- The CRWT is an AWS knowledge examination, co-developed with RWMA; it is not a hands-on welding performance test.
- The exam has 100 scored plus 10 unscored questions, 135 testing minutes, and a 60% passing score.
- Equipment Setup, Processes and Schedules, and Procedures each carry 15% of the exam.
- Certification lasts five years and renews by reexamination, not continuing-education credits alone.
What the CRWT Credential Actually Is
The Certified Resistance Welding Technician credential is issued by the American Welding Society (AWS) and was co-developed with the Resistance Welding Manufacturing Alliance (RWMA). It recognizes technicians who understand how resistance welding equipment is set up, scheduled, run, tested and maintained. The exam objectives come from AWS QC20:2020, Specification for AWS Certification of Resistance Welding Technicians, while the eligibility rules trace to AWS C1.5:2019, Specification for the Qualification of Resistance Welding Technicians.
One point trips up a lot of candidates: this is a knowledge examination. You will not be asked to run a spot welder or pull a nugget on test day. You will be asked to apply knowledge about electrodes, weld schedules, materials, testing and troubleshooting through multiple-choice questions. If you are new to the acronym itself, the background articles on what CRWT certification is and what CRWT stands for cover the basics.
Who Qualifies to Sit for the Exam
AWS C1.5:2019, clause 5.1, sets three alternative eligibility paths. You need to satisfy only one of them:
| Path | Education | Relevant Experience |
|---|---|---|
| Standard | High-school diploma, GED or equivalent | One year working with resistance-welding machinery |
| Post-secondary graduate | Post-high-school or post-GED graduate | Six months |
| Experience-only | Education requirement waived | Three years of relevant experience |
Documentation matters. AWS requires verifiable education and experience records, so gather diplomas, transcripts, employer letters and supervisor contacts before you start the application. Self-employed and contract technicians have a workable route: two separate client reference letters, or the specified affidavit alternative, can serve as experience evidence.
The visual-acuity question
Here is a genuine source conflict worth knowing about. The current AWS CRWT program page and the undated step-by-step pathway document both mention a visual-acuity form. However, the AWS Visual Acuity Form dated September 19, 2025 states that it applies only to SCWI, CWI, CAWI, CRI and CWEng applications, and it does not list CRWT. Do not assume another credential's vision standard applies to you. Contact AWS and confirm what your CRWT application actually requires before you submit.

Exam Format: What Test Day Looks Like
The Examination Guide for Certified Resistance Welding Technician, revised January 24, 2025, specifies computer-based delivery at Prometric test centers. The key parameters:
- Questions: 100 scored plus 10 unscored pretest questions, all single-correct-answer multiple choice.
- Time: 135 minutes of testing inside a 150-minute appointment. The appointment length is not your timer.
- Passing score: 60%.
- Closed book: No reference materials are permitted.
- Calculators: Nonprogrammable scientific, construction and four-function models are permitted. Scratch paper and a pencil are provided.
- Breaks: None scheduled. An unscheduled break consumes examination time.
You cannot tell which 10 questions are unscored, so treat every item as if it counts. At 135 minutes for 110 questions, you have roughly 1.2 minutes per question on average, which is comfortable for recall items but tight for multi-step calculations. Pace accordingly: bank time on definitions and terminology, then spend it on calculation and schedule problems.
The Nine Domains and What Each Demands
The nine exam domains and their weights are published in QC20:2020, clause 6.2. These are exam objectives, not recommended training allocations, but they are the best guide to where points live. Three domains tie for the heaviest weight at 15% each. For a deeper breakdown, read the complete guide to all nine CRWT content areas.
| Domain | Name | Weight |
|---|---|---|
| 1 | Weld Equipment Setup including Machine/Tooling Design | 15% |
| 2 | Welding Processes and Schedules | 15% |
| 3 | Weld Quality and Testing including Destructive and Non-destructive | 12% |
| 4 | Definitions and Terminology | 10% |
| 5 | Welding Symbols | 3% |
| 6 | Materials | 13% |
| 7 | Conversion and Calculations | 5% |
| 8 | Welding Procedures | 15% |
| 9 | Maintenance | 12% |
Domain 1: Weld Equipment Setup including Machine/Tooling Design (15%)
Expect questions on how a resistance welding machine is configured and how tooling shapes the weld.
- Electrode and tooling geometry, holders and fixturing
- Machine components, force systems and power supply considerations
- How design choices affect current path, heat balance and repeatability
Domain 2: Welding Processes and Schedules (15%)
This domain covers the resistance welding process family and the schedule parameters that control it.
- Spot, projection, seam and related resistance processes
- Squeeze, weld, hold and off timing, plus current and force relationships
- How schedule changes alter nugget formation and expulsion risk
Domain 3: Weld Quality and Testing (12%)
Know how welds are evaluated and what the results tell you.
- Destructive methods such as peel and chisel tests, and what the failure mode indicates
- Non-destructive evaluation and visual inspection criteria
- Linking a defect to its probable process cause
Domain 6: Materials (13%)
Material behavior drives weldability, and this is the largest of the middle-weight domains.
- How resistivity, conductivity and thermal properties affect heat generation
- Coated and uncoated steels, aluminum and other commonly joined metals
- Surface condition and its effect on contact resistance
Domain 8: Welding Procedures (15%)
Procedures tie your knowledge to disciplined, documented practice.
- Establishing, qualifying and following written procedures
- Setup verification, process monitoring and adjustment logic
- Responding to variation without compromising weld integrity
Domain 9: Maintenance (12%)
Preventive upkeep is a recurring exam theme.
- Electrode dressing and replacement, cooling system care
- Inspecting and servicing equipment components
- Recognizing wear-related symptoms before they become weld defects
The smaller domains are easy to neglect and costly to ignore. Definitions and Terminology (10%) rewards plain memorization, Conversion and Calculations (5%) rewards practice with a permitted calculator, and Welding Symbols (3%) is brief but usually quick points once you learn the conventions. Together, Domains 4, 5 and 7 account for 18% of the exam.
Fees, Retests and Registration Mechanics
The AWS Certification & Education Programs Price List, effective January 1, 2026, lists these CRWT prices:
| Item | AWS Member | Nonmember |
|---|---|---|
| Examination fee | $445 | $590 |
| Seminar-and-exam package | $1,035 | $1,355 |
| Retest | $235 | $235 |
| Recertification by examination | $445 | $590 |
Two details deserve attention. First, Student and Early-Career memberships do not qualify for member pricing. Second, the nonmember figures do not include the cost of membership, so if you plan to join AWS to capture the lower rate, add the membership fee to your comparison. Preparatory training is optional; the seminar package is a convenience, not a requirement. Verify current figures against the AWS price list before paying, since fees can change. Our CRWT certification cost breakdown works through the full budget, and CRWT exam dates and scheduling covers booking logistics.
Retest rules
QC20 permits up to three reexaminations within one year of the original test. Because the retest fee is lower than the initial exam fee, a failed attempt is recoverable, but it still costs time and money. That is a good reason to prepare thoroughly the first time rather than treating the first sitting as a trial run.
The Reference Library Behind the Questions
The Examination Guide lists the documents that exam content draws from. Build your study around these editions, because older printings may differ:
- AWS C1.1M/C1.1:2019, the recommended practices for resistance welding
- RWMA Resistance Welding Manual, revised fourth edition, 2013
- AWS Resistance Welding Pocket Handbook, 2011
- AWS A2.4:2020, the standard symbols for welding, brazing and nondestructive examination
Note that A2.4 maps directly to the small Welding Symbols domain, while the RWMA manual and C1.1 supply most of the process, equipment, materials and maintenance content. The pocket handbook is a good fast-lookup companion once you have read the longer documents. Because the exam is closed book, the goal is internalizing these sources, not carrying them in. For structured preparation options, see our overview of CRWT training.
Key Takeaway
Match your study materials to the edition years in the Examination Guide. Studying from an outdated manual risks learning terminology or practices that the current exam no longer reflects.
A Domain-Weighted Prep Sequence
Rather than generic scheduling, order your preparation by weight and by how domains build on one another. Materials and terminology underpin nearly everything else, so start there; the heaviest applied domains come next while the foundations are fresh. The full methodology lives in the CRWT study guide, and this is a CRWT-specific skeleton you can adapt.
Foundations: Terminology and Materials
- Domain 4 vocabulary and Domain 6 material behavior
- Resistivity, contact resistance and coating effects
Equipment and Processes
- Domain 1 setup and tooling design
- Domain 2 process types and schedule parameters
Procedures, Quality and Maintenance
- Domain 8 procedures and Domain 3 testing and defect causes
- Domain 9 preventive maintenance routines
Small Domains and Timed Practice
- Domain 7 calculations using a permitted calculator, Domain 5 symbols
- Full-length practice under the 135-minute limit
Use the CRWT practice tests in the final week to rehearse pacing across all 110 questions, and use your misses to decide which domain gets extra attention. If you want a condensed refresher, the CRWT cheat sheet collects must-know facts, and how hard the CRWT exam is sets realistic expectations about difficulty.
The Five-Year Cycle and Reexamination
CRWT certification lasts five years. Under QC20:2020 and the current AWS program page, maintaining it requires reexamination, not continuing-education credit alone. The older C1.5 qualification-maintenance language should not be used in place of this AWS certification rule. Recertification by examination is priced at $445 for members and $590 for nonmembers.
That five-year horizon shapes the value calculation. You are not paying once for a permanent credential; you are committing to periodic demonstration of current knowledge. Whether that trade-off pays off depends on your role and employer, which is explored in Is the CRWT Certification Worth It? Pay expectations are covered in the CRWT salary guide, and typical roles in CRWT jobs. Resistance welding is concentrated in manufacturing environments that run spot, projection and seam operations at volume, which is where technicians with this credential tend to be most relevant.
Frequently Asked Questions
No. It is a computer-based, closed-book knowledge examination delivered at Prometric test centers. It measures understanding of resistance welding equipment, processes, materials, testing and maintenance rather than your ability to produce a weld.
The exam contains 100 scored questions plus 10 unscored pretest questions, all single-correct-answer multiple choice. You get 135 minutes of testing within a 150-minute appointment, and there is no scheduled break.
The passing score is 60%. That is the required cut score, not a measured pass rate; a current cohort pass rate has not been verified, so avoid sources that present one as fact.
Per the AWS price list effective January 1, 2026, the exam is $445 for AWS members and $590 for nonmembers. Retests cost $235 for either group. Student and Early-Career memberships do not qualify for member pricing, and nonmember prices do not include membership.
Certification lasts five years and is renewed by reexamination, not by continuing-education credits alone. Recertification by examination costs $445 for members and $590 for nonmembers. Confirm current terms on the AWS program page before you plan your renewal.
