Abstract
Способ многодуговой сварки или навлавки в защитных газах, при котором процесс ведут сочетанием плавящегося и неплавящегося электродов от источников питания переменного тока, отличающийся тем, что вначале ведут подбор источника для неплавящегося электрода, имеющего внешнюю круто падающую характеристику с большим напряжением холостого хода, затем для плавящегося электрода, имеющего полого падающую (жесткую) характеристику с низким напряжением холостого хода, электрически их соединяют так, что фаза напряжения на плавящемся электроде отстает от фазы напряжения на неплавящемся электроде, подают напряжение на электроды для возбуждения дуг, при взаимодействии которых в общем плавильном пространстве на плавящемся электроде формируются импульсы тока обратной полярности с частотой, равной половине частоты питающей сети, которые и осуществляют расплавление электродного металла и формирование сварного шва.A method of multi-arc welding or shielding in shielding gases, in which the process is carried out by a combination of a melting and non-consumable electrodes from AC power sources, characterized in that at first they select a source for a non-consumable electrode having an external steeply falling characteristic with a high open-circuit voltage, then for a melting an electrode having a hollow incident (hard) characteristic with a low open circuit voltage, they are electrically connected so that the voltage phase on the melting electrode from it disappears from the phase of the voltage on the non-consumable electrode, voltage is applied to the electrodes to excite arcs, during the interaction of which in the common melting space on the consumable electrode current pulses of reverse polarity are formed with a frequency equal to half the frequency of the supply network, which melt the electrode metal and form the weld .
