Abstract

fetched live from OpenAlex

A laser ultrasonic system has been installed on a seamless tubing production line at The Timken Company and is being used to measure on-line the wall thickness of tubes during processing. The seamless process consists essentially in forcing a mandrel through a hot cylindrical billet in rotation and results in wall thickness variations that should be minimized and controlled to respect specifications. The system includes a Q-switched Nd-YAG laser for the generation of ultrasound by ablation, a long pulse very stable Nd-YAG laser for detection coupled to a confocal Fabry–Perot interferometer. The lasers, data acquisition, and processing units are housed in a cabin off-line and connected to a front coupling head located over the passing tube by optical fibers. The system also includes a fiber-coupled pyrometer to measure tube temperature profile and two fiber-coupled optical velocimeters to measure the coordinates at the probing location on the surface of the passing, rotating hot tube. During the presentation further details of the system will be disclosed, as well as typical results and examples of its diagnostic capability.

Full frame distilled prediction

Teacher imitation

Not 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.
