ANALYSIS OF THE POSSIBILITIES OF USING THE SYNERGISTIC EFFECT TO IMPROVE THE PERFORMANCE OF HYBRID CUTTING AND WELDING TECHNOLOGIES

The article analyzes the positive effect of the synergetic effect on the hybrid processes of cutting and welding
that cause it. It is shown that the combined use of laser radiation and electric arc at a power ratio of 1:1 to 1:3
violates the additivity of the thermal effect on the product of the laser beam and arc plasma. This effect is most
clearly expressed in laser-plasma processes. The technological efficiency of the synergetic effect is directly proportional
to the power density of the laser radiation and consists in narrowing and increasing the depth of the
keyhole. This effect, in particular, manifests itself in the "binding" of the anode region of the arc to the plasma
torch is generated above the surface of the metal with a laser beam, and in accordance with the principle of
minimum Steenbeck (M. Steenbeck) it contributes to the reduction of the voltage at the arc gap.
