Abstract

In the active control of metal transfer of modified pulsed current gas metal arc welding (GMAW) through proper phase matching of the detaching electromagnetic force and the downward momentum of the droplets, one drop detachment per pulse (ODDPP) mode can be achieved reliably at a pulse current lower than the critical transition value. An analytical model is developed to analyse the droplet oscillation and detachment process and the effect of pulse parameters on the dynamic behaviour of metal transfer in active control of metal transfer of modified pulsed current GMAW. The model lays the foundation of optimum selection of welding process parameters in achieving the metal transfer mode of ODDPP in the active control of metal transfer during modified pulsed GMAW.
