The influences of pulse parameters, arc voltage and welding speed on the characteristics of weld beads deposited on C-Mn steel plate by flux cored GMAW process have been studied. The pulse parameters are found to affect the microstructure and porosity content of weld bead and the width of HAZ. The arc voltage, affecting the <I>l</I><SUB>p</SUB>, and <I>l</I><SUB>b</SUB>, also found to influence the characteristics of weld bead significantly. The porosity content of weld bead and the width and hardness of HAZ are found to have a significant correlationship with a factor, defined as a function of <I>l</I><SUB>p</SUB>, <I>l</I><SUB>b</SUB>, <I>f</I> and <I>t</I><SUB>b</SUB>. The influence of welding speed has been found of usual nature. It is marked that a right selection of pulse parameters can improve the weld quality over that observed in case of continuous current GMAW.
