Abstract
Formulae to determine temperature of the welding arc plasma as a function of pressure in the plasma have been derived using the Steenbeck principle of the arc minimum. It is shown that the Khrenov’s formula becomes precise at a very high pressure, while at low pressure the formula, defined more precisely, is valid, giving the decrease in temperature and increase in degree of ionisation of plasma with pressure reduction in the arc plasma.
Keywords: welding arc, temperature of plasma, pressure in plasma, calculation
