Finite Element Simulation to Optimize the Mechanical Properties and Deformation of the Bevel Joint of 9.25 mm Thick Aluminum 6061-T6 with only One Pass
Bibliographic record
Abstract
In industrial settings, it is customary to employ at least a three-passes welding for 9.525 mm-thick welded samples, which results in increased angular distortion and longitudinal/transversal deformation. This study outlines the optimized welding parameters for a butt-welded joint V groove with a 60-degree bevel angle and a 2.5 mm root face, utilizing a single pass, on a 9.525 mm thick sample. The present investigation involved the development of a 3D computational model to examine the thermal characteristics and distortion distribution during the process of gas metal arc welding of the aluminium alloy 6061-T6. The present paper employed the Taguchi methodology to compute the thermal behaviour technique using orthogonal arrays, a well-established Design of Experiments (DOE) approach for finite element analysis (FEA). Additionally, an artificial neural network (ANN) model was employed to forecast distortion and stress. The study produced 3D surface graphs and contour plots to clarify the correlation between welding parameters, stress, and distortion. Following the determination of optimized parameters through finite element analysis (FEA), experimental tests were conducted to compare and validate the FEA outcomes. The present investigation has employed welding parameters, namely arc voltage (v), arc travel speed (mm/s), current (A), gun angle (degree), distance between the nozzle and weld (mm), and root gap (mm).

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
