摘要：
The realized researches followed the determining of mathematical models that allow the optimization of the welding process in order to obtain welded joints with certain values of the mechanical characteristics. Thus, there were established mathematical models of dependence of mechanical characteristics of welded joints (R-m, R-p02, Z, A, K-CV 20 degrees C) of each parameter of welding regime (I-w, U-w), and also, mathematical models that offer cumulative dependence of mechanical characteristics of both parameters of welding regime. The researches have been carried out using steel E 36-4 as base material and as filler material basic electrodes, type E7018 and the applied welding procedure was the process: shielded metal arc welding (SMAW).
