# The lab that proves the weld. > The AMR metallurgical lab in Hawthorne, California: sectioning, metallography, macro inspection to ISO 13919-1, dye-penetrant NDT to ASTM E165, and traceable weld records organized to ISO 15614-11, next to the cell that made the weld. URL: https://advancedmetalresearch.com/metallurgy Metallurgical lab · Hawthorne R&D lab Hawthorne, California Sectioning, inspection, and evidence Every procedure we develop is sectioned, etched, and inspected in our metallurgical lab, in the same building as the cell that welded it. You receive macro sections, inspection data, and a written procedure.

Outcome: **faster weld qualification.** Procedures are developed and tested at AMR, so the qualification evidence comes from the same lab that ran the weld. 1. **Section.** The weld coupon is cut, mounted, ground, and polished into a traceable cross-section. 2. **Etch and inspect.** Penetration and defects on the etched cross-section are evaluated against the acceptance standard. 3. **Test the surface.** Dye-penetrant testing finds surface-breaking cracks without cutting the part. 4. **Record.** Each sample gets a traveler, a machine-readable analysis file, and a report.

Predicts · pool temperature and shape Services · WPS PQR WPQ ## Name the code you need to meet. We write, test, and qualify the procedure. Welding procedure development, qualification-support evidence, and metallurgical testing, proven in our lab with macro inspection to ISO 13919-1 and dye-penetrant testing to ASTM E165. - **Procedure qualification:** Welding procedure development and qualification-support evidence for WPS, PQR, and WPQ. - **Metallurgical testing:** Sectioning, mounting, polishing, etching, macro inspection, and dye-penetrant NDT. - **Metallurgy research:** Process development, destructive test planning, material characterization, and weld-quality iteration, with automated experiment records. - **Modeling:** Applied mathematical modeling and weld-pool simulation, so a procedure is tuned before the first coupon is welded.

The lab sits next to the cell. Welds from every procedure we develop are sectioned and inspected here, and the result informs the next weld, the next fixture, and the next procedure. War Machine and the lab share one data record: the cell sees the part, measures the setup, welds the assembly, and inspects the result, and the lab closes the loop with the cross-section. The same evidence trail supports qualification, quality review, and procedure development.
