EFFECT OF PRE- AND POST-WELD SHOT PEENING ON THE MECHANICAL & TRIBOLOGICAL PROPERTIES OF TIG WELDED ALUMINUM 6061-T6 ALLOY
Bibliographic record
Abstract
In this paper, the effects of shot peening on the performance of TIG welded 6061-T6 Al alloy are investigated. Six different scenarios are evaluated utilizing two levels of high/low shot peening intensities. The hardness profiles demonstrate a “W” shaped distribution, with low hardness values in heat affected zone, implying coarsening of precipitates. Except for ductility, the results indicate that all shot peening scenarios enhance the tensile properties of the welded specimens with respect to the unpeened control, with enhancements ranging from approximately 3 to 35%. Pre-weld low intensity shot peening results in the highest increase of tensile strength. The coefficient of friction ranges from approximately 0.4 to 0.9 compared to the unpeened control with a coefficient of approximately 0.6.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
