Dual-beam welding of aluminum alloy is also a way to eliminate air holes. A 6 kW continuous fiber laser was used to perform dual-beam butt welding of 5052 aluminum alloy. The two-beam parallel and serial welding modes and welding at different welding speeds were studied. The study of seam morphology and structure found that there are large holes in the welds welded in parallel with dual beams, and welding aluminum alloys in series can obtain good weld formation without porosity.
