What is Concave root intermittent weld defect? how to determine

Concave root intermittent weld is a welding defect characterized by an irregular, concave profile at the root of a weld joint, with intermittent fusion between the weld metal and the base metal. This defect can compromise the strength, integrity, and gas-tightness of the weld joint, particularly in applications where weld quality is critical. Example: Welding of Pressure Vessels Consider the […]
