Distortion analysis and optimization of grillage structure assembly process by finite element inherent strain method (FE-ISM)—part 2: post-weld flame straightening and experimental verification

Key Points

• Post-weld flame straightening significantly reduces welding deformation in grillage structures, enhancing their performance.
• The experimental verification of the inherent strain method confirms its accuracy in predicting deformation outcomes.
• Observational analysis using finite element methods assesses the assembly processes across various configurations.
• Highlights the necessity for effective post-weld treatments to ensure structural integrity in assembly processes.
