The spectral method was used to investigate the real GTA welding arc burning between a non-consumable tungsten electrode and a consumable titanium and non-consumable copper water-cooled anodes. Experimental data were obtained on distribution of temperature in the arc column along the arc radius near the anode. It is shown that axial distribution of temperature in the arc column depends upon the state of the anode. In a region adjoining the anode the arc temperature is higher in the vicinity of the consumable anode.
Keywords: welding arc, spectrum, arc temperature, titanium anode, non-consumable anode, tungsten electrode
