I see you searching for "Welding Inspection Technology 2020 PDF free download." Be careful. The free scans floating around on forums are usually missing Chapters 8 and 9 (the math and NDT tables). Those chapters are 15% of the CWI exam.
The real fix? If your PDF is broken, buy the AWS WIT Workbook to go with it. The 2020 PDF alone won't make you a CWI. You need the Module Quizzes.
TL;DR: Use "Print to PDF" to fix rendering errors. Turn off forms in preferences. If the file is dead, call AWS. Don't trust free scans—they are missing the NDT tables.

The report below covers the AWS WIT-T:2020 Welding Inspection Technology manual, which is the 6th edition published by the American Welding Society.
Regarding the "fix" in your query, it likely refers to official errata sheets or correction procedures for inspection reports. AWS frequently issues errata to fix typographical errors or incorrect symbols found in their 2020 publications. 1. Manual Overview: AWS WIT-T:2020
The Welding Inspection Technology (6th Edition) is a core resource for anyone pursuing the Certified Welding Inspector (CWI) credential. It covers technical, ethical, and safety aspects of the profession.
Key Modules: The manual is divided into 10 chapters, including: Chapter 1: Welding Inspection and Certification. Chapter 2: Safe Practices for Welding Inspectors. Chapter 3: Metal Joining and Cutting Processes. Chapter 5: Documents Governing Welding Inspection. Chapter 10: Visual Inspection and Other NDE Methods. Identification: Print ISBN: 978-1-64322-095-6. PDF ISBN: 978-1-64322-096-3. 2. Official "Fixes" (Errata & Updates)
AWS identifies and fixes errors in their standards through Errata Sheets. If you are using the 2020 edition, ensure you check for these updates to avoid using outdated or incorrect technical data. WIT-T:2020 Welding Inspection Technology i welding inspection technology 2020 pdf fix
Purpose: To provide a comprehensive background for welding inspectors (experienced or novice) regarding the technical and ethical aspects of the job.
Key Identification: Print ISBN: 978-1-64322-095-6; PDF ISBN: 978-1-64322-096-3. 2. Core Curriculum Modules
The manual is divided into chapters (often referred to as Modules in the companion workbook) that cover the Body of Knowledge required for AWS certification: Key Focus Areas 1 Inspection & Certification Responsibilities, ethics, and CWI/CAWI/SCWI levels. 2 Safe Practices Protective equipment, fumes/gases, and fire prevention. 3 Metal Joining & Cutting Detailed processes like SMAW, GMAW, FCAW, and GTAW. 4 Weld Joint Geometry Joint types, terminology, and standard welding symbols. 5 Governing Documents Codes (e.g., AWS D1.1), standards, and specifications. 6 Metal Properties
Destructive testing methods and mechanical/chemical properties. 7 Metric Practice Metric system basics and conversion factors for inspectors. 8 Welding Metallurgy Structure of metals and effects of heat during welding. 9 Discontinuities
Identifying weld and base metal defects (cracks, porosity, etc.). 10 Visual Inspection (VT) NDE methods and interpreting inspection results. 3. Critical Responsibilities for Inspectors
The 2020 standards emphasize that the inspector's role occurs in three distinct phases:
Before Welding: Review drawings, check joint preparation (root opening, groove angle), and verify materials/consumables.
During Welding: Observe welder technique, verify WPS (Welding Procedure Specification) settings, and check interpass cleaning.
After Welding: Perform visual inspection for defects (undercut, cracks), check dimensions against drawings, and document results. 4. Related Certification Resources Welding Inspection Documentation Form | PDF - Scribd
Troubleshooting Your AWS Welding Inspection Technology (WIT-T:2020) PDF A: This is a font substitution error
If you are a Certified Welding Inspector (CWI) candidate or a seasoned pro using the AWS Welding Inspection Technology (WIT-T:2020)
manual, you might have run into issues with the digital version. Whether your PDF won't open, shows a "Please Wait" screen, or contains outdated information, this guide will help you fix common problems and ensure you’re studying with the most accurate data. 1. Fix the "Please Wait" Error Many AWS publications, including digital PDFs, use XFA (XML Forms Architecture)
, which often crashes standard web browsers or native viewers like macOS Preview. The Solution : Open the file using the latest version of Adobe Acrobat Reader Alternative
: Use a "flattening" tool to convert the XFA form into a standard, static PDF that works on any device. 2. Update Critical Data with Errata Sheets
AWS frequently identifies typographical errors or technical inaccuracies after a manual is printed. For the 2020 editions (like the WIT series and D1.1), these corrections are essential for passing your exams. Check the Official Errata : AWS posts all corrections on their Official Errata Page Key 2020 Corrections
: Common fixes in the 2020 cycle include corrected symbols (e.g., using instead of
for groove angles) and missing definitions for terms like "interpass temperature". 3. Verify You Have the Latest Printing
The WIT-T:2020 and its companion workbook (WIT-W:2020) have multiple printings to incorporate these fixes. Workbook (WIT-W:2020) : Ensure you are using the 3rd Printing
or later for the most up-to-date answer keys and module questions. Manual (WIT-T:2020)
: Verify your ISBN (Print: 978-1-64322-095-6 | PDF: 978-1-64322-096-3) against the AWS Bookstore to see if a newer version has replaced your current file. 4. Ensure PDF Accessibility Author Note: Always support the American Welding Society
If your PDF is readable but difficult to navigate on a tablet or mobile device: Enable Bookmarks : If bookmarks are missing, use Adobe Acrobat Pro
to run an accessibility check and automatically generate a table of contents for faster navigation between modules. Metadata Cleanup
: If downloading from a cloud service like Amazon S3 and the file forces a download instead of opening in your browser, check that the "Content-Type" is set correctly to application/pdf Essential Links for CWIs AWS Errata Sheet - D1.1/D1.1M:2020
Older PDF engines fail where browsers succeed.
Note: This method flattens any interactive fields or layers, but for a static welding inspection manual, it is perfect.
If you're looking for a specific PDF document titled or related to "i Welding Inspection Technology 2020" and are experiencing issues (implied by "pdf fix"), here are some suggestions:
When all else fails, use Ghostscript to reinterpret the raw data.
Open Command Prompt as Administrator and run:
gswin64c -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=fixed_output.pdf damaged_input.pdf
Ghostscript ignores many minor syntax errors that break standard readers. It is the most powerful free fix for structural corruption.
