Известен способ ультразвуковой сварки, при котором на соедин емые издели  воздействуют одновременно двум  инструментами, колебани  которых имеют равные частоты и сдвинуты по фазе.The known method of ultrasonic welding, in which the connected products are affected simultaneously by two instruments, the oscillations of which have equal frequencies and are shifted in phase.

Однако такой способ сварки не обеспечивает необходимого качества сварного соединени .However, this welding method does not provide the required quality of the welded joint.

По предлагаемому способу дл  повышени  качества сварного соединени  пропесс ведут при угле сдвига фаз, равном  /2. При этом обеспечиваетс  непрерывность протекани  сварочного процесса за счет циклических колебаний инструмента.According to the proposed method, to improve the quality of a welded joint, the process is carried out at a phase angle equal to / 2. This ensures the continuity of the welding process due to cyclic oscillations of the tool.

На чертеже показаны эпюры скоростей колебаний инструментов, когда излучатели сварочных головок возбуждаютс  двум  напр жени ми одинаковой частоты, сдвинутыми поThe drawing shows plots of the oscillation speeds of the instruments when the emitters of the welding heads are excited by two voltages of the same frequency shifted along

В тот момент, когда скорость Vi инструмента через - единиц времени равна О (точка Л),At that moment, when the speed Vi of the instrument in - time units is equal to O (point L),

скорость Vz второго инструмента максимальна (точка Б). Следовательно, относительна  скорость свариваемых деталей, когда инструменты наход тс  в точках А, Б, В, Г и т. д., не равна 0. Интерес представл ют точки Д и Е. В этих точках скорости инструментов равны. Поскольку ViT)V2D, но не равны О, на сварной шов действуют колебани  инструментов, направленные вдоль их осей, которые по направлению совпадают со сварочпым усилием. Зти колебани  создают дополнительное давление в зоне сварки к удельным давлени м, вызванным сварочным усилием. PI, несмотр  на то, что относительные перемещени  свариваемых материалов равны О, когда скорости инструментов V. равны, сварной шовthe speed Vz of the second tool is maximum (point B). Consequently, the relative speed of the parts to be welded, when the tools are located at points A, B, C, G, etc., is not equal to 0. Interesting are points D and E. At these points the speeds of the tools are equal. Since ViT) V2D, but not equal to O, oscillations of tools, directed along their axes, which in the direction coincide with the welding force, act on the weld. These vibrations create additional pressure in the welding zone to specific pressures caused by the welding force. PI, despite the fact that the relative displacements of the materials being welded are O, when the speeds of the tools V. are equal, the weld

Перемещение зоны сварки относительно свариваемого элемента вызывает на периферии сварного соединени  пластическую деформацию свариваемых материалов,moves relative to the elements to be welded. The movement of the welding zone relative to the element being welded causes plastic deformation of the materials being welded at the periphery of the welded joint.

обеспечива  при этом защиту сварного соединени , преп тству  прониковению кислорода в зону сварки, что и обеснечивает непрерывность процесса сварки и повыщение качества сварного соединени .while providing protection of the welded joint, preventing oxygen penetration into the welding zone, which ensures the continuity of the welding process and an increase in the quality of the welded joint.
