The Weld That Wasn’t: Using a Digital Microscope to Catch Aerospace Weld Defects Before They Fly
In aerospace manufacturing, the margin for error is not measured in millimeters. It is measured in lives. A weld that appears sound to the naked eye — and even to conventional inspection — can harbor subsurface porosity, incomplete fusion, or micro-cracking that will propagate under the cyclic stress of flight.
