Effect of laser on double-arc physical characteristics in pulsed laser-induced double-TIG welding [PDF]
The International Journal of Advanced Manufacturing Technology, 2021 Abstract In order to improve the energy utilization efficiency of double-TIG arc, based on the synchronous induction of pulsed laser to double-arc, the coupling-enhanced discharge phenomenon between double-arc is studied in this paper. The energy utilization efficiency of pulsed laser induced double-arc is quantitatively analyzed.
