Research on the Structural Model of Welding Process Specifications for Aviation Products Based on Trade-Off Design
Year: 2025
Type: article
Abstract: Aviation products demand exceptionally high safety standards, where welding quality directly impacts structural integrity and flight safety. Welded joints must possess high strength and fatigue resistance. Since the welding process cannot be fully inspected and is classified as a special process, its manufacturing and production procedures require strict control, making the completeness of process specifications particularly crucial. Currently, the formulation of welding process specifications primarily relies on the production experience of process designers, with excessive focus on equipment processing parameters. This often leads to unstable product quality during production and fails to provide valuable references for aircraft structural designers. To enhance the performance, stability, and cost-effectiveness of Aviation welded products, this paper thoroughly considers the design requirements for welded products. It analyzes the full spectrum of elements within process specifications based on trade-off design. A structural model for welding process specifications is proposed, and a knowledge-driven methodology for standard verification and determining critical indicators is investigated. Using a laser welding production process as a case study, the structural model for Aviation product welding process specifications is validated.
