Investigation of possibility to use spectrometry for monitoring the plasma in gas shielded arc welding

Investigation of the plasma arc by using optical spectrometry has been performed in TIG and MAG welding. Two different spectrometer setups were tested. The aim was to detect defects such asporosity (gas flow variations), bad penetration, burn through defects and undercuts etc. by using spectrometry....
