Parallel surfaces of adjacent parts are joined at their common edge. Weld Typologies
Stay up-to-date with the latest advancements in welding inspection techniques and technologies. From visual inspection to NDT methods, this guide has got you covered.
The most severe type of discontinuity. They can be hot cracks (occurring during solidification) or cold cracks (occurring hours or days later due to hydrogen embrittlement and stress). 5. Nondestructive Testing (NDT) Methods
The area of base metal that did not melt but had its mechanical properties altered by heat. This area is highly susceptible to cracking.
Understanding AWS WIT-T:2020 Welding Inspection Technology Welding inspection ensures the structural integrity, safety, and compliance of fabricated components across industries like aerospace, infrastructure, and oil and gas. The American Welding Society (AWS) publishes standard reference materials to train and certify professionals. Among these, the manual is a foundational text for aspiring Certified Welding Inspectors (CWIs). 1. Overview of the AWS WIT-T:2020 Manual i--- Welding Inspection Technology 2020 Pdf
Checking joint geometry, root opening, bevel angles, and alignment to prevent built-in stresses or lack of fusion. In-Process Responsibilities
First published by the AWS, Welding Inspection Technology is the core reference for the AWS Certified Welding Inspector (CWI) program, the most recognized and respected certification in the industry. This is more than just a textbook; it is a comprehensive curriculum designed to equip both aspiring and seasoned professionals with the knowledge required for the demanding role. If you want to become a CWI, this book and its companion workbook are essential for your exam preparation. Many professionals who have used this material agree that it is an invaluable resource for learning and a powerful tool for career advancement in welding inspection.
Built on consensus, these offer guidelines or accepted rules for industry practices.

Yes – the AWS CWI exam typically follows a 5-year cycle. The 2020 edition is valid until the 2026 revision. However, always check the latest CWI Body of Knowledge on AWS’s website for code updates.
Utilizing Magnetic Particle Testing (MT) and Liquid Penetrant Testing (PT) for surface-breaking discontinuities. Key Updates in the 2020 Edition
Utilizes X-rays or gamma rays to produce a volumetric interior view of the weld.
Use the review questions at the end of each module to test retention without looking at the text. The most severe type of discontinuity
A quick Google search reveals dozens of sites claiming to offer the Welding Inspection Technology 2020 PDF for free. Here is the reality:
Before an arc is ever struck, the inspector must lay the groundwork for compliance:
: Guides the inspector through the governing documents, such as AWS D1.1:2020 , which provides critical inspection criteria for static and cyclic loads.
The weldability of steel is largely dictated by its chemical composition. The Carbon Equivalent formula calculates the combined effect of various alloying elements (like Manganese, Chromium, and Molybdenum) relative to Carbon. A higher CE indicates a greater risk of martensite formation—a hard, brittle microstructure highly susceptible to . To mitigate this, inspectors must enforce strict preheating and post-weld heat treatment (PWHT) regimes. 4. Understanding Weld Discontinuities vs. Defects
