XIRIS Blog Porosity in Welding: Causes, Types, and How to Detect It

What is porosity in welding? Porosity in welding refers to small cavities or holes that form within the weld metal due to trapped gas as the metal solidifies. These gas pockets compromise the weld's structural integrity, potentially leading to weaker joints, increased susceptibility to corrosion, and even failure under stress. Understanding and addressing porosity is crucial across all welding applications to maintain high-quality and durable welds.
