Why the welding defects dangerous?

Welding defects are dangerous because they can compromise the structural integrity and safety of welded components, leading to potential failures during operation. These defects, such as cracks, porosity, or incomplete fusion, can result in catastrophic accidents, injuries, or loss of life, particularly in critical applications like construction, manufacturing, and aerospace. Additionally, they may lead to costly repairs and downtime, impacting overall project efficiency and safety. Ensuring high-quality welds is essential to maintain reliability and performance in welded structures.
