Pulsed tungsten inert gas (TIG) welding is widely used in industry due to its superior properties, so the
measurement of arc temperature is important to analyse welding process. Arc image of spectral line in 794.8 nm
is captured by high speed camera; both the Abel inversion and the Fowler-Milne method are used to calculate
the temperature distribution of the pulsed TIG welding. Characteristic of transient variation in arc intensity and
temperature is analyzed. When the change of current happens, intensity and temperature of arc jump as well, it
costs several milliseconds. The further the axial position from the tungsten is, the greater the intensity jumps,
and the smaller the temperature changes.
