Abstract
Magnesium AZ31 sheets have been lap welded with magnetic pulse welding using H shaped symmetric coils connected to a Pulsar MPW-25 capacitor bank. The joints displayed an increasing trend in strength with discharge energy. The weld morphology consisted of twin bond zones separated by an unbonded centre zone. Metallographic examination of the unbonded centre zone revealed anisotropic deformation and a lack cleaning from the interface. This zone forms as a result of normal impact in the initial stage of collision. Transmission electron microscopy of the bond zone revealed a continuous interface having an 8–25 μm thick interlayer with dislocation cell structure and distinct boundaries with adjacent material. The interlayer may have formed in a semisolid state at elevated temperature. The interlayer corresponds to a ductile fracture surface and is responsible for the joint's high strength. Nanoscale grains were found beside the interlayer as well as larger, highly elongated grains.

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
