Abstract
Способ сварки неплавящимся электродом в защитных газах, при котором дугу прямой полярности, горящую между неплавящимся электродом и изделием, питают импульсами тока, обеспечивающими сквозное проплавление металла при непрерывном движении сварочной головки, отличающийся тем, что применяют форму импульсов тока, близкую к прямоугольной, а длительность импульсов тока ограничивают величиной, обеспечивающей горение дуги во время импульса тока в динамическом режиме, причем амплитуду импульсов тока изменяют установочно изменением напряжения источника питания, частоту следования импульсов тока плавно, а длительность импульсов тока ступенчато - в обратно-пропорциональной зависимости от отклонения среднего значения напряжения на дуге от заданного, при изменении скрытой составляющей длины дуги.A method of welding with a non-consumable electrode in shielding gases, in which an arc of direct polarity, burning between the non-consumable electrode and the workpiece, is fed with current pulses providing through-penetration of the metal during continuous movement of the welding head, characterized in that they use a current pulse shape that is close to rectangular, and the duration current pulses are limited to a value that ensures arc burning during a current pulse in dynamic mode, and the amplitude of the current pulses is changed by setting the voltage power source current pulse repetition frequency continuously, and the current pulse width in steps - in reverse proportion to the average voltage value of the deviation from a predetermined arc, when changing the hidden part of the arc length.
