What testing method is used to assess fusion welds?

The appropriate method to assess fusion welds involves evaluating the integrity and quality of the weld. Radiographic testing is commonly used for this purpose as it provides a visual representation of the internal structure of a weld through the use of X-rays or gamma rays. This method can detect flaws such as lack of fusion, porosity, and inclusions, which are critical in assessing weld quality.

Pressure testing, while useful for testing the leak-tightness of pipes and vessels, does not focus on the internal characteristics of welds themselves. Magnetic Particle testing and Acoustic Emission testing have specific applications, such as detecting surface-breaking defects or monitoring the structural integrity of a system during operation, but again are not specifically tailored for assessing the overall quality of fusion welds.

Therefore, the chosen method for evaluating fusion welds effectively demonstrates understanding of how to ensure the safety and reliability of welded structures.
