Abstract
Способ электронно-лучевой сварки с контролем удельной мощности и тока фокусировки электронного луча, отличающийся тем, что из спектра колебаний вторичного тока в диапазоне частот 5-125 кГц выделяют сигнал переменной составляющей, включающей диапазон частот, содержащий «пик» спектральной плотности, который подвергают статистической обработке путем построения эмпирической плотности распределения указанного сигнала в амплитудном диапазоне, затем в зависимости от измеренных величин параметров эмпирической плотности распределения, например таких, как дисперсия, среднеквадратичное отклонение, модальное значение эмпирической плотности распределения или отношение значения плотности распределения к среднеквадратичному отклонению или к дисперсии, а также от внешнего вида эмпирической плотности распределения задают ток фокусировки, соответствующий максимальной удельной мощности электронного луча.A method of electron beam welding with control of the specific power and focusing current of an electron beam, characterized in that a variable component signal including a frequency range containing a "peak" spectral density is extracted from the secondary current oscillation spectrum in the frequency range 5-125 kHz, which is subjected to statistical processing by constructing an empirical distribution density of the specified signal in the amplitude range, then, depending on the measured values of the parameters of the empirical distribution density, for example measures such as the variance, the standard deviation, the empirical value of the modal density or the distribution ratio of the density distribution to the standard deviation or variance as well as the appearance of the empirical distribution density set focus current corresponding to a maximum power density of the electron beam.
