Study Plan: AWS Certified Welder
Week 1-2: Fundamentals Review
- Review welding process theory (SMAW, GMAW, GTAW)
- Study joint types and weld positions
- Practice reading welding symbols and blueprints
- Understand acceptance criteria (AWS D1.1)
Week 3-4: Position Practice
- Master flat (1G/1F) and horizontal (2G/2F) positions
- Progress to vertical (3G/3F) - practice both up and down
- Tackle overhead (4G/4F) - most challenging position
- Focus on consistent bead appearance and penetration
Week 5-6: Test Simulation
- Practice on test-spec materials (thickness, type)
- Time yourself - complete within test time limits
- Visual inspection - check for undercut, porosity, cracks
- Destructive testing practice (bend tests)
Week 7-8: Final Prep
- Take practice tests under exam conditions
- Review common failure points
- Equipment check - ensure all tools ready
- Mental preparation and test day logistics
Study Plan: AWS CWI Exam

Part C: Code Book
- AWS D1.1 Structural Welding Code
- Open book exam (bring your code book!)
- Tab and highlight your code book
- Know where to find information quickly
- Practice navigating the code
Code Prep:
• Create index tabs• Highlight key sections
• Practice timed lookups
Exam Day Strategy
