Abstract
Dependence of weld shape on gap value in consumable electrode arc welding in Ar + 25 % CO2 mixture of a square butt joint was established and a deterministic-statistical model of weld shape with allowance for a gap effect was developed. The developed model is recommended for use in the design of software of the system of adaptive control of arc welding of butt joints with a non-stable gap.
Keywords: arc welding, consumable electrode, shielding mixture, square butt joint, gap, weld sizes, mathematical model
