METHOD FOR EVALUATION OF PARAMETERS OF MOTION OF WELDING ARC IN ARC SIMULATION SYSTEMS

摘要

Method for evaluation of parameters of motion of welding arc in arc simulation systems at which rate of welding is determined through measurement of length of pass of welding arc at given time interval at its displacement along welded sample arranged as uniform electro-conductive plate with constant at whole length area of cross section, this is with both ends connected to one of poles of source of welding current, at that one measures current , that flows in external welding circuit and current , that flows through section of welded sample with length from point of arc to end of sample in direction of which arc moves, and current coordinate Xt of arc point one accesses as product of value of length of sampleby ratio of value of current to value of current . By the ratio one determines, as average arithmetical value of group of readings for currents || and || for time interval, values of modules of currents || and ||, flowing in welded sample in opposite with respect to spot of arc directions.
