ISO 17639 Metallographic Examination of AM Welds
The ISO 17639 standard provides a systematic approach to inspecting and evaluating the microstructure, elemental distribution, and other properties of welds produced using additive manufacturing (AM) techniques. This service is particularly valuable for quality assurance in industries where precision and reliability are paramount, such as aerospace, automotive, and medical device manufacturing.
The process involves several key steps: specimen preparation, metallographic examination, and analysis. Specimen preparation is critical to ensure that the microstructure of the weld can be accurately observed and analyzed. This typically includes cutting the sample into a suitable size and shape, followed by mechanical polishing and etching to enhance contrast for better observation.
Once prepared, the specimen undergoes metallographic examination using optical or scanning electron microscopy (SEM). The aim is to identify any defects such as porosity, inclusions, and cracks. SEM offers greater resolution but can be more expensive than optical microscopy. This service ensures that all critical areas of the weld are examined thoroughly.
The analysis phase involves assessing the microstructure and elemental composition using techniques like energy-dispersive X-ray spectroscopy (EDX). These analyses provide detailed insights into the grain structure, distribution of elements, and any anomalies present in the weld. The results help determine whether the weld meets the specified quality criteria outlined in ISO 17639.
This service is crucial for ensuring that additive manufacturing processes produce high-quality products. By adhering to international standards such as ISO 17639, manufacturers can demonstrate compliance with regulatory requirements and enhance their reputation for reliability and precision.
