov\MIF811_488.opj G. Gött, IIW 2014 Seoul (SG212), July 14th 2014

  7. Effect of the Lens Object MIF Lens CCD Each pixel represents a sensor with spatial resolution G. Gött, IIW 2014 Seoul (SG212), July 14th 2014
