Abstract
The excellent pseudoelasticity, shape memory and biocompatibility of Nitinol has made it a leading candidate for various applications, including aerospace, micro-electronics and medical devices. Challenges associated with the welding Nitinol need to be resolved before its full potential in practical applications can be attained. The current study details the effects of process parameters on the mechanical and pseudoelastic properties of Ni-rich pulsed Nd:YAG laser welded Nitinol. The weld strength, pseudoelastic and cyclic loading properties for varying welding parameters are compared to those of the base metal. Furthermore, fracture surfaces have been analysed and detailed. Results show that process parameters greatly influence the mechanical performance and fracture mode of weldments.

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
