Electromagnetic NDT

What is Electromagnetic Testing and Why is it Important? 

Electromagnetic Testing (ET) is a widely used non-destructive testing (NDT) method that uses electromagnetic fields to detect surface and near-surface defects in conductive materials. This method is essential in industries requiring precise defect detection, such as aerospace, oil and gas, power generation, and manufacturing.  

By identifying flaws such as cracks, corrosion, and material loss early, Dexon Technology’s advanced electromagnetic testing solutions help operators prevent failures, ensure safety, and maintain regulatory compliance. 

Common Problems and How Electromagnetic Testing Provides Solutions 

Industries that rely on metal components frequently encounter problems such as stress fatigue, material degradation, and corrosion, which can compromise safety and performance. Electromagnetic testing plays a vital role in identifying these issues efficiently without requiring direct contact or surface preparation, making it ideal for rapid and accurate assessments. 

Electromagnetic testing helps detect and solve these issues by: 

• Surface and Near-Surface Crack Detection: Eddy Current Testing (ECT) generates electromagnetic fields that identify fatigue cracks, stress-induced defects, and discontinuities in conductive materials, even through coatings and non-ferrous surfaces. 

• Corrosion and Wall Thinning Assessment: Remote Field Testing (RFT) and Pulsed Eddy Current (PEC) techniques measure wall thickness and pinpoint corrosion under insulation or coatings without requiring material removal. 

• Coating and Insulation Integrity Checks: Electromagnetic testing can assess the condition of protective coatings and detect subsurface defects without disrupting operational assets. 

• Fast and Non-Contact Inspections: Unlike traditional methods, electromagnetic testing allows for rapid scanning of large surface areas without the need for couplants or surface cleaning, reducing downtime and inspection costs. 

By integrating electromagnetic testing into routine maintenance programs, Dexon Technology helps clients detect flaws early, prevent structural failures, and extend the operational lifespan of their assets. 

Inspection Modes 

• Online Inspection: Conducting assessments while equipment remains operational, minimizing service disruptions. 

• Offline Inspection: Performing detailed inspections during scheduled maintenance shutdowns for in-depth evaluations.
