In this work, the heat input of the welding arc, calculated from the measured values for voltage and current, is compared to the heat gained by the weldment for pulsed and nonpulsed current welding. The effects of shielding gas composition, arc length, weld geometry and weld position on heat transfer are examined. Methods for calculating the heat received by the weld during pulsed current welding are discussedread more

Effect of Pulse Parameters on Weld Quality in Pulsed Gas Metal Arc Welding: A Review
Kamal Pal,Surjya K. Pal +1 more
TL;DR: P-GMAW as discussed by the authors uses a higher peak current to allow one molten droplet per pulse, and a lower background current to maintain the arc stability, which can reduce the weld service life in continuous mode gas metal arc welding.
