Abstract
Deterministic-statistical mathematical model of weld shape was the basis to develop a nomogram, which allows determination of basic parameters of arc welding in a mixture of Ar + 25 % CO2 of a square-butt joint by the specified dimensions of the weld (penetration depth, reinforcement height and weld width), taking into account the size of the gap in the butt, optimization of the mode by weld dimensions or, vise versa, determination of weld dimensions with the known welding mode.
Keywords: arc welding, Ar + 25 % CO2 mixture, consumable electrode, butt joint, gap, welding mode, nomogram, optimization of weld dimensions
