In-situ Defect Detection
In-situ defect detection is automated monitoring of the build process that detects cracks, porosity, or lack of fusion during layer buildup. This enables immediate process correction.
Physical-Chemical Mechanism of Action
In-situ defect detection uses cameras or tomography systems to monitor the build process in real time. These systems analyze the material structure and identify anomalies such as cracks, pores, or missing bonds.
Metallurgical Relevance & Welding Risks
Detecting defects during the welding process enables quick reaction and reduction of errors. Without such monitoring, undetected defects can lead to later cracks or failures, compromising the safety and lifespan of the components.
Workshop Practice & Action Instructions
To successfully use in-situ defect detection, cameras or tomography systems must be properly installed and calibrated. Monitoring should be continuous, and detected defects should be immediately linked to process corrections. This can be achieved, for example, by adjusting welding parameters or by removing and rebuilding faulty layers.
