Modern supply chains are complex, and there are immense costs of component failures, including recalls, downtime and safety incidents. Radiographic inspection offers a critical solution. This nondestructive testing (NDT) method can ensure product integrity and safety before they even enter the supply chain. It has numerous applications in manufacturing and is evolving to enhance quality assurance across various industries.
The Necessity of Quality Assurance
Quality assurance (QA) ensures that products, processes or services meet certain standards and expectations. A single defective component can delay an assembly line and erode trust with partners or customers. Component failure can also lead to legal liability or human endangerment. For instance, a microscopic flaw in an engine or a crack in a medical implant can lead to catastrophic failure.
Supply chain disruptions cost an organization approximately $184 million annually in lost productivity, expedited shipping costs and other factors. The frequency of them has increased in many industries due to the COVID-19 pandemic, geopolitical conflicts, increased cyber threats and more factors.
Brands must consistently meet expectations for high-quality products, and an objective QA plan is a key way to achieve this. While there are many ways to test an item’s quality across sectors, special attention is given to NDT methods that do not alter the component’s physical properties.
How Does Radiographic Inspection Work for Quality Assurance?
Radiographic inspection can be used for QA in various industries, including aerospace, construction, energy and manufacturing. Using X-rays or gamma rays to see inside objects, radiographic inspection can create a radiograph — a permanent visual record — of an item’s internal structure.
The tested material absorbs different amounts of radiation based on composition, density and thickness. A detector captures the radiation passing through to create the radiograph, which trained technicians then analyze. This NDT method can reveal flaws, material porosity and other characteristics without damaging the item.
Radiographic inspection enables predictive maintenance by detecting defects early on and preventing failure in high-risk appliances. Example uses include inspecting turbine blades for cracks and verifying the integrity of pipelines. It can also help manufacturers and engineers meet strict industry regulations and ensure the quality of their products.
The Evolution of Radiographic Methods
While radiography was film-based initially, there has been a shift to digital methods to serve modern supply chains better. Digital radiographic testing is now more efficient, offers easier data storage and sharing, and can lead to improved analysis. The images can also be stored without degradation for long-term trend analysis and documentable proof of QA.
The reliability of digital radiographic technologies is demonstrated across resources published by industry leaders, such as FUJIFILM Corporation. The two primary types are computed radiography (CR) and digital detector arrays (DDA), also known as direct radiography (DR).
CR imaging plates capture X-rays that are then scanned by lasers. The process takes only a few minutes and does not require chemicals. It can achieve high resolutions and serves as the bridge between analog and digital systems. Alternatively, DDA uses a solid-state panel detector to capture images by converting X-rays into digital signals. This nearly real-time imaging can lead to faster workflows and better signals. The technology’s initial investment is similar to that of CR.
The Impact of Radiographic Inspection on Supply Chain and Manufacturing
Radiograph inspection offers many benefits for critical sectors seeking to maintain QA.
Defect Prevention
Catching flaws early can significantly reduce scrap, rework and the risk of shipping faulty products. This technical imaging process can reveal hidden flaws within components and verify quality. The probability of detection (POD) for radiographic inspection testing is high in most applications, especially for catching larger flaws in an item.
Artificial intelligence (AI) can also enhance POD by identifying concerns humans may otherwise overlook. A study by the Oak Ridge National Laboratory revealed that an AI-powered X-ray framework can detect defects four times more effectively than traditional methods and can reliably identify flaws as small as 50 to 100 micrometers.
Regulatory Compliance
Radiographic inspection can help organizations meet stringent safety and quality standards set by the American Society for Testing and Materials and the International Organization for Standardization, among other regulatory bodies. The digital images from the advanced testing process serve as proof of inspection for documentation and audits.
Compliance is especially crucial for organizations handling sensitive data or potentially hazardous materials. For example, pharmaceutical corporations can use X-rays to detect contamination and ensure the correct weight to meet and maintain the high standards expected by their clients.
Brand Protection
Robust QA is crucial for fostering customer trust and protecting brand reputation, which can give a supplier a competitive edge. Radiographic inspection can help analysts identify problems before an item proceeds to the next stage in the supply chain. This can effectively safeguard users from potential hazards and prevent product recalls, which can lead to productivity drops and high mitigation costs. When a manufacturer can deliver reliable products with high QA, they can better protect their image and profitability.
Building More Resilient Supply Chains Through Better Insight
With radiographic inspection, supply chain professionals can receive essential insights into component integrity and assure the quality of their products. The methods — including CR and DDA — are becoming more accurate than ever before. Integrating advanced radiographic techniques into the workflow is an investment in creating safer products and more resilient supply chains.
