Why the welding defects are hazadous?

Welding defects are hazardous because they can compromise the structural integrity of welded joints, leading to potential failures in critical applications such as bridges, pipelines, and pressure vessels. Defects like cracks, porosity, and incomplete fusion can create weak points that may fail under stress or environmental conditions. This not only poses safety risks to personnel but can also result in significant economic losses and damage to property. Moreover, undetected defects can lead to catastrophic accidents, making rigorous inspection and quality control essential in welding processes.
