Influence Mechanism of the Heat Input on the Element Distribution and Mechanical Behavior of Beads Welded by Pulsed GMAW

Similarly well-formed welds can differ markedly in service performance, yet the metallurgical origin of this difference has rarely been quantified. Bead-on-plate welds were prepared on AA6061 with an ER4047 filler by pulsed gas metal arc welding (P-GMAW); with the pulse waveform kept constant, the base current was rais...
