What is the focus of Article 4 in Section V?

Article 4 in Section V specifically focuses on the Ultrasonic Examination Methods of Welds. This section addresses the principles, techniques, and processes involved in using ultrasonic testing (UT) to evaluate the integrity and quality of welds in fixed equipment. Ultrasonic methods are essential for detecting internal flaws such as cracks, voids, and inclusions, which are critical for ensuring structural integrity and safety in various applications.

By concentrating on welds, Article 4 provides guidelines that help inspectors understand how to effectively apply ultrasonic techniques, the equipment required, and the interpretation of results. This ensures that any discontinuities within the welds can be identified and addressed appropriately, ultimately contributing to the reliability of the equipment being assessed. This focus is vital for professionals involved in quenching and ensuring compliance with industry standards, thereby enhancing overall safety and performance in fixed equipment.
