- The exam is a 100-scored-question, closed-book knowledge test; 60% is the passing score.
- Equipment Setup, Processes and Schedules, and Welding Procedures each carry 15% of the exam.
- Certification lasts five years and requires reexamination, not continuing-education-only renewal.
What CRWT Certification Actually Is
CRWT stands for Certified Resistance Welding Technician. It is a professional credential for people who set up, operate, troubleshoot and maintain resistance welding equipment: spot welding, seam welding, projection welding and related processes that join metal using electrical current, force and time rather than a consumable arc or filler.
The credential is administered by the American Welding Society (AWS) and was co-developed with the Resistance Welding Manufacturing Alliance (RWMA). That pedigree matters. RWMA's literature is the standard reference in the resistance welding industry, and the exam's reference list reflects it directly. If you have seen "CRWT" attached to other credentials elsewhere, set those aside: this article, and this site, cover only the AWS Certified Resistance Welding Technician program.
If you are looking for shorter definitions of the term, our pages on what CRWT stands for and the meaning of CRWT cover the vocabulary. This article goes further, into how the certification is structured and what it asks of you.
Who Issues It and What the Exam Measures
The certification is governed by AWS QC20:2020, Specification for AWS Certification of Resistance Welding Technicians, while the eligibility rules come from AWS C1.5:2019, Specification for the Qualification of Resistance Welding Technicians. Together they define who may sit for the exam and what the exam covers.
That distinction shapes how you prepare. You will not win points for a steady hand; you will win them for knowing why a schedule produces expulsion, how electrode geometry affects current density, what a peel test tells you, and how to read a welding symbol on a drawing.
How the Exam Is Delivered
The Examination Guide for Certified Resistance Welding Technician (revised January 24, 2025) specifies the delivery details. Here is the format at a glance:
| Feature | CRWT Exam Detail |
|---|---|
| Delivery | Computer-based at a Prometric test center |
| Scored questions | 100 |
| Unscored pretest questions | 10 |
| Question style | Multiple choice, single correct answer |
| Testing time | 135 minutes |
| Appointment length | 150 minutes |
| Passing score | 60% |
| Reference materials | Closed book |
| Calculator | Nonprogrammable scientific, construction or four-function permitted |
| Scratch work | Scratch paper and pencil provided |
Details that catch candidates off guard
- The appointment is not the timer. You have 150 minutes in the center but 135 minutes of actual testing. The remainder covers check-in and orientation.
- There is no scheduled break. If you step away, the unscheduled break consumes your examination time.
- You cannot identify the unscored items. The 10 pretest questions are mixed in, so treat every question as if it counts.
- The 60% figure is a passing requirement, not a pass rate. We have not verified a current cohort pass rate. For more on this distinction, see our breakdown of the CRWT passing score and our discussion of what the data does and does not show in CRWT pass rate.
The guide's exam references are worth knowing by name, because they signal where question content originates: AWS C1.1M/C1.1:2019, the RWMA Resistance Welding Manual (revised fourth edition, 2013), the AWS Resistance Welding Pocket Handbook (2011) and AWS A2.4:2020 (the welding symbols standard).
The Nine Exam Domains
QC20:2020 clause 6.2 lists nine content domains with percentage weights. These are exam objectives, not recommended training-hour allocations, so use them to understand where questions come from rather than as a rigid time budget.
| Domain | Weight |
|---|---|
| Weld Equipment Setup including Machine/Tooling Design | 15% |
| Welding Processes and Schedules | 15% |
| Welding Procedures | 15% |
| Materials | 13% |
| Weld Quality and Testing including Destructive and Non-destructive | 12% |
| Maintenance | 12% |
| Definitions and Terminology | 10% |
| Conversion and Calculations | 5% |
| Welding Symbols | 3% |
Weld Equipment Setup including Machine/Tooling Design (15%)
This is where hands-on knowledge of the machine and its tooling gets tested in written form.
- Machine types and what distinguishes them in practice
- Electrode holders, tip and wheel geometry, and fixturing
- How tooling design influences current path and force application
Welding Processes and Schedules (15%)
Expect questions about how a weld schedule's parameters interact and what happens when one is wrong.
- The relationship among current, time and force
- Squeeze, weld, hold and off time in a schedule
- Recognizing process-specific behavior in spot, seam and projection welding
Welding Procedures (15%)
This domain covers the "how it is done in production" side: documented procedures and the discipline of following them.
- Establishing and verifying a procedure for a given joint
- Adjusting a procedure when a symptom appears
- Connecting procedure steps to the quality outcome they protect
Materials (13%)
Materials behave very differently under resistance heating, and the exam rewards candidates who know why.
- How base-metal properties affect weldability
- The effect of coatings and surface conditions
- Why dissimilar or high-conductivity materials demand different approaches
Weld Quality and Testing including Destructive and Non-destructive (12%)
Knowing a weld is good requires knowing how to test it and how to read the result.
- Destructive methods and what a failure mode reveals
- Non-destructive evaluation and its limits
- Linking a defect back to its probable cause
Maintenance (12%)
Equipment that drifts out of condition produces drifting weld quality.
- Electrode care, dressing and replacement logic
- Cooling systems and their role in consistency
- Routine checks that catch problems before scrap appears
The three smaller domains, Definitions and Terminology (10%), Conversion and Calculations (5%) and Welding Symbols (3%), are easy to underestimate. Terminology underpins every other domain, since a misread term misreads the question. Calculations are a small slice but are among the most mechanical, point-earning items on the exam, and the permitted calculator makes them very winnable. Symbols are only 3%, but they are highly learnable from AWS A2.4:2020. For a deeper walk through each area, see our complete guide to the CRWT exam domains.
Eligibility Routes Under AWS C1.5
Clause 5.1 of AWS C1.5:2019 sets three routes to qualify. Each requires verifiable documentation:
- Education plus experience: a high-school diploma, GED or equivalent, plus one year of relevant resistance-welding machinery experience.
- Post-secondary route: a post-high-school or post-GED graduate, plus six months of relevant experience.
- Experience in place of education: three years of relevant experience substituting for the education requirement.
Self-employed and contract applicants can evidence their experience with two separate client reference letters, or with the specified affidavit alternative. That is a practical point for independent maintenance contractors, who often lack a traditional employer to sign off.
Our CRWT requirements guide covers eligibility in more depth, including how to document experience cleanly.
Fees and Registration Mechanics
The AWS Certification & Education Programs Price List, effective January 1, 2026, sets the following CRWT figures:
| Item | AWS Member | Nonmember |
|---|---|---|
| Examination | $445 | $590 |
| Seminar-and-exam package | $1,035 | $1,355 |
| Retest | $235 | $235 |
| Recertification by examination | $445 | $590 |
Two fine-print items deserve attention. First, Student and Early-Career memberships do not qualify for member pricing. Second, the nonmember prices do not include the cost of membership, so if you are weighing whether to join AWS to capture the lower rate, price the membership separately and compare. Preparatory training is optional; the seminar-and-exam package is a convenience, not a requirement.
For a fuller view of what a certification attempt costs end to end, see our CRWT certification cost breakdown, and if you are trying to pin down timing, our guide to CRWT exam dates and scheduling explains how Prometric appointments fit in.
The Five-Year Cycle and Reexamination
CRWT certification lasts five years, and maintaining it requires reexamination under QC20:2020 and the current AWS program page. It is not a continuing-education-only renewal. Some older qualification-maintenance language in C1.5 may suggest a different path, but it does not replace the AWS certification rule, so plan for retaking the exam when your cycle ends.
If you do not pass, QC20 permits up to three reexaminations within one year of the original test, with the retest fee listed above. That gives you a structured second chance without starting the whole application over, though each attempt costs money and should be earned by targeted review rather than simple repetition.
Key Takeaway
Budget for the second exam on day one. Because renewal is by reexamination, the knowledge you build now has a five-year shelf life. Keep your reference materials and notes organized so the next cycle is a refresh, not a restart.
Who Hires and Who Benefits
Resistance welding is the workhorse joining method in industries that produce sheet-metal assemblies at volume. The people most likely to benefit from the credential include:
- Maintenance and process technicians in manufacturing plants who keep welding cells running and consistent.
- Setup technicians and lead operators who build and adjust weld schedules for new part numbers.
- Quality technicians who evaluate weld samples and trace defects back to equipment or schedule causes.
- Field and service technicians who work for welding equipment suppliers and need credibility with customers.
- Independent contractors who sell maintenance and troubleshooting expertise to multiple plants.
Automotive and appliance manufacturing, metal fabrication, and equipment suppliers are typical settings where resistance welding know-how is valued, though specific hiring practices vary by employer. We do not quote salary figures in this overview, because compensation depends heavily on region, industry and role; our analyses of CRWT earnings and whether the certification is worth it take that up in context, and our page on CRWT jobs looks at the roles themselves.
Sequencing Your Preparation
Preparation is optional, but most candidates benefit from structure. Rather than studying in the order the domains appear, sequence by dependency: terminology and materials come first because they unlock the rest, and the heavily weighted setup, process and procedure domains follow once the vocabulary is secure.
Vocabulary and Materials
- Work through Definitions and Terminology (10%) using the RWMA manual and the Pocket Handbook
- Study Materials (13%): conductivity, coatings and weldability
Equipment and Processes
- Weld Equipment Setup including Machine/Tooling Design (15%)
- Welding Processes and Schedules (15%): practice reading how current, time and force interact
Procedures, Quality and Maintenance
- Welding Procedures (15%)
- Weld Quality and Testing (12%) and Maintenance (12%): pair symptoms with causes
Calculations, Symbols and Practice
- Conversion and Calculations (5%) with your permitted calculator type
- Welding Symbols (3%) via AWS A2.4:2020
- Timed practice under the 135-minute limit using the CRWT practice tests
Treat this as a template to adjust, not a prescription; someone with years on the shop floor may compress the equipment weeks and spend longer on terminology and symbols, while a newer technician may need the opposite. Our CRWT study guide goes deeper on resources, and the CRWT cheat sheet is useful for last-week review. To gauge how demanding the test feels, read how hard the CRWT exam is, then check yourself with a few sessions on the main practice test site.
