Continuous monitoring of welded structure production is important to provide under conditions of robotic welding. As for MIG/MAG welding the preference should be given to control of electric parameters of arc, which generalize the conditions of technological process during 1 s. A complex evaluation of the electric parameters can be carried out in «arc current–arc voltage» area. The conclusions on presence of the disturbances should be made using coefficients of Haar wavelet decomposition. 5 Ref., 1 Table, 2 Figures.
