The AWS Certified Welder (CW) credential is earned through a hands-on performance test at an AWS Accredited Test Facility (ATF): you weld to a specified Welding Procedure Specification, an AWS Certified Welding Inspector inspects the result, and the ATF forwards your paperwork to AWS. There is no written exam and no prerequisite course. Prepare by choosing the test configuration that matches your target industry, practicing that exact configuration, and rehearsing self-inspection so your coupon passes on the first look.
What the CW Credential Actually Is — and What It Is Not
The CW is a performance-based welder qualification with no prerequisite courses or certifications. It documents that you passed a welding test at an Accredited Test Facility under a specific process, material, position, and code.
AWS describes the program as open to anyone with the welding skills to pass the required performance qualification test. There are no educational prerequisites, certification requirements, or minimum experience thresholds — welders come to it from vocational schools, apprenticeships, military training, technical colleges, or on-the-job learning. If you can produce the weld the test requires, you are eligible.
The program tests procedures used across several industries: structural steel, petroleum pipelines, sheet metal, and chemical refinery work, with facility-dependent options for pressure vessels and employer-specific or non-code procedures. Your resulting credential covers the process, material, and position you qualified in — which is why two CW holders can carry very different authorizations. Before booking anything, write down the exact work you intend to perform and match your test to it.
The governing document for the program is the QC47 Specification. Read it and its supplements before your test appointment; the ATF administering your test works under AWS Standard Welding Procedures or, in some cases, company-provided or non-code procedures. Your chosen facility can tell you which procedure your test follows. Note that AWS does not publish the detailed QC47 content or the acceptance criteria for each test in its program pages — those come from the governing documents and your ATF. Certification is also separate from licensing: some states and localities license welders with requirements that vary by jurisdiction, so check with your state or local licensing agency if your work may require a license.
- Performance-based format, no prerequisites, QC47 as the governing specification, and tests run at ATFs worldwide by appointment are confirmed on AWS's own program page.

How the Test Day Actually Runs: A Worked Walkthrough
You schedule with an ATF, weld to the governing WPS during a supervised appointment, and an AWS CWI inspects the weld. If you pass, the ATF sends your application, qualifications test record, and payment to AWS; if you fail, you can retest at any time with no limit on attempts.
Worked example — trace one hypothetical appointment end to end. A welder targeting structural shop work books a test at a domestic ATF. At the appointment, the welder deposits a sound weld following the facility's WPS; the evaluated work includes fit-up, assembly, and positioning, not just the arc time. An AWS Certified Welding Inspector inspects the completed weld. AWS states it receives the application, test results, and registration fee up to two weeks after the skill demonstration — this varies by facility, so confirm with your ATF — and the candidate should receive digital credential access by email roughly two to three weeks from the date AWS receives the application.
Two practical points follow from that sequence. First, your evaluation is not only about the weld bead: adherence to the WPS during fit-up, assembly, and positioning is part of the test, so practice the whole procedure, not just the arc. Second, failure is a scheduling problem, not a disqualification. If a welder fails any test, they can retest at any time — discuss a new date with the ATF representative, who handles scheduling.
Application logistics have moved online: beginning January 15, 2026, AWS no longer accepts paper applications for certifications or endorsements, and submissions go through the My AWS Portal. Fees for the weld test itself are set by individual ATFs and vary with the process and qualification involved, so contact your preferred facility for current pricing. AWS also notes that entry-level certifications like the CW often range from a few hundred to around a thousand dollars including testing fees and materials — treat that as a planning estimate, not a quote.
- Timeline checkpoints to confirm with your ATF: appointment booking, document submission after the weld, AWS processing window, and digital credential delivery by email.

Choosing Your Test Path: Structural, Pipeline, and Sheet Metal
Match the code and product form to your target sector. Structural steel welders commonly test under AWS D1.1, pipeline welders under API 1104, and sheet metal or refinery work follows its own paths — pick the one your employers actually specify.
AWS's own guidance maps sectors to tests: structural welders typically test under AWS D1.1, while pipeline welders may go for API 1104. The CW program covers plate welding in flat, horizontal, vertical, and overhead positions as well as pipe certifications on small- and large-diameter pipe. AWS's certification FAQ adds that a 6G pipe test is often described as among the most respected because it covers all positions on a fixed pipe — treat that as industry commentary on difficulty, not a program requirement for any particular job.
Know what your credential documents: the welding process, material, and position you qualified in. How far the qualified range extends beyond the exact coupon you tested — other thicknesses, diameters, or positions — depends on the governing code and your qualification test record, so check those documents rather than assuming either a narrow or a broad range. Credentials are also process-specific: if the shops near you run a different process than the one you trained on, add practice time in the market-relevant process before testing.
Practice exercise
Three welders are choosing their first CW test. (1) Ana works in a fabrication shop welding A36 plate in flat and horizontal positions on building structures. (2) Dev wants to join a cross-country pipeline crew. (3) Marco is aiming at small-diameter process piping in a chemical refinery. Using the sector-to-test mapping above, state which test path each welder should pursue and why.
Show answer
Ana: an AWS D1.1 structural steel plate test in the positions her shop's drawings require (flat and horizontal, per her description). Dev: an API 1104 pipeline test, which is the code AWS maps to pipeline work. Marco: he should not assume a code or pipe position from the refinery sector alone — he should ask his employer and the ATF which code and test configuration apply to his process-piping work, then book that test. Each welder's credential will document the process, material, and position tested; how far the qualified range extends is defined by the governing code and the qualification test record.
The reasoning follows AWS's published mapping between sectors and codes: D1.1 for structural steel, API 1104 for pipelines, with refinery and sheet metal paths in the CW program's industry list. The tempting shortcut is booking whichever test a nearby facility runs most often, or inferring a pipe position from the employer's industry alone — neither produces a credential that documents the actual job. Decide the target work first, confirm the code and configuration with the employer and ATF, then book that test.
| Decision point | Structural plate path | Pipe path |
|---|---|---|
| Common governing code | AWS D1.1 structural welding code | API 1104 or the pipe code the employer specifies |
| Product form tested | Plate coupons in flat, horizontal, vertical, or overhead positions | Pipe coupons, including fixed-position tests such as 6G |
| Typical fit | Construction, fabrication shops, structural steel erection | Pipeline, power piping, process piping employers |

Preparing for a Performance Test: Supervised Practice and the WPS
Formal training is not required, but AWS recommends practice and instruction. Get the ATF's WPS before you practice, arrange supervised booth time in your exact test configuration, and rehearse the procedure on paper with the exercise below.
The program imposes no training requirement: welders arrive from vocational programs, apprenticeships, military training, technical colleges, and on-the-job experience. AWS notes, however, that developing the skills to pass a performance test often requires practice and instruction, and many candidates attend welding schools or training programs. AWS publishes a welding school locator, and many schools coordinate with Accredited Test Facilities so students can test as part of their curriculum.
Before you practice, get two documents from your ATF: the Welding Procedure Specification your test will follow, and the code or standard that supplies the acceptance criteria. Your evaluation covers adherence to the WPS — fit-up, assembly, and positioning — not just the final bead. Ask your instructor to supervise practice in that exact configuration, and get the acceptance criteria from your governing code and ATF; this guide does not reproduce them.
Safety sits inside the professional scope AWS describes for Certified Welders: follow workplace requirements for personal protective equipment, ventilation, fire prevention, and safe equipment operation, and expect employers to set site-specific procedures. Common hazards include arc radiation, fumes and gases, electrical shock, burns, and fire. Separately, the Bureau of Labor Statistics notes that OSHA requires welders to complete training on electrical safety.
Be clear about what paper preparation can and cannot do. Walking through a WPS builds familiarity with the sequence of a test appointment; it cannot establish welding skill. Supervised booth time builds the hands-on ability, and only the CWI's inspection at the ATF decides the result.
Practice exercise
The card below is an explicitly hypothetical WPS summary created for practice — it is not a real procedure and carries no weldable values. Fields: process SMAW (stick); base metal carbon steel plate; joint single-V groove with backing; position 3G (vertical); backing: yes. Using only these fields, write the pre-weld checklist you would follow at an ATF appointment, and mark which steps the inspecting CWI evaluates as part of WPS adherence.
Show answer
A workable checklist: confirm the electrode and material requirements against the WPS; verify the base metal and joint preparation; check fit-up — root opening and alignment — against the joint design; assemble the joint and secure the backing; position the coupon in the 3G vertical orientation before striking an arc; then deposit the weld following the procedure. The CWI's evaluation covers the whole demonstration: AWS states that a welder's adherence to the WPS includes fit-up, assembly, and positioning, and the completed weld is inspected against the acceptance criteria of the applicable code.
Every checklist item traces either to a field on the card or to the three adherence steps AWS names — fit-up, assembly, and positioning. Notice what the card cannot tell you: amperage, travel speed, pass sequence, and acceptance limits. Those values come from the real WPS your ATF supplies and the governing code, so a hypothetical card must leave them blank; inventing them would teach you numbers that do not govern your test. Run this walkthrough before your first supervised session so booth time goes into welding rather than re-reading the procedure.
- Locate a welding school or training program through AWS's school locator, or ask your employer about instruction.
- Ask whether the program coordinates with an ATF and can test the configuration on your WPS.
- Practice the full procedure — fit-up, assembly, positioning, and the weld — under an instructor, in the exact process, material, and position you will test.
- Confirm your OSHA-required electrical-safety training is current before working on live equipment.

Keeping the Credential: Maintenance, Continuity, and Verification
Your CW stays valid as long as you maintain continuity: submit maintenance documentation every six months confirming you still perform the certified welding process, and keep your annual WeldCert Pro subscription active.
AWS states that Certified Welder certification remains valid as long as continuity is maintained. The mechanics, per the program requirements: complete the welder performance qualification test at an ATF, have the ATF submit your Certified Welder Application to AWS, purchase an annual WeldCert Pro subscription, and submit Maintenance (Continuity) of Welder Certification before it expires through WeldCert Pro, which checks that the certified welding process has been used. If continuity lapses, the certification can become inactive and requalification through testing is required.
Employers verify CW credentials through AWS's online tools: QuikCheck and the National Registry of Certified Welders (NRCW), where an AWS CW certification number can be checked for current status. Keep your maintenance filings current so the registry reflects an active credential — a lapsed card undermines the portability that makes the credential valuable.
Documentation discipline has a safety counterpart on the job. Certified welders are expected to follow workplace safety requirements, including proper PPE, ventilation, fire prevention, and safe equipment operation, while employers establish site-specific procedures. Arc radiation, fumes and gases, electrical shock, burns, and fire are the common hazards to manage in any welding environment.
- Time-sensitive items to calendar: annual WeldCert Pro subscription and six-month continuity submissions before expiration.
- Administrative specifics such as fees and portal procedures change — reconfirm with AWS and your ATF before filing.

Career Routes and What Comes After the CW
The CW is the common entry point for hands-on welding work in manufacturing, construction, and shipbuilding. From there, welders move toward inspection, supervision, or education credentials — most prominently the Certified Welding Inspector (CWI) — each with its own education and experience requirements.
Entry-level Certified Welders commonly work in manufacturing, construction, or shipbuilding across different processes and positions. With experience or advanced credentials such as the CWI or Certified Welding Supervisor (CWS), welders can move into inspection, quality control, supervision, project management, or specialties such as pipeline or aerospace work. AWS positions certification as helping demonstrate qualifications and improve advancement opportunities, not as a guarantee of any particular job or income.
If inspection interests you, the CWI path has a tiered qualification structure based on combinations of education and welding-based work experience, from one year of experience with a welding engineering bachelor's degree up to twelve years with less than an 8th-grade education. The CAWI credential exists for early-career professionals who have not yet met CWI experience minimums. Compare your own education and experience against that table to see which AWS credential fits next — the CW requires no prerequisites, but the professional-level credentials do.
- Preparation priorities from the official program: read QC47 and its supplements, confirm your ATF's WPS and code before booking, and rehearse the full test-day sequence including inspection.
| CWI entry tier (editorial summary) | Minimum welding-based work experience |
|---|---|
| Bachelor or higher in welding engineering/technology | 1 year |
| Associate or higher in related engineering technology, engineering, or physical science | 2 years |
| Engineering/technical courses toward a welding-related bachelor's | 3 years |
| Trade/vocational courses | 4 years |
| High school diploma or equivalent | 5 years |
| 8th-grade schooling | 9 years |
| Less than 8th grade | 12 years |
