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.
