Sur la QRG (voir code Q) comme on dit dans notre jargon. Des rendez vous en fréquence (SKED) sont programmés les lundis soirs sur notre réseau de relais transparents (en VHF / UHF) ou en HF (7 074 Mhz et 3 674Mhz) et constituent le moment privilégié pour échanger entre nous : nous l'appelons le QSO de section.

Quicksurface cracks are a type of fracture that can occur in materials, particularly in welds, castings, and other fabricated components. Understanding the causes, characteristics, and types of Quicksurface cracks is essential for detection, prevention, and mitigation. By implementing a combination of NDT, visual inspection, material selection, design optimization, and quality control measures, engineers and manufacturers can reduce the risk of Quicksurface cracks and ensure the reliability and integrity of their products.
A Quicksurface Crack, also known as a Quicksurface or surface crack, is a type of fracture that occurs in materials, particularly in welds, castings, and other fabricated components. It is characterized by a sudden and rapid propagation of a crack along the surface of the material, often with little or no warning. quicksurface crack
