Abstract
The arc rotation mechanism system can be used to obtain the flat and broad weld bead due to the centrifugal force of the rotating arc at welding. In this investigation an arc rotation mechanism is developed and four input process parameters such as arc rotational speed , ratio of wire feed rate to travel speed, wire feed rate and eccentricity are considered. The experiments were conducted on square butt joint plate of 5083 H111 aluminum alloy using full factorial design of experiments. The mathematical models for penetration and convexity are developed using multiple nonlinear regression analysis and are checked for their adequacy. The confirmation experiments were conducted to verify the models .The mean analysis for penetration and convexity is done at all three levels of input process parameters. It is observed from the investigation that eccentricity has maximum effect on convexity followed by arc rotational speed, ratio of wire feed rate to travel speed and wire feed rate whereas wire feed rate have relative maximum effects on penetration. Key words: Arc rotation mechanism, arc rotational speed, eccentricity, full factorial, square butt joint, aluminum alloy.

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 it
