A comprehensive model for miscellaneous mass transfer mode in gas metal arc welding

Welding is an operation that aims to join two or more pieces, holding that on combination of these parts there will has no discontinuity of physical, chemical and metallurgical properties for its use and performance. This work deals with the modeling of this system. For this, two models are presented: one represents the dynamic of drop formation on electrode tip and the second model represents mass transfer dynamic when a short circuit occurs.
