[0036] Welding droplet transition control equipment and control method based on ultra-audio pulse double tungsten pole coordination. The invention relates to a welding droplet transition control device and control method, in particular to a welding droplet based on ultra-audio pulse double tungsten pole coordination The transition control device and control method belong to the field of metal welding and additive manufacturing.
[0037] In the welding process, the thermal and force behavior of the droplet transfer has an important influence on the weld formation and welding quality. Generally speaking, a good form of droplet transfer is conducive to improving weld formation, reducing weld spatter and improving joint quality. In the existing MIG welding method, since the welding wire melting and transition mode is directly related to the current, it is difficult to independently control the welding wire melting speed and the droplet transition. For example, when...
