Fun Fact Friday: ASME NQA-1 Quality Assurance Program

Fun Fact Friday: ASME NQA-1 Quality Assurance Program

Encorus is proud to offer guaranteed reliability through our established American Society of Mechanical Engineers (ASME) Nuclear Quality Assurance Program (NQA-1).

Lindse Runge, one of Encorus’s Quality Assurance Technicians, gives some insight regarding what the NQA-1 Program is, what she does, and what type of clients would benefit from the program. NQA-1 is a nuclear quality assurance standard for nuclear facilities in the U.S. It relates to the design, construction and operation of such sites, and is a highly-regarded industry standard. ASME NQA-1 was created and is maintained by the American Society of Mechanical Engineers (ASME). This standard provides requirements and guidelines for the establishment and execution of quality assurance programs during siting, design, construction, operation and decommissioning of nuclear facilities. This standard reflects industry experience and current understanding of the quality assurance requirements necessary to achieve safe, reliable, and efficient utilization of nuclear energy, and management and processing of radioactive materials. The standard focuses on the achievement of results, emphasizes the role of the individual and line management in the achievement of quality, and fosters the application of these requirements in a manner consistent with the relative importance of the item or activity.

Lindse’s responsibilities include enforcing and implementing the requirements of Encorus’s QA program, developing / revising documents as required to comply with customer QA requirements and ASME NQA-1 requirements, reviewing customer purchase orders for QA requirements in order to develop plans to implement requirements throughout the project, reviewing Encorus purchase orders for QA requirements to ensure flow-down of customer requirements, participating in audits and surveys, and maintaining project files and documentation to ensure legibility, revision control, and traceability of records.

Encorus has a Quality Assurance Program that conforms to NQA-1 requirements to allow us to supply items and services to nuclear facilities. Clients that would benefit from an NQA-1 Program include the Department of Energy, Department of Defense, nuclear constructors, nuclear fabricators, and nuclear power plants.

If you think you would benefit from Encorus Group’s NQA-1 Program, please contact Quality Assurance Technician Lindse Runge at (716) 592-3980 ext 137 or lrunge@encorus.com.

Fun Fact Friday: The Differences Between Radiographic & Ultrasonic Weld Testing

Fun Fact Friday: The Differences Between Radiographic & Ultrasonic Weld Testing

Welds can be tested using three different methods: destructive, in which the weld is destroyed to examine the physical properties of the metal and components; mechanical, which is used to determine the properties of a metal under force; and non-destructive, in which the integrity of the weld can be determined without destroying the weld itself. The primary advantage of non-destructive examinations (NDE) is the ability to examine a component’s surface, sub-surface, and internal makeup for defects while keeping the weld intact. Its two most common types are radiographic testing and ultrasonic testing.

Radiographic Weld Testing

Also known as x-ray inspection, radiographic testing involves the use of commercial x-ray or gamma units to examine visible discontinuities on the interior of the weld, including:

– Cracks

– Scattered porosity

– Blowholes

– Inclusions

– Undercutting

The process is similar to that used to take x-rays of the human body. Gamma rays are passed through a tube onto photographic film to produce an image of internal components. As in the medical field, special expertise is required to perform radiographic weld testing and interpret the results. Due to its requirement for specific equipment, highly qualified personnel, and extensive safety precautions, its cost tends to run higher than other types of testing. However, radiographic testing is acknowledged as one of the most versatile and widely accepted forms of NDE, as it’s required to meet the welding codes and standards established by many relevant organizations, such as American Welding Society (AWS) and American Society of Mechanical Engineers (ASME).

Ultrasonic Weld Testing

Used to check for surface and sub-surface discontinuities, ultrasonic weld testing involves the direction of a high-frequency energy beam through the object. If the beam detects an interruption, sound will reflect back and be collected by the pulse-echo equipment, which then amplifies it and displays it visually in video format. Ultrasonic testing is very sensitive and can determine the exact location of discontinuities, particularly gas pores, lamination, and other defects that are too small to be observed with other methods. While it requires interfacing with computers or equipment with built-in memory to produce a permanent record, it allows for a closer inspection of joints than radiographic testing can provide. Like radiographic testing, only highly trained professionals can perform ultrasonic weld testing.

While radiographic and ultrasonic testing each offer their own advantages and disadvantages, both forms of non-destructive examinations are indispensable to the welding industry. At Encorus Group, we offer these and other NDE options, all of which meet or exceed requirements and are performed by our experienced technicians using advanced equipment.
