The influence of plasma arc composite laser welding parameters on aluminum alloy weld seam weld penetration

Abstract

In laser and plasma arc compound heat source welding technology, we collected a series of comparative data for a full range of analyses. We proceeded with an in-depth discussion of these two welding technologies in terms of the weld penetration, the melted width, the shape and size of the weld, laser power, heat source spacing, and welding speed. After research, we found that during laser-arc hybrid welding, weld penetration is very sensitive to laser power and welding speed but relatively less sensitive to heat source spacing and welding speed.
