Active thermography (AT) is a nondestructive testing method that uses advanced infrared camera technology and software to inspect subsurface defects in materials like those used in aerospace and automotive industries.

Conformable/flexible digital detector array (DDA) panels are revolutionizing industrial radiography by enabling comprehensive imaging of complex shapes across sectors like aerospace, oil and gas, automotive, construction, and electronics. This technology improves nondestructive testing and image quality, supported by key ASTM standards.

Ethics in Nondestructive Testing (NDT) are vital, as inspectors' decisions directly impact safety. Unethical practices, such as skipping inspections, using forged documents, and misusing inspection stamps, can lead to serious consequences and compromise industry integrity.

Neutron imaging enhances aerospace valve inspection by detecting issues traditional methods like X-rays miss. It reveals contaminants and allows for detailed 3D models, improving the assessment of complex valve assemblies.

Additive manufacturing (AM) is revolutionizing industries by enabling the production of complex metallic components, but it also presents unique challenges in quality assurance. This article examines the vital role of nondestructive testing (NDT) in ensuring the integrity and reliability of AM products.

Paul Lang, chief global strategy officer for the American Society for Nondestructive Testing (ASNT) and executive director for ASNT Certification Services LLC (ASNT CS), shares his thoughts on trends and liquid penetrant testing.

Batteries are key to electrification, demanding high-quality control and efficient production. The use of Automated Defect Recognition (ADR) and other technologies is critical as the industry aims to scale up to meet the rising demand from electronics, electric vehicles, and energy storage sectors, while also minimizing environmental impacts.

Corrosion prevention is vital for quality assurance in metal goods manufacturing. It helps avoid production delays and customer complaints from rust. Key strategies include four types of corrosion testing: VIA, humidity and salt fog, and iron chip testing. These tests aid in selecting effective protection methods and the right rust preventative dosage.

Additive manufacturing (AM), or 3D printing, is crucial for producing complex, accurate parts with minimal waste. Ensuring the quality of raw materials and finished metal parts is essential for its success. This paper emphasizes the need for compositional analysis and strict quality control in AM.

Eddy current inspection is one of the five main non-destructive testing (NDT) methods in the industry, alongside liquid penetrant, magnetic particle, ultrasonic, and radiographic testing. Due to its complex theoretical basis, it is the least used and hardest to understand.
