| Abstract: | Interdependence of parameters in the whole dynamic GMAW system with short circuit transfer was researched. Dynamic model of the whole GMAW system with short circuit transfer was built by expanding the sub-model about welding circuit of short - circuit transfer. Relationship between welding current and wire-melting rate was discussed, and the influence of wire - melting rate on wire extension and height of liquid bridge was analyzed as well. |
