AWS welding certification adds an average of $10,000–$15,000 to your annual income, and it is the only credential that follows you from employer to employer without retesting. If you are working in structural steel, pipeline, or fabrication without an AWS Certified Welder card, you are leaving money on the table and limiting which jobs you can legally bid for.
The AWS system is not a single certificate. It is a ladder of credentials that spans from entry-level performance testing through senior inspection qualifications, each built for a different career stage. This guide maps the full system, explains exactly how the CW exam works, and tells you when each credential is actually worth pursuing

Qualified vs. Certified: A Distinction That Matters
Before anything else, one terminology issue needs to be cleared up, because confusion here creates real problems in the workplace.
In welding, “qualified” and “certified” are not interchangeable. AWS draws a clear line between them:
A qualified welder has passed a performance test administered by or for a specific employer under a Welding Procedure Specification (WPS). That qualification is valid for that employer’s work. It does not transfer when you change jobs.
A certified welder has passed the same type of performance test at an AWS Accredited Test Facility (ATF) under the CW program. That certification is portable; it follows you from employer to employer, and you present the credential card rather than retesting each time you change jobs.
Most welders who have been working for years are qualified in their employer’s processes without being AWS certified. Both are legitimate. The difference matters when you switch employers, compete for federal contract work, or move into structural or pipeline welding, where AWS certification is explicitly required.
The AWS Certification Ladder
AWS credentials serve different career stages. Here is the full structure:
| AWS Credential | Abbreviation | Who It Is For | Career Stage |
| Certified Welder | CW | Working welders validating specific process/position skills | Entry to mid-career |
| Certified Associate Welding Inspector | CAWI | Welders aspiring to inspection roles without enough experience yet for CWI | Mid-career |
| Certified Welding Inspector | CWI | Experienced welders moving into quality assurance and inspection | 5+ years of experience |
| Senior Certified Welding Inspector | SCWI | CWIs seeking the highest inspection credential | 6+ years as CWI |
| Certified Welding Supervisor | CWS | Welders moving into crew and operations leadership | Mid to senior career |
| Certified Welding Educator | CWE | Professionals teaching welding in formal programs | Career changers to education |
| Certified Welding Engineer | CWEng | Engineers working in welding design and application | Engineering background required |
| Certified Robotic Arc Welding | CRAW | Technicians operating automated welding systems | Technology-focused specialization |
For most welders, the relevant path is CW → CWI → SCWI, depending on whether you want to stay in production welding or move into inspection and quality assurance. The other credentials serve specific career pivots rather than the core welding path.
The AWS Certified Welder (CW): Your First Credential
The CW is where every AWS certification journey starts. It is a performance-based credential; you demonstrate that you can produce welds meeting a specific standard, under specific conditions, using specific processes.
The CW program is open to anyone with a talent for welding; there are no prerequisite courses or prior certifications required. Every certification a welder earns through the CW program increases the range of welding jobs they are qualified to perform.
No prior experience is formally required to apply. What is implied is that you can actually pass the test, which demands real skill. Walking into an ATF having never welded professionally is technically allowed, and practically inadvisable; most successful first-time test takers have at minimum completed a trade school program or spent time in a production welding role.
What the CW tests: The CW exam covers processes and positions across four primary industry applications:
- Structural steel welding (AWS D1.1)
- Petroleum pipeline welding (API 1104)
- Sheet metal fabrication
- Chemical refinery welding
Each test is specific to a process (SMAW, GMAW, GTAW, FCAW), position (1G, 2G, 3G, 4G, 5G, 6G), base material, and thickness. Passing a test in one combination does not automatically qualify you for others. The more process/position combinations you test in, the broader your credential coverage becomes, and the more valuable you are to employers who need flexibility across job types.
How the CW Exam Actually Works
Step 1: Choose your process and position. Decide which process and position you want to test first based on your target industry. Pipeline work demands 5G or 6G pipe positions. Structural work typically requires a 3G vertical and a 4G overhead plate. Start where your career goal points, not wherever is easiest.
Step 2: Find an Accredited Test Facility. CW testing only happens at AWS Accredited Test Facilities. These facilities adhere to strict standards for welder testing and can test welders to AWS Standard Welding Procedures, industry standard specifications, and company-supplied specifications. Many trade schools are ATFs. If you graduated from an accredited program, your school may offer testing.
Step 3: Submit your application and pay the fee. The AWS application fee is $50 regardless of membership status. Contact the ATF directly for their exam pricing, which varies by facility and test type. Total costs, including both fees, typically run $200–$400 per test. For Texas ATF, you can visit our guide: Best Welding Schools in Texas: Programs, Costs, and Certification Paths.
Step 4: Take the practical exam. On test day, you perform a weld according to the Welding Procedure Specification. An AWS Certified Welding Inspector evaluates your weld, assessing your adherence to the WPS, including fit-up, assembly, and positioning. There is no written component for the CW. The evaluation is entirely hands-on. You either produce an acceptable weld or you do not.
If you fail, you can retest at any time; there is no mandatory waiting period. Discuss scheduling with the ATF representative.
Step 5: Receive your CW card. Passing results in an AWS Certified Welder card documenting your specific qualifications. This card travels with you from employer to employer. Present it instead of retesting when you change jobs.
How Much Does AWS Welding Certification Cost?
The total cost of AWS CW certification has two parts: the AWS application fee and the Accredited Test Facility (ATF) exam fee. You pay both separately.
| Cost Item | Amount | Notes |
| AWS CW application fee | $50 | Paid to AWS; same for members and non-members |
| ATF exam fee | $150–$350 | Varies by facility and process tested; contact ATF directly |
| Total per test | $200–$400 | Per process/position combination |
| Retest fee | Same as above | No additional penalty; retests at standard cost |
| CWI exam fee (members) | $895 | AWS member pricing as of 2024 |
| CWI exam fee (non-members) | $1,150 | Standard pricing as of 2024 |
| SCWI exam fee | Contact AWS | Pricing varies; see aws.org for current rates |
If you are testing multiple processes and positions, the cost multiplies per test. A welder targeting both a 3G plate and a 6G pipe qualification, for example, pays the application fee once but takes two separate performance tests at the ATF’s per-test rate. Budget $400–$800 for a two-process initial certification.
The 6-Month Renewal Requirement
According to the Code of Acceptance, CW certification remains valid only while welders keep submitting certification maintenance forms every six months to AWS. Most welding codes require this maintenance on a six-month cycle, and there is a 60-day administrative extension period after expiration, but no provision for full recertification without retesting.
What this means in practice: if you stop submitting the maintenance form, your certification lapses, and you must retest from scratch. The maintenance form confirms you have been actively welding using the qualified process during that period. If you change jobs and stop using a particular process, that certification can lapse even while others remain current.
Keep a calendar reminder. Submit the form on time. This is an administrative step that costs almost nothing but prevents losing credentials you worked to earn.
Advanced AWS Certifications and When to Pursue Them
Certified Associate Welding Inspector (CAWI) The CAWI is designed for welders who want to move into inspection but do not yet have the five-plus years of experience the CWI requires. AWS developed the CAWI credential specifically for young professionals who aspire to a career in welding inspection but need more time to meet the minimum experience requirement for CWI.
It uses the same three-part exam as the CWI. Pursue this if you are targeting an inspection career and are in your first few years of welding work.
Certified Welding Inspector (CWI) The CWI is the most recognized advanced credential in the welding field. The CWI exam consists of three parts:
Part A: 150 multiple-choice questions on welding fundamentals, processes, safety, and inspection;
Part B: a practical hands-on assessment using weld samples and inspection tools;
Part C: an open-book test applied to a selected welding code, such as AWS D1.1 or API 1104. A minimum score of 72% is required in each section to pass.
To qualify for CWI, candidates must pass a vision test and present a combination of qualifying education and welding-related work experience, with supporting documentation.
The experience requirement varies by education level; a high school diploma with no college requires approximately five years of welding-related work. An engineering degree reduces that requirement substantially.
Senior Certified Welding Inspector (SCWI) The SCWI is the ceiling credential for inspection professionals. Candidates must have held CWI certification for at least six of the past eight years, and must complete four specific CWI endorsements: Welder Performance Qualifier, Welding Procedures Qualifier, Welding Coordination and QA, and Nondestructive Examination Coordination. SCWIs typically earn $90,000–$120,000 annually according to AWS data, representing the top of the welding inspection pay scale.
How AWS Certification Affects Your Pay
The salary premium for AWS-certified welders is real and documented across industry sources. Using the BLS national median of $51,000 for all welders as the anchor:
| Certification / Career Stage | Typical Annual Salary | Source |
| Non-certified welder (national median) | $51,000 | BLS OEWS May 2024 |
| AWS CW certified (general welding) | $55,000 – $65,000 | BLS + industry benchmarks |
| AWS CW with 6G pipe qualification | $65,000 – $90,000 | Pipeline sector data |
| Certified Welding Inspector (CWI) | $80,000 – $105,000 | Industry salary surveys |
| Senior Certified Welding Inspector (SCWI) | $90,000 – $120,000 | AWS compensation data |
Certified welders average $24–$31 per hour, roughly 30% above non-certified peers. At 2,080 annual hours, that premium equals $10,000–$15,000 in additional annual income from the CW credential alone. The CWI step represents an even larger jump, moving from production welding to quality assurance, which typically adds $25,000–$50,000 annually, depending on industry and location.

Frequently Asked Questions
Is AWS certification required by law?
Not universally. AWS certification is not a legal requirement in most states, but many employers and federal contracts require AWS-certified welders, particularly for structural steel, bridges, and pipeline work.
Does AWS certification expire?
The CW credential does not have a fixed expiration date in the traditional sense, but it lapses if you do not submit a maintenance form every six months confirming active use of the qualified process. There is a 60-day administrative extension after the deadline, but no recertification provision; lapsed certification requires retesting from scratch.
Can I get AWS certified without going to trade school?
Yes. The AWS CW program is open to anyone and has no prerequisite courses or prior certifications required. However, “no requirement” does not mean no preparation is needed.
How many AWS certifications can I hold at once?
There is no limit. Each CW test you pass in a specific process and position adds a qualification to your record. A welder can hold CW qualifications in MIG, TIG, Stick, and flux-core across multiple positions simultaneously.
What is the hardest AWS welding test?
Many experienced welders consider the 6G pipe weld, a fixed pipe at 45 degrees requiring welding in all positions simultaneously, to be the most challenging test, particularly using SMAW or GTAW.
Conclusion
AWS certification is not a single milestone; it is an ongoing process of adding credentials that expand what you can do, who you can work for, and what you can earn. Start with the CW in the process and position most relevant to your target industry.
Maintain it diligently every six months. Add qualifications as your skills and career direction develop. Then, evaluate whether the CWI path makes sense based on where you want to take your career long-term.
