Radiographic Testing (Rt) – Ndt Level I & Ii Training

Master radiographic testing techniques, X-ray/Gamma principles, film interpretation, and ASME code as per Level I & II.

What you'll learn

Understand the basic principles of Radiographic Testing and how radiation is used for internal defect detection.

Learn how to handle X-ray and gamma ray equipment safely and effectively during RT inspections.

Interpret radiographic film/images and identify common types of defects in welds and materials.

Understand key RT terms, exposure techniques, film processing, and applicable codes and standards.

Requirements

No previous experience in Radiographic Testing is required — the course is beginner-friendly.

Basic understanding of NDT or industrial safety is helpful, but not mandatory.

Access to RT equipment (for practical exposure) is useful but not necessary for theory-based learning.

Willingness to learn about radiation safety, inspection techniques, and quality control practices.

Description

This course provides in-depth training in Radiographic Testing (RT), a crucial method in Non-Destructive Testing (NDT) used to detect internal defects in welds, castings, and components using X-rays or Gamma rays.You’ll begin by understanding the basic physics of radiation, types of radiation sources (X-ray and Iridium-192/CO-60), and safety procedures. The course covers exposure techniques, film selection, sensitivity, IQI placement, and darkroom processing. Real-world images, radiographs, and interpretation examples help you understand defect types like porosity, slag, cracks, lack of fusion, and other volumetric discontinuities.A major focus is placed on film interpretation, code requirements (ASME Section V & VIII), and report preparation. You'll also learn how to evaluate image quality, detect unacceptable discontinuities, and follow proper documentation protocols and standards.Whether you’re preparing for Level I or II RT certification or want to expand your industrial inspection skills, this course equips you with the theoretical and practical knowledge needed. The content aligns with ASNT, ISO, and other international standards.The course includes downloadable charts, radiographic image samples, safety guidelines, and inspection checklists to reinforce learning. It is designed to support students, freshers, and working professionals aiming to succeed confidently in real-world RT inspection roles across industries and technical sectors worldwide.
