【 摘 要 】

The article presents the process of production of coated electrodes and their welding properties. The factors concerning the welding properties and the currently applied method of assessing are given. The methodology of the testing based on measuring and recording of instantaneous values of welding current and welding arc voltage is discussed. The article presents the application of Fast Fourier Transform (FFT) for the analysis of instantaneous values of welding current and welding arc voltage. The results of coated electrodes welding properties are compared. Finally the conclusions drawn from the research are presented.
