Comprehensive Guide to Infrared Thermography and Non-Destructive Testing (NDT)

Introduction

Infrared thermography is a cutting-edge technology used for non-destructive testing (NDT) in various industries, including electrical inspections, mechanical testing, material testing, and building inspections. By utilizing infrared thermal imaging cameras, professionals can conduct infrared thermography inspections to detect hidden issues such as insulation failures, leaks, and mechanical faults. This article provides a comprehensive overview of thermography testing, infrared inspection, and its applications across various sectors.

What is Infrared Thermography?

Infrared thermography, also known as IR inspection, is a non-destructive testing (NDT) technique that captures temperature variations across surfaces using an infrared thermal imaging camera. It is widely used for visual inspection, leak detection, and electrical thermographic surveys.

Thermography testing involves infrared thermal imaging to identify anomalies in structures, electrical systems, and mechanical components. Infrared inspection services provide a safer and more efficient way to inspect and maintain critical assets without physical disassembly.
