Abstract
Effectiveness of application of a two-channel system of automatic stabilization in consumable-electrode pulsed-arc welding of aluminium alloys under the impact of disturbing factors has been established experimentally. It is shown that the mechanical properties of butt-welded Joints of AMg6 alloy produced by pulsed-arc welding deteriorate with increase of electrode wire extension and lowering of the mains voltage. Use of a two-channel system of automatic stabilization of pulsed-arc process allows ensuring the mechanical properties of butt-welded Joints on the level of those obtained in optimum modes without disturbances.
Keywords: pulsed-arc welding, consumable electrode, alu¬minium alloys, automatic stabilization, two-channel system, disturbing factors, average value of welding current, average value of arc voltage, geometrical dimensions of welds, defects, mechanical properties
