Testing device for checking jointed connections on components for internal defects/surface defects uses thermal imaging

摘要

Aligned at a component's surface (7), a thermal-imaging camera (9) detects distortions in a component's (8) surface temperature field that arise through cooling the component off. Linked to the thermal-imaging camera, a computer (10) evaluates images. Filled with compressed air from a compressed air supply (1) via an inlet valve (2), a compressed air reservoir (3) links to a nozzle (5).
