Welding inspection of pressure vessels is the process of evaluating welds to ensure they meet safety and quality standards. This inspection checks for defects such as cracks, porosity, and incomplete fusion that could compromise the vessel's integrity. Techniques like visual inspection, ultrasonic testing, and radiographic testing are commonly employed to assess the quality of the welds. Regular welding inspections are critical for the safe operation of pressure vessels in various industries, ensuring compliance with regulatory standards and preventing failures.
