SCWI, the Senior Certified Welding Inspector: eligibility, the four exams, and the cost
Quick answer
What is the SCWI (Senior Certified Welding Inspector) and how do you qualify for it?
The Senior Certified Welding Inspector sits above the CWI. You must already hold the CWI for six of the past eight years and document fifteen years of experience, then pass four qualifier and coordination endorsement exams at $540 each. It is an advancement credential, never a starting point.
The Senior Certified Welding Inspector (SCWI) is the top rung of the American Welding Society inspector ladder. Nobody registers for it as a first credential: it is an advancement you pursue years into an inspection career, once your CWI tenure and your documented experience justify the step. This guide covers who actually qualifies, what the credential is made of, and roughly what it costs, from a site that sells no prep.
Who qualifies for SCWI?
SCWI is an advanced credential built on the CWI, so the gate is experience, not a lower entry bar. As AWS publishes the requirements, you must:
- Already be a CWI in good standing, certified as a CWI for six years within the past eight years. This is the hard prerequisite: no CWI, no SCWI.
- Document at least fifteen years of work experience in at least three of AWS’s qualifying functional areas, which include procedure development, base-metal control and application, welder and welding-operator experience, weld-discontinuity detection, repair-weld planning, written-procedure preparation, welder and procedure qualification, application of welding codes and standards, quality-control operational techniques, and welding education or instruction.
- There is no separate education requirement, because the education thresholds are already implied by the CWI you must hold to apply.
A vision test (the Visual Acuity Exam Form) is part of the application, as with the rest of the inspector ladder. Confirm your exact tenure and experience against the official SCWI application before you commit, because the counting rules are set by AWS.
What does the SCWI exam consist of?
SCWI is not a single new exam. You earn it by passing four computer-based endorsement exams that map to the qualifier and coordination endorsements:
- Welder Performance Qualifier (WPQ).
- Welding Procedure Qualifier (WPQ2).
- Welding Coordination and Quality Assurance.
- Nondestructive Examination (NDE) Coordination.
These are the same four endorsements a CWI can pursue individually. Passing all four is what elevates the credential to Senior. The detail pages for each, with format and pass marks, are WPQ, WPQ2, Welding Coordination and QA, and NDE Coordination.
What does SCWI cost?
Because SCWI is built from those four endorsement exams, its exam cost is four times the qualifier and coordination endorsement fee: 540 US dollars per exam for members, 630 for non-members (the non-member price includes a one-year AWS membership), verified against the AWS 2026 price list on 2026-07-24. Four exams therefore run on the order of 2,160 dollars for a member, before any AWS application or processing fee, which you should confirm on the current price list. The full dated line items are on the cost table.
That is a real investment, and it is why SCWI is worth treating as a long-horizon goal rather than an impulse: you pay four endorsement fees, and you must first have spent six-plus years as a CWI to be eligible at all.
What does an SCWI do that a CWI does not?
The scope reflects the seniority. A CWI performs hands-on inspection of welds. An SCWI operates a level up: managing inspection programs, interpreting complex codes, overseeing qualification practices, devising inspection procedures, and supervising Certified Welding Inspectors. In practice SCWI is the credential for inspectors moving into quality-management and program-oversight roles rather than staying purely field-based.
Should you be pursuing SCWI now?
If you are reading this to decide what to register for today and you are not yet a CWI, the answer is almost certainly no: SCWI is not a starting point and cannot be. Get the CWI first, build the years, and revisit SCWI once you hold the CWI, have the tenure, and have a role reason (a quality-management or program-oversight track) to advance. If that is not your path, SCWI is simply the reason the CWI is worth treating as the foundation of a long inspection career.
The credential ladder guide maps CAWI, CWI, SCWI, and the CWE and CRI cousins side by side, and the CWI exam guide covers the foundation credential you need before any of this.
