AWS Welding Certification Practice Test

The AWS Welding Certification Practice Test is a free intermediate-level, 20-minute skill test from Science of Apps. It tests the written knowledge behind American Welding Society certifications such as Certified Welder and the Certified Welding Inspector (CWI) fundamentals exam — welding processes and metallurgy, welding symbols, joints and positions, discontinuities, inspection and testing, and codes, procedures and safety — written to AWS A2.4 symbols, AWS D1.1 Structural Welding Code – Steel, ASME Section IX, ANSI Z49.1 and TWI technical guidance for 2026. Practical weld tests cannot be done online. Score 70% or more on its 20 questions to earn a verifiable AWS Welding Readiness certificate (SOA-AWSW). Every question is based on published standards and research — including AWS certification programs (Certified Welder, CWI) and AWS D1.1 Structural Welding Code – Steel (American Welding Society), Technical knowledge FAQs on welding processes, defects and inspection (TWI), ASME BPVC Section IX: Welding, Brazing and Fusing Qualifications (ASME) — and each answer is explained with its source.

Yes. Science of Apps has a free AWS Welding Certification Practice Test built on the current American Welding Society exam outline for 2026 and 2027. It covers welding processes and metallurgy, welding symbols, joints and positions, discontinuities, inspection and testing and codes, procedures and safety, scores you instantly and issues a verifiable certificate.

Read the four skill areas on this page, then take the 20-minute test online — no fee, course or sign-up. You see every answer explained when you finish. Score 70% or more and you get a AWS Welding Readiness certificate straight away, on screen, as a PDF and by email, with a credential ID anyone can verify.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: AWS certification programs (Certified Welder, CWI) and AWS D1.1 Structural Welding Code – Steel (American Welding Society); Technical knowledge FAQs on welding processes, defects and inspection (TWI); ASME BPVC Section IX: Welding, Brazing and Fusing Qualifications (ASME); AWS safety and health fact sheets (with ANSI Z49.1 Safety in Welding, Cutting and Allied Processes) (American Welding Society). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Four skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Welding Processes and Metallurgy (Arc processes, Filler metals and Heat and metallurgy); Welding Symbols, Joints and Positions (AWS A2.4 symbols, Joint types and Test positions); Discontinuities, Inspection and Testing (Weld discontinuities, NDT methods and Destructive tests); Codes, Procedures and Safety (WPS, PQR and welder qualification, Codes and Safety). Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

Welder or welding apprentice, Welding inspector or CWI candidate, Fabrication supervisor, Welding engineering technician and Quality inspector in fabrication. It suits anyone who wants a quick, verifiable way to show AWS Welding Certification knowledge in 2026 and 2027, from students and career switchers to experienced professionals.

For the AWS Certified Welder programme you pass a hands-on weld test at an AWS Accredited Test Facility, to a code such as D1.1 or API 1104. For the Certified Welding Inspector (CWI) you need qualifying experience and must pass three exams: Fundamentals, Practical and a code-book exam.

A Welding Procedure Specification (WPS) is the written instruction welders follow. A Procedure Qualification Record (PQR) records the actual test weld and the test results that prove the WPS produces sound welds.

No. It is an independent practice test written to the publicly available AWS Welding Certification content outline for 2026 and 2027, for checking your readiness before you book the real exam. Passing earns a Science of Apps certificate rather than the official credential.

Yes. The test is online, in English and free everywhere — people take it from India, the US, the UK, Europe, Africa, Latin America and Asia-Pacific. Your certificate is dated with your own local date and can be verified from anywhere at scienceofapps.com/certification/verify/.

20 questions — 5 from each of 4 skill areas — with a 20-minute limit. You need 70% (14 of 20) to pass and 90% for distinction.

We rate it Intermediate: assumes hands-on experience in the role. It has 20 scenario questions — 5 from each of 4 skill areas — and a 20-minute limit. You need 70% (14 of 20) to pass and 90% for distinction.

Nothing. There is no fee to take a test, to receive the certificate, to have it emailed or to verify it, and no sign-up.

On our server, not in your browser. The answers never reach the page until you submit, so a certificate can only be earned by passing. Each certificate gets a unique credential ID stored by Science of Apps.

You see your score for each area and every question with the correct answer and why, with the published source behind it. You can retake after 30 minutes, and the retake draws questions you haven't seen yet.

No. Every certificate is dated, so it always shows when you passed. Retake a test any time for a newer date or a higher score.

Yes. After you pass, Add to LinkedIn opens the Licenses & certifications form with the certificate name, Science of Apps as the issuer, the issue date, your credential ID and the verification link filled in. You can also download it as a PDF or PNG, and it's emailed to you as a PDF.

Every certificate has a credential ID and a QR code. Scanning it, or entering the ID at scienceofapps.com/certification/verify/, shows the holder's name, the certification, the score and the issue date from our records.

No. They are Science of Apps' own assessments of applied skill. They aren't issued by a university or standards body, and they work best alongside a portfolio that shows the skills in real work.
