I cannot develop a genuine review of a specific 2020 PDF titled "i--- Welding Inspection Technology" for a few important reasons:
If you compare the 2015 PDF (still widely circulated) to the official 2020 edition, the differences are substantial: i--- Welding Inspection Technology 2020 Pdf

A critical distinction taught in the AWS curriculum is the difference between a discontinuity and a defect: mechanical properties like tensile strength
The exam tests precise vocabulary definitions. Do not confuse "discontinuity" with "defect." Master the Math: Memorize the heat input equation (
Welding alters the molecular structure of metals. This area focuses on how heating and cooling cycles affect the Heat-Affected Zone (HAZ), mechanical properties like tensile strength, and the weldability of various carbon and alloy steels. 5. Destructive and Non-Destructive Testing (NDT) Evaluating a weld requires distinct testing methodologies:
