Understanding Metal Fatigue in Welding and How to Prevent It

Metal fatigue is one of the most common but often overlooked problems in welding. It occurs when a material undergoes repeated cycles of stress, eventually leading to microscopic cracks and eventual failure. In welded joints, especially those exposed to vibration or load-bearing conditions, fatigue can compromise structural integrity if not addressed during design, material selection,…
