Fastener Testing – Eddy Current NDT Solutions
Inspection & Sorting Machines for Industrial Fasteners
Fasteners are essential components in a wide variety of industries. These small yet crucial elements play a vital role in ensuring the integrity and stability of structures, equipment, and assemblies. Reliable NDT methods are indispensable for ensuring the quality and performance of industrial fasteners.
At ibg, we offer advanced testing solutions designed to meet the stringent quality requirements of fasteners. In this landing page, we will explore the importance of fastener testing, the quality standards they must adhere to, and the role of heat treatment evaluation in guaranteeing their reliability. Discover how our innovative Eddy Current Testing technology simplifies the evaluation process, enabling you to ensure the quality and performance of your fasteners.
Fastener Heat Treatment Evaluation
Eddy Current Testing is a non-destructive testing method used to evaluate the heat treatment quality of fasteners. This technique involves inducing electrical currents in the fasteners and analyzing the resulting electromagnetic fields. By assessing the electrical conductivity and other properties, Eddy Current Testing provides valuable insights into the heat treatment process, ensuring fasteners meet the desired standards. Our cutting-edge fastener testing solutions incorporate Eddy Current Testing, enabling you to efficiently evaluate the heat treatment quality and guarantee the reliability of your industrial fasteners.
Inadequate or improper heat treatment of fasteners can result in a range of problems including but not limited to:
- Reduced strength
- Premature wear
- Susceptibility to corrosion
- Brittleness
- Breakage
- Failure under stress
Heat Treatment of Fasteners
Specially heat-treated screws and bolts are a requirement in the automotive sector and other industries. Stricter requirements are being placed on fasteners such as: bolts for seat rails, seat belt buckles, battery modules, self-piercing, and flow drill screws for body-in-white applications of electric vehicles. All parts are safety-relevant and must be appropriately safeguarded during production and heat treatment.
If you have your own inspection systems with rotary table and cameras, we can integrate an Eddy Current Test System to evaluate heat treatment deviations. You may not need a new inspection system. Cost-effective upgrades of your existing machines may be feasible, depending on the type and age of your equipment.
ibg NDT technology has been the first choice of leading inspection machine manufacturers worldwide for equipping new systems for years. We would be happy to advise you on how to integrate our non-destructive test solutions into your equipment. For over 40 years, thousands of customers worldwide have trusted our ibgNDT expertise.
Your machine operators who manage your camera-based inspection machines can learn how to operate ibgNDT eddy current instruments with a brief training. Our easy-to-use and easy-to-understand operating concept and proven Good Part Only Training ensures that.
Fastener Testing for the Automotive Industry
Emerging trends in the electric vehicles (EV) industry have led to an increased demand for and testing of those fasteners. The transition towards electric vehicles demands lightweight materials, enhanced performance, and increased safety measures. This shift has introduced new fastener designs, materials, and manufacturing techniques. As a result, demand for fastener testing solutions has grown exponentially to ensure the quality and durability of fasteners used in EV applications.
Fasteners are subject to stringent quality requirements to guarantee their reliability and durability. These quality standards aim to ensure that fasteners meet specific criteria, such as strength, resistance to corrosion, dimensional accuracy, and more. Meeting these demanding quality standards is crucial to avoid failures, ensure safety, and maintain the overall performance of the products and systems they are used in.
Part of the constructive concept for safety of EVs is specialty fasteners, which partly replace spot welding. Sophisticated heat treatment procedures are an important part in the manufacturing of these fasteners. This is followed by NDT (non-destructive testing) of the microstructure of these fasteners. Fastener production, manufacturing and quality teams are concerned with some conflicting objectives:
- 100% quality of fasteners according to the specifications
- On-going demands for cost reduction and productivity gains
- Shortages of qualified staff
