The paper presents the main parameters of fusion welding and their Off - line analysis of Polyethylene high-density PE-HD pipes. By direct measurements of voltage and current at the coupler, inductive and the resistant character changes in amplitude modulation waveforms of the measured signal are observed. In early measuring device analyzes the scanned parameters with certain types of fittings and compares them with the tested and measured parameters is done by welding machines. There can be seen the time delay or -dead time- when the system analyzes the parameters and dimensioned regulatory function of the system.
