What is a common method used for testing weld integrity in a boiler?

• A. Visual inspection
• B. Non-destructive testing (NDT) methods
• C. Pressure testing
• D. Ultrasonic cleaning

Answer: (B)

Non-destructive testing (NDT) methods are crucial for assessing weld integrity without causing any damage to the welds or the base materials. These methods allow for the detection of defects such as cracks, porosity, or incomplete fusion within the welds, which are vital for ensuring the reliability and safety of boiler operations. NDT techniques can include ultrasonic testing, radiographic testing, magnetic particle testing, and dye penetration testing, each serving a specific need in the evaluation process. The effectiveness of NDT lies in its ability to provide thorough inspections while preserving the integrity of the components being tested, which is essential in high-stress environments like boilers. This approach helps maintain high safety standards and prolongs the operational lifespan of the boiler. Meanwhile, other methods like visual inspection, pressure testing, and ultrasonic cleaning serve different purposes that do not specifically address the comprehensive evaluation of weld integrity as effectively as NDT methods do.
