CO2 welding short-circuit electromagnetic force and surface tension of self-balanced approach to transition


Established in the necking process liquid bridge surface morphology changes of liquid bridge simplified model of liquid bridge in different forms by the surface tension of the nature under the analysis showed that the surface tension of the liquid bridge depends on the nature of the role of liquid height and liquid bridge bridge necking radius. Taking into account the fluctuations of the bath liquid bridge height and radius of necking factors, according to short-circuit resistance change rate reaches a certain threshold to achieve entirely on surface tension of liquid bridge continued to shrink until the explosive method of breaking the surface tension of the transition there must be stability of welding issues. (2) According to the necking level (liquid bridge resistance) automatically change to different external characteristics of short-circuit current adaptive control, both to prevent the post-necking over-concentration liquid bridge energy and reduce the splash, but also realized the automatic droplet balanced under the electromagnetic force and surface tension of the transition, thus ensuring the stability of the welding process. Welding test results show that this method has less splash, smooth weld appearance and welding process stability and so on. (3) With the development of inverter technology and the improvement of the frequency inverter welding power source to further improve the dynamic characteristics of this method will show a greater superiority.
