Non-Destructive Evaluation

Quality Assurance Through Non Destructive Evaluation

To continue manufacturing products of an unmatched quality, you have to have access to the science and data behind the products. We use a triangular approach to testing at Sivyer Steel Castings that blends ultrasonic, radiography, and physical testing in our lab.

The radiographic analysis looks for discontinuities like shrinkage, gas, porosity, and sand inclusions. All inspections are conducted by Level III SNT-TC-1A certified personnel. We use a 4MV Linear Accelerator that can x-ray through 13 inches of solid steel. Magnetic particle inspection using a state-of-the-art 20,000 amp wet particle machine, dye penetrant exams, or ultrasonic testing serve as the final step to ensure a quality casting.

Our laser scanning technology works in tandem with the state-of-the-art Romer Portable 3D Coordinate Measurement System. The six axis measuring arm provides accurate and specific dimensional analysis. We can scan both castings and patterns to compare against the initial 3D model, validating the planning process.

Metallurgical Lab Analysis and Tests

The physical testing in our metallurgical lab works in conjunction with highly evolved technological processes to help ensure that our products are meeting and exceeding industry performance standards. Examples of testing done in our lab include:

• A quantitative analysis of 22 elements including Nitrogen
• Tensile testing
• Hardenability
• Metallography
• Macroetching
• Electrical Discharge Machining (EDM)
