Abstract
Disclosed is the design and working principle of a welding monitoring system that can monitor the spectra of zinc and iron in the plasma generated during a welding process involving zinc-coated steel. The monitoring system is capable of monitoring multiple parameters, including spectral line intensity, electron temperature, and ratio of zinc and iron composition in the plasma. The results can then be used individually or in combination to predict resulting weld quality and generate appropriate feedback control signals.
