Brazed Seam Pore Freedom
Solder joint porosity-free means no gas inclusions or voids are present in the solder joint. This ensures a robust and defect-free connection.
Physical-Chemical Mechanism of Action
Brazed seam freedom from porosity results from complete wetting of the metal by the braze material. Gases, such as oxygen or hydrogen, are expelled during brazing, preventing voids from forming.
Metallurgical Relevance & Welding Risks
Porosity in the brazed seam can lead to fracture, corrosion, and reduced mechanical strength. These can significantly shorten the service life of the part.
Workshop Practice & Action Guidelines
To ensure brazed seam freedom from porosity, it is important to bring the braze material to the correct temperature level and slowly cool the joint. Use enough braze material and ensure a clean metal edge. For complex parts, it helps to divide the brazing process into several steps.
