Description
Technical Field
The invention relates to the field of laser filler wire welding processes, in particular to a high-quality laser filler wire welding process for an aluminum alloy skin-stringer structure.
Background
The aluminum alloy skin-truss type structure has the characteristics of light weight and high strength, and is widely applied to arc-shaped wall plate structures in the field of aerospace. Taking a wall plate of a storage tank barrel section as an example, the height of the reinforcing rib is within 10mm at present, and the problems of serious material waste, long processing period and the like exist by adopting a method of forming after integral machine milling. Especially for ribs with large height-thickness ratio, instability is easy to occur in the forming process. If the skin-stringer welding structure is adopted to replace an integral machine-milled wallboard, a large amount of material waste can be reduced, and the method has the advantages of low cost, high efficiency and the like. The skin is only required to be welded with the stringer after roll bending forming to form a wallboard structure, so that the difficulty of integral forming of the high-rib wallboard is avoided.
The welding of the skin-stringer structural panels generally requires the interface of the stringers to be welded through, so that the welding difficulty gradually increases as the thickness of the stringers increases. At present, the welding method for the skin-stringer structure mainly has two forms, one is that the stringer is penetrated from the back of the skin, and the single-side welding and double-side forming are carried out; one is double-beam laser synchronous welding on both sides of the stringer. For penetration welding (CN111673219A) with the back of the skin, the welding thickness is limited to the thickness of the skin, the penetration depth is too deep, aluminum alloy with the thickness of the skin exceeding 5mm is not suitable, and the appearance of the skin is affected. The double-side laser synchronous welding process mainly has the problems of unstable welding wire fusion, overproof aluminum alloy welding air holes and the like. For unstable welding wire fusion, patent CN111745296A, the skin boss presetting method and the welding process thereof proposed replace wire feeding in the welding process. The method increases the processing difficulty of the skin part, has high requirement on the processing precision of the stringer mounting groove, and can generate deformation when the skin is rolled and bent to influence the mounting precision of the stringer. For aluminum alloy laser welding, as the keyhole is unstable and is easy to form a process air hole, no good solution is provided for air hole control of aluminum alloy skin-stringer laser welding at present.
