Computational Simulation and Distortion Validation from Conventional and Synergic Processes of Gas Metal Arc Welding (GMAW)
Abstract
The Welding, Processing, and Nondestructive Evaluation (NDE) Branch (Code 611) at the Naval Surface Warfare Center, Carderock Division (NSWCCD) was tasked with developing a digital twin of an experimental welding study to evaluate the residual stress and distortion of aluminum B2V.1 joints. The intent of the study was to validate the computational welding model, developed using a welding-based finite element analysis (FEA) software called SYSWELD, through the comparison of predicted and measured distortion values. However, the previous study that provided the experimental basis of this work did not include all of the information necessary for model validation, and the large number of assumptions made in the model, which resulted in inaccurate predictions. This study provides an example of the limitation of computational modeling when there are significant gaps in the information reported from experimental studies. A significant finding of this report is the recommendations for future experimental welding studies as well as improvements that can be made for future modeling efforts.
