How to become a CWI: eligibility, timeline and total cost

Becoming a Certified Welding Inspector takes qualifying work experience, an accepted application and passing results across three exam parts. A preparation course alone does not earn the credential. Start by checking your education and experience against AWS's requirements, then plan the application, appointments and costs together.

Who is eligible?

✓ The AWS CWI program page lists these minimum combinations of education and welding-based work experience:

  • Bachelor's degree or higher in welding engineering or welding technology: one year of experience.
  • Associate degree or higher in welding, engineering technology, engineering or a physical science, within AWS's listed categories: two years.
  • Applicable engineering or technical coursework toward a bachelor's degree or higher in welding: three years.
  • Successfully completed trade or vocational coursework qualifying for the education substitution: four years.
  • High school diploma or approved equivalency: five years.
  • Eighth-grade schooling: nine years.
  • Less than eighth-grade schooling: 12 years.

The education substitutions have limits; an unfinished course or an unrelated qualification does not automatically receive the maximum credit. AWS also requires a vision test and supporting records. Use its employment verification and visual acuity forms, and check how your actual duties fit the qualification requirements before paying. AWS decides whether your evidence qualifies.

What are the three parts?

The route includes Part A Fundamentals, Part B Practical and Part C Code Application. Part A addresses welding inspection knowledge; Part B assesses practical inspection applications; Part C tests using the selected code. Read the Part A guide and Part C D1.1 guide to plan separate study blocks.

✓ The CWI Examination User Guide requires 72% on each part and a 72% composite average. Initial exam training is optional. Choose preparation around your gaps rather than treating a seminar as an eligibility requirement.

How long does it take to become a CWI?

There are two timelines: earning the required experience and completing certification after you qualify. A candidate with a high school diploma needs at least five years of qualifying experience; someone who already has that experience is planning applications and exams, rather than starting a new five-year wait.

Use this sequence to build your calendar:

  • Gather education, employment and vision records. Resolve missing signatures before selecting a deadline.
  • Choose a Part B event using AWS's live seminar and exam schedule. Check its site code, exam date and application deadline separately from any seminar dates.
  • Apply and await the Part B confirmation letter. The User Guide gives approximately four to six weeks after submission for the letter and advises waiting for it before arranging travel.
  • Use the letter's eligibility code to book Parts A and C at Prometric. AWS recommends booking those seats at least 30 days ahead. The Part B booking and Prometric appointments are separate arrangements.
  • Leave time after the last exam: AWS describes two to four weeks for the score letter and six to eight weeks after scores are confirmed for issuing the credential materials.

These are published planning intervals, not a guaranteed completion date. Some preparation and scheduling can overlap. Your chosen Part B event, available Prometric seats, application corrections and any retesting determine the actual finish. Confirm the required sitting order in your AWS instructions before booking.

How much does it cost to become a CWI?

✓ The AWS 2026 price list lists initial exams at $1,255 member / $1,520 non-member. Initial exams with Part B training are $2,000 / $2,265; the CWI seminar-and-exam package is $3,070 / $3,335. These are alternative starting purchases, not amounts to add together.

Build your total as chosen exam or package + vision exam + references and extra preparation + travel and accommodation + time away from work + retest reserve. Obtain current quotes for the variable costs. For example, an exam-only non-member budget starts at $1,520 before those personal expenses; it is not an all-inclusive $1,520 route.

Listed initial exam prices include the applicable Prometric seat fees. The non-member initial price includes three-year Individual Membership; Student and Early-Career memberships do not qualify for member pricing. The User Guide adds a $125 processing charge for domestic applications sent by email or paper mail. Calculated from those published charges, a non-member exam-only application sent that way totals $1,645 before personal expenses.

Use the CWI cost guide for the full package comparison and retest charges. Read the retest rules before treating your reserve as sufficient for another attempt. International candidates should check pricing and deadlines with the AWS agent identified for their event.

What does a CWI do at work?

O*NET's inspection occupation profile describes reading drawings and specifications, measuring products, recording inspection findings, identifying nonconforming work and communicating needed corrective actions. These are useful duties to look for in a welding inspection job description. The profile covers a broader inspection occupation, not CWIs alone; each employer defines the actual assignment and required code experience.

Once your route is clear, try the Part A diagnostic or Part C check to organize study. Practice results help set priorities; AWS determines certification.
