<h2>Purpose</h2>
|
|||
|
|
<p>This protocol enables first-line supervisors to verify thermal compatibility of material joins before fabrication begins. Used on active sites in Mount Joy industrial corridor, validated against NIST reference standards.</p>
|
|||
|
|
<p><strong>Objective:</strong> Prevent catastrophic joint failure through pre-emptive measurement and gap specification.</p>

<h4>⚠ Critical Failure Points Observed in Field</h4>

<p><strong>Case 001:</strong> Steel-aluminum truss joint, La Grange greenhouse dome (2025-03). Gap omitted entirely. Failed at 147°C differential. Cost: $4.2M replacement.</p>
|
|||
|
|
<p><strong>Case 002:</strong> Titanium-copper heat exchanger, Mount Joy pilot plant (2025-09). Gap undersized by 3.2mm. Micro-fracture network detected at 89% design temp.</p>
|
