Abstract
Radial and axial distribution of gas-dynamic characteristics of plasma flows in welding arcs has been studied. Arc column shape was approximated in the form of a truncated cone of a height, equal to arc length, and radii of upper and lower bases determined as corresponding sizes of a luminous region on the arc filming frames. Comparison of calculated data with available experimental data showed a satisfactory correlation of results obtained for the rate and pressure of plasma flows in definite welding arcs.
Keywords: welding arc, plasma flows, gas-dynamic pressure, magnetostatic pressure, arc constriction, asymmetric current, penetration shape, aluminium alloys, welding technology
