Abstract
The Lean Six Sigma (LSS) framework is a strategic approach to managing waste, reducing inefficiencies, and optimizing manufacturing processes, such as those in welding. Its effectiveness lies in its ability to focus on minimizing waste and precisely directing processes. As industrialization progresses, it often leads to the depletion of natural resources such as water and land. Many welding industries have yet to fully implement effective waste control and process regulation strategies. This review explores how the LSS methodology can address and mitigate defects in industrial welding processes. Central to LSS is the DMAIC principle (Define, Measure, Analyze, Improve, and Control), which transforms problem-solving into a structured process with specific milestones to track progress. DMAIC has been widely applied in research for optimizing welding processes. This review examines how the LSS framework has been applied to welding processes, the improvements observed, and provides guidance on advancing sustainable welding practices.

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
