, Exam Overview & Content Outline
EXAM PURPOSE
Indiana Certified Welder certification covers welding processes, safety, metallurgy, blueprint reading,
and code compliance. Based on AWS D1.1 Structural Welding Code, ASME Section IX, API 1104,
and Indiana occupational standards for structural and pipe welding.
CONTENT DISTRIBUTION
• Welding Safety & PPE (20%) — OSHA, ANSI Z49.1, electrical safety, fumes, fire prevention, PPE,
confined spaces
• Welding Processes (30%) — SMAW, GMAW, FCAW, GTAW, equipment, parameters, techniques,
positions
• Metallurgy & Materials (20%) — Steel grades, heat treatment, HAZ, distortion, preheat, post-weld
heat treat
• Blueprint Reading & Symbols (15%) — AWS A2.4 welding symbols, joint design, measurements,
specifications
• Inspection & Codes (15%) — AWS D1.1, visual inspection, defects, NDT basics, welder
qualification
QUESTION FORMAT & SCORING
Each item presents four options. Correct answers are highlighted in green with checkmark (✓).
Every question includes detailed rationale with welding standards. Written exam requires 70%;
performance test requires passing bend tests per AWS D1.1.
STUDY STRATEGY
Master AWS D1.1 and welding symbols. Know SMAW/GMAW/GTAW parameters and techniques.
Understand metallurgy, preheat, and HAZ. Review OSHA safety and PPE. Study weld defects and
inspection criteria. Practice joint preparation and positions 1G-4G, 1F-4F.
CURRICULUM ALIGNMENT
Questions reflect 2026-2027 standards: AWS D1.1 Structural Welding Code, ASME Section IX, API
1104, AWS A2.4/A3.0, OSHA 29 CFR 1910.252, ANSI Z49.1, and Indiana welding standards.

, SECTION I: Welding Safety & PPE
1. ANSI Z49.1 requires welding helmet shade for SMAW 200 amps:
A. Shade 5
✓ B. Shade 10-12
C. Shade 2
D. No shade
Rationale: ANSI Z49.1: SMAW 60-160A = shade 10, 160-250A = shade 12, 250-550A = shade 14.
GMAW/FCAW similar. GTAW 50-150A = shade 11. Oxy-fuel = shade 4-6. Too light = arc eye; too dark =
poor visibility. Auto-darkening 9-13 adjustable. Protects from UV/IR radiation.
2. Electrical shock hazard in SMAW is reduced by:
A. Wet gloves
✓ B. Dry gloves, insulated boots, dry work area, proper grounding
C. Bare hands
D. Standing in water
Rationale: SMAW electrical safety: Dry leather gloves, rubber-soled boots, dry conditions. OCV 50-100V can
shock. Don't touch electrode and work simultaneously. Insulate yourself from work and ground. Ground
clamp close to work. GFCI recommended. Never weld in wet conditions.
3. Hexavalent chromium exposure occurs when welding:
A. Aluminum
✓ B. Stainless steel
C. Wood
D. Plastic
Rationale: Hexavalent chromium Cr(VI): Carcinogen. Produced welding stainless steel, chrome alloys.
OSHA PEL 5 µg/m³. Requires local exhaust, respirators if exceeded. Symptoms: respiratory, dermatitis,
cancer. Stainless SMAW/GMAW highest risk. Monitor exposure, medical surveillance.
4. Confined space welding requires:
A. No special requirements
✓ B. Permit, ventilation, attendant, rescue plan, air monitoring
C. One person only
D. No ventilation
Rationale: OSHA 1910.146: Confined space permit required. Hazards: toxic fumes, oxygen
deficiency/enrichment, fire. Ventilation, continuous air monitoring (O2, LEL, CO), attendant outside, rescue
plan, harness/lifeline. Training required. Hot work permit. Many fatalities from asphyxiation.
5. Fire watch after welding required for:
A. 5 minutes
✓ B. 30 minutes minimum
C. No watch needed
