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.

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.
