Abstract: In this paper the essential relations between the optical emission and the physical properties during the are welding process are investigated in both the character of spectrum and the practical application aspects. Some examples we have made in are provided as well, it is shown that the spectral information and spectroscopic diagnostics are of remarkable potentialities to the measurement and control of welding process.

Key words: Control, Measurement, Spectral information, Welding arc
