Investigation of Plasma and Metal Transfer Dynamic Behavior During Fiber Laser GMAW-P Hybrid Welding
The dynamic behavior, metal transfer mode, as well as the characteristics of electrical signals during the fiber laser with high power and the pulsed gas metal arc welding (GMAW-P) hybrid welding process are studied. The results show that the pure Ar gas can be used as the shielding gas in the fiber laser welding. The mixing of the GMAW-P arc with the fiber laser leads to the expansion of laser plasma and the shortening of arc length. The comparison results of the voltage probability density show that the dynamic load fluctuation of the laser-leading mode is much more violent than that of the arc-leading mode.
