Abstract
Considered is the effect of characteristics of a gas atmosphere on the process of contraction of the welding arc in inert gases. Calculations have been made, showing that the degree of contraction of the arc discharge depends upon the thermal-physical characteristics of the gas atmosphere and electron-atom collision processes. Impact of the Ramsauer effect on the arc discharge contraction characteristics has been established.
Keywords: contraction, inert gas, welding arc, Ramsauer effect
