1. Estudo da influência dos parâmetros no processo de soldagem GMAW - arco pulsado
Pulsed gas metal arc welding describes the metal transfer mode involving oscillation (pulsing) of the welding current from a high pulse current in which level drop growth, necking of wire tip and detachment occur, and a low background current, which is applied to maintain the arc. The advantages of the process are: metal transfer without spatter formation an

2. Fenômenos de instabilidade do arco na soldagem GMAW com gases de baixo potencial de oxidação
The arc welding process with continuous wire and gas protection (GMAW) is currently one of the most important metal joining process. This process has passed through a constant evolution with the introduction of power supplies with electronic control, and the use of techniques to control metal transfer, its operational stability and weld bead formation.
