Welding Certification Guide: AWS Credentials and How to Get Certified
Welding certification is how a welder proves they can lay a sound weld to a specific standard. It is central to hiring and to code work. Here is how certification works and the main AWS credentials.
QUICK ANSWER
In the US, welding certification usually means qualifying to a welding procedure and standard, often those of the American Welding Society (AWS). A welder passes a hands-on performance test for a specific process, position, and material, verified by inspection. The AWS Certified Welder credential validates a welder skill, while the Certified Welding Inspector (CWI) credential qualifies professionals to inspect and judge welds.
What Certification Actually Tests
Welding certification is specific, not general. A welder qualifies for a defined combination of welding process, position, joint type, and base material, tested by producing a weld that passes inspection to a standard. A certification in one process and position does not automatically cover others.
The Main AWS Credentials
- Certified Welder (CW): a performance-based credential proving a welder can weld to a standard. Continuity must be maintained.
- Certified Welding Inspector (CWI): a widely respected credential for professionals who inspect welds, requiring an exam and experience.
- Employer or code qualification: many welders qualify to a specific code (such as structural or pipe) under an employer welding procedure.
Skill, proven
Welding is a physical skill certified by a physical test. No amount of classroom study substitutes for the hours of hand practice behind a passing weld.
Because it is a hands-on skill, welding training benefits from repetition. Learn the processes in types of welding processes, and see how simulation supports skill building in our welding simulation training and manufacturing programs.
WE BUILD THIS IN VR — THE PRIME VR
We build welding skill-building into VR and simulation, where trainees practice technique, angle, and travel speed with instant feedback, before consuming consumables or shop time. It multiplies the reps behind a passing certification test.

Ask employers what they use.
Test Positions and Materials
Certification applies to the position, process and material tested. Broader tests qualify for more work.
Plan tests strategically.
Preparing for a Test
Practice with the same coupon type and follow procedures. Consistent technique matters.
Have coupons inspected before testing.
Preparing for a Test
Practice the exact procedure and position beforehand. Prepare joint and equipment carefully.
Maintaining Credentials
Some certifications require continuity or retesting. Keep records.
Track expiration dates.
What Is Actually Certified
A welding certification qualifies a welder to produce a specific type of weld under a specific procedure, and it is narrower than most people assume.
The qualification is tied to variables including process, material, thickness range, joint configuration, position and the presence of backing.
A welder qualified in one configuration is not thereby qualified in another, and employers who assume otherwise discover it at inspection.
The Procedure Specification
The welding procedure specification defines how a weld is to be made, covering process, filler metal, electrical parameters, preheat, interpass temperature and technique.
It is supported by a procedure qualification record documenting that a test weld made under those parameters met the required properties.
Welder qualification demonstrates that a person can produce a sound weld following a qualified procedure, which is why the two documents work together.
Positions and Their Codes
Position designations describe the orientation of the weld, covering flat, horizontal, vertical and overhead, with separate designations for plate and for pipe.
Qualification in a more demanding position generally covers less demanding ones, and knowing which coverage a test provides determines whether a single test is sufficient.
Pipe positions, particularly fixed positions requiring the welder to work around the joint, are the most demanding and the most widely valued.
Testing
Tests are evaluated by visual inspection first, and welds that fail visual examination do not proceed to further testing.
Destructive testing, typically bend tests, assesses soundness through the cross section, while radiographic or ultrasonic examination is used where the governing code requires it.
The test is performed under the same conditions the qualification claims to cover, and any deviation from the essential variables invalidates it.
Maintaining Qualification
Qualification lapses if the welder does not use the process within a defined period, and continuity records are what demonstrate that it has been maintained.
Employers commonly maintain continuity logs, and a welder who changes employers may need to requalify depending on how the governing code and the new employer handle transfer.
Some certifications require periodic renewal independent of continuity, so the specific requirements of the governing code should be confirmed.
Preparing for a Test
Practicing the exact configuration and position with the same process and consumables is what produces a pass, and general skill does not substitute for that specificity.
Simulation and structured practice build technique and consistency efficiently before consuming test material and testing fees.
The applicable welding code, employer procedures, the governing procedure specification and any client requirements determine what is required, and those should be confirmed before testing.
Common Mistakes and How to Avoid Them
Common errors include assuming one qualification covers unrelated configurations, testing without practicing the exact position and thickness, letting continuity lapse unnoticed and working outside the essential variables of the qualified procedure.
Supervisors can help by making it acceptable to pause and ask. A culture where questions are treated as competence rather than weakness produces fewer errors in welding qualification.
How Employers Evaluate Readiness
Employers assess welders on test pass rates, weld rejection and repair rates during production, inspection findings, consistency across positions and whether continuity records are maintained without prompting.
Keeping Skills Current
Codes are revised and projects specify particular editions and client requirements. Confirming which code and edition governs the work prevents qualifying under a standard the project does not accept.
Planning and Preparation
Preparation includes confirming which code and configuration the test must cover, reviewing the governing procedure specification, practicing the exact position and thickness with the same consumables and confirming test facility and inspection arrangements.
Documentation That Holds Up
Welder performance qualification records, procedure specifications and qualification records, continuity logs and inspection reports are what establish that a weld was made by a qualified welder under a qualified procedure.
Frequently Asked Questions
What is an AWS welding certification? +
It is a credential from the American Welding Society that validates a welder ability to produce sound welds to a defined standard, or, in the case of the Certified Welding Inspector, to inspect and judge welds. Certifications are specific to processes, positions, and materials.
How long does it take to become a certified welder? +
It varies widely with the individual and the certification. A focused welding program can prepare a candidate in months, but building the hand skill to reliably pass tests across positions and processes takes sustained practice.
Does a welding certification expire? +
Performance certifications typically require maintained continuity, meaning the welder must keep welding with the process to stay qualified. Rules depend on the certifying body and code, so welders should confirm the maintenance requirement for their credential.
What does AWS certification prove? +
That a welder passed a test to a specific code and procedure.
Can one test qualify me for all positions? +
Not always, as qualification depends on the test position and limits in the code.
