3-AI Evaluation Live Code Authority Teacher + Student AI TEKS §130.422 / §130.423 Mobile-First

3-AI Weld Evaluation Pipeline

Three independent AI models evaluate every weld. No single-model bias. Always graded against the CURRENT code edition.

1

Live Code Authority

Pulls the CURRENT edition of the applicable code (AWS D1.1:2020, ASME IX:2023, API 1104:2021, etc.) and retrieves exact acceptance criteria for the specific weld configuration.

2

Tri-Model Analysis

Three AI models evaluate independently: Model A (visual quality), Model B (code compliance), Model C (safety review). If they disagree, it's flagged for teacher review.

3

Resolution + Teaching

An adversarial resolution engine builds consensus, then generates teaching points, corrective actions, and next-step recommendations tailored to the student's level.

Built for CTE Programs

Features

📷

Photo Weld Evaluation

Snap a photo, enter your parameters. Get a code-compliant grade in seconds with detailed feedback on what to improve.

📋

WPS-First Teaching

Students learn to weld to procedure. Upload your WPS or enter specifics — the AI evaluates against YOUR procedure, not just visual appeal.

🤖

Teacher AI Assistant

Generate TEKS-aligned lesson plans, create quizzes, build rubrics, look up code requirements — all backed by 4DNT Intelligence OS.

📱

Student Study Buddy

Students get their own AI tutor. Explains grades, quizzes on knowledge, recommends settings. Won't give test answers — teaches instead.

📝

AI Test Generation

Generate quizzes from any lesson module. Multiple choice, true/false, weld identification, symbol ID. Auto-graded with answer keys.

📊

Progress Tracking

Track every student's progression through positions and processes. See who's ready to advance and who needs more practice time.
