Welder Certifications (Which Ones Are Worth It)
Last updated:
Welding is a trade where the credential is the proof: most welder certifications are performance qualifications, meaning you pass a hands-on test weld to a written procedure and a coupon gets inspected or radiographed. That makes a current, relevant qualification far more useful than a generic certificate, because it states the exact code, process (such as SMAW, GMAW, FCAW, or GTAW), position, and material you are cleared to weld.
Below are the welder certifications and qualifications worth considering, who each is for, and how to list them on your resume so they actually help. Note that requirements are driven by codes and by the employer or jurisdiction, and many qualifications must be kept current through continued work or periodic retesting.
Top certifications for a Welder
Welder Performance Qualification to AWS D1.1 (Structural Welding Code - Steel)
American Welding Society (AWS) · Intermediate
Best for: Structural and construction welders working on buildings, bridges, and steel fabrication.
The dominant structural code in the US; passing a D1.1 test plate proves you can weld to the standard most fabricators require.
ASME Section IX Welder Performance Qualification
Qualified by employer to ASME Boiler and Pressure Vessel Code, Section IX · Intermediate
Best for: Welders on pressure vessels, boilers, and process piping.
Required for code work on pressurized equipment; ties you to a specific Welding Procedure Specification, process, and position.
API 1104 Welder Qualification (Welding of Pipelines and Related Facilities)
Qualified to American Petroleum Institute (API) Standard 1104 · Intermediate to Advanced
Best for: Pipeline welders in oil and gas transmission and distribution.
The governing standard for pipeline welding; high demand and strong pay where pipeline work exists.
AWS Certified Welder
American Welding Society (AWS) · Entry to Intermediate
Best for: Welders who want a transferable, third-party verified qualification not tied to one employer.
A recognized national program tested at AWS Accredited Test Facilities, with results recorded in a verifiable registry.
AWS Certified Welding Inspector (CWI)
American Welding Society (AWS) · Advanced
Best for: Experienced welders moving into inspection, quality, or lead roles.
A premium credential that opens higher-paying QA and inspection careers; requires experience plus a demanding exam.
AWS SENSE Entry Welder Certificate
American Welding Society (AWS) SENSE program (via accredited schools) · Entry
Best for: Students and new welders completing a SENSE-aligned training program.
A structured, recognized entry path that signals foundational skills to employers and apprenticeships.
NCCER Welding Certification
National Center for Construction Education and Research (NCCER) · Entry to Intermediate
Best for: Welders in construction and industrial settings, especially where NCCER is the standard.
Widely accepted in construction; credentials are tracked in the NCCER Registry and recognized across many contractors.
AWS Certified Welding Educator (CWE)
American Welding Society (AWS) · Advanced
Best for: Experienced welders who teach or train others in a school or shop.
Validates teaching competency for those moving into instruction and workforce training.
Underwater Welder Certification (AWS D3.6M Underwater Welding Code)
Qualified to AWS D3.6M, typically with commercial dive certification · Advanced
Best for: Commercial divers performing wet or dry hyperbaric welding.
A specialized, high-pay niche; pair the welding qualification with recognized commercial dive training.
Aerospace Welder Qualification to AWS D17.1 (Fusion Welding for Aerospace Applications)
Qualified to AWS D17.1 · Advanced
Best for: Welders in aerospace and high-precision manufacturing.
Required for aerospace fusion welds; demonstrates tight tolerance and quality control skills.
How to choose the right welder certification
Start from the work you want and the code that governs it. Structural and fabrication shops test to AWS D1.1; pressure vessel, boiler, and piping work runs on ASME Section IX; pipeline work uses API 1104. The smartest move is to qualify to the code your target employers actually weld to, in the process and position they need, rather than collecting unrelated certificates.
Match the credential to your stage too. If you are new, a SENSE-aligned school certificate or the AWS Certified Welder program gives you a testable, verifiable starting point. As you gain hours, add code-specific performance qualifications, and if you want to leave the hood behind, the AWS Certified Welding Inspector (CWI) opens inspection and quality roles. Remember that welder qualifications can lapse, so keep current ones documented and retest when a job requires it.
How to list certifications on a welder resume
Be specific. A line like "AWS D1.1 qualified, SMAW and FCAW, 3G and 4G positions, plate" tells a hiring manager far more than "certified welder." For each qualification, list the code or standard, the issuing or qualifying body, the welding process, the position, and the date, plus any material and thickness range. This is exactly what a recruiter and an applicant tracking system search for.
Put your strongest, most job-relevant qualifications in a dedicated Certifications section near the top, and note current status with dates. List in-progress training honestly as "in progress." Never claim a qualification you have not passed, since test records and registries such as the AWS or NCCER databases make it easy to verify and fast to lose an offer over.

Frequently asked questions
What certification do welders need to get hired?
There is no single universal certificate. Most employers want a current welder performance qualification to the code they work to — commonly AWS D1.1 for structural steel, ASME Section IX for pressure work, or API 1104 for pipelines. A SENSE-aligned school certificate or the AWS Certified Welder program is a strong starting point if you are new.
Is welding certification a license?
For most welders it is a qualification, not a government license. You pass a test weld to a written procedure and the result is recorded by an employer, an AWS Accredited Test Facility, or a registry. Some jurisdictions and specialties (for example certain municipal or code-governed work) have additional requirements, so check the local rules for your trade.
How much does an AWS welding certification cost?
It varies by facility and test, but a performance qualification test at an AWS Accredited Test Facility is generally a few hundred dollars per process and position, plus material and retest fees. School-based SENSE programs cost more because they include training. The AWS Certified Welding Inspector (CWI) is significantly more expensive given its seminar and exam.
Which welding certification pays the most?
Specialized and code-heavy qualifications tend to pay best — pipeline welding under API 1104, underwater welding under AWS D3.6M, and aerospace work under AWS D17.1 are well compensated for those who qualify. Moving into inspection with the AWS Certified Welding Inspector (CWI) also raises earning potential.
