Investigations of the effect of the composition of gas mixtures on the temperature of the welding arc plasma

摘要

The temperature of the welding arc is the most important characteristic which determines the thermal effect on the processed material and the electrode. However, in the scientific and technical literature, there is insufficient information on the measurements of the temperature of the welding arc plasma in consumable electrode welding and on investigations of the effect of the composition of gas mixtures on the arc discharge temne.rature.
