The weld morphologies, droplet transfer, and spatters of laser pulsed-arc hybrid welding were studied using high-speed photography, macro-metallograph, and welding electrical signal acquisition. Results show that laser pulsed-arc hybrid welding can improve the welding morphologies. The weld morphologies were improved. The welding current, the arc voltage, and the droplet transfer mode were changed significantly during the laser pulsed-arc hybrid welding. The liquid bridge formed between the droplet and the molten pool as well as the wire and the droplet explored under the action of excessive electromagnetic contraction force, and the droplets on the surface of molten pool exploded under the action of the arc force and expansion of gases, so the welding spatters were produced. Spatters are significantly reduced during laser pulsed-arc hybrid welding, mainly because the pulse arc reduces the short circuit transfer current and pool oscillations.
