Evaluation of dynamic defect detection in FSSW welded joints under fatigue tests

Procedia Engineering, 2010
AbstractThe present study aims to evaluate the dynamic defect monitoring technique (CVM–comparative monitoring vacuum) during fatigue tests in FSSW welded joints. This method is recent and has been applied to aeronautic industry. It works basically by pressure difference measurements between two positions, one firstly evacuated and another at ambient ...
