The Short Answer: A CRWT Is a Credentialed Resistance Welding Technician
A CRWT is a Certified Resistance Welding Technician: a person who has met American Welding Society (AWS) eligibility requirements and passed AWS's knowledge examination covering resistance welding equipment, processes, materials, quality, and maintenance. The acronym also circulates in other industries, so it is worth being precise. On this site, and throughout this article, CRWT refers only to the AWS resistance welding credential.
Resistance welding joins metal by passing electrical current through the parts while force holds them together. The resistance at the interface generates heat, and the heat forms the weld. Spot welding on automotive body panels is the most familiar example, but the family also includes seam, projection, and flash or upset processes. A CRWT demonstrates, through examination, that they understand how these systems are set up, scheduled, run, inspected, and kept in working order.
If you are earlier in your research, our related explainers cover the same ground from different angles: What Is CRWT Certification? and What Does CRWT Stand For? This article focuses on what the credential is, how it is earned, and what it actually tests.
Who Issues the Credential and Why That Matters
The credential is issued by the American Welding Society and was co-developed with the Resistance Welding Manufacturing Alliance (RWMA). That pairing is meaningful. AWS is the standards and certification body most welding professionals already recognize, while the RWMA is the trade organization focused specifically on resistance welding equipment and practice. The result is an examination anchored in both formal standards and shop-floor reality.
Two AWS documents define the program's structure:
- AWS QC20:2020, Specification for AWS Certification of Resistance Welding Technicians, which sets out the exam domains and their percentage weights (clause 6.2).
- AWS C1.5:2019, Specification for the Qualification of Resistance Welding Technicians, which sets out the education and experience eligibility routes (clause 5.1).
What a CRWT Actually Works On
The exam domains are a good proxy for the job itself. A resistance welding technician sits at the junction of machine, material, and process, and the work typically spans several tasks.
Machine and tooling work
Technicians set up welding machines, select and dress electrodes, and understand how tooling geometry, alignment, and fixturing affect weld quality. When parts are being welded inconsistently, equipment and tooling are the first places to look.
Schedules and procedures
A weld schedule defines the variables that govern a weld, such as current, weld time, and electrode force, along with the sequencing around them. The exam separates Welding Processes and Schedules from Welding Procedures, and candidates should be comfortable with both the process-level logic and the documented, repeatable way a weld is actually produced on the floor.
Quality and troubleshooting
When a weld fails inspection, a technician needs to read the evidence. That means knowing the destructive and non-destructive methods used to evaluate welds, and connecting what you see (undersized nuggets, expulsion, surface marking) back to a likely cause in the setup or material.
Preventive maintenance
Cooling, electrical connections, air and force systems, and electrode condition all drift over time. Maintenance carries real weight on the exam because it reflects real downtime and real scrap.
How the Knowledge Examination Works
The format below comes from the AWS Examination Guide for Certified Resistance Welding Technician (revised January 24, 2025).
| Feature | CRWT Examination Detail |
|---|---|
| Delivery | Computer-based at a Prometric test center |
| Scored questions | 100 |
| Unscored pretest questions | 10 additional questions mixed in |
| Testing time | 135 minutes |
| Appointment length | 150 minutes (includes check-in and administrative time) |
| Question type | Multiple choice, single correct answer |
| Passing score | 60% |
| Reference materials | Closed book |
| Calculators | Nonprogrammable scientific, construction, and four-function calculators permitted |
| Scratch work | Scratch paper and pencil provided |
| Breaks | None scheduled; an unscheduled break uses exam time |
Details candidates often miss
- The 150-minute appointment is not your timer. You get 135 minutes of actual testing. Plan pacing around the shorter number.
- Ten questions do not count. The unscored pretest items are indistinguishable from the rest, so treat every question seriously.
- There is no scheduled break. If you step away, the clock does not stop.
- The calculator matters. The Conversion and Calculations domain is small, but a few unit-conversion and arithmetic questions are easy points if you are practiced.
For a plain-language look at the cut score, see CRWT Passing Score 2026. Note that 60% is the passing requirement, not a pass-rate statistic. A current cohort pass rate has not been verified, which is discussed in CRWT Pass Rate 2026: What the Data Shows.
The Nine Exam Domains and Their Weights
The nine domains and their percentage weights come from AWS QC20:2020, clause 6.2. They are exam objectives, which describe how the test is built, not an editorial recommendation for how many hours to spend on each topic.
| 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% |
The Three 15% Domains
Equipment Setup, Processes and Schedules, and Procedures together account for 45% of the exam. They overlap in practice, which is good news: learning how a machine is configured helps you reason about schedules, and understanding schedules helps with procedures.
- Machine and tooling design, including how electrode and fixture choices affect the weld
- How weld variables interact within a schedule
- How a documented procedure turns a schedule into repeatable production
Materials (13%)
Different metals respond very differently to resistance welding because electrical and thermal behavior, coatings, and surface condition all change the heat balance.
- How base-metal properties influence weldability
- The effect of coatings and surface condition on weld behavior
- Why the same schedule cannot simply be reused across materials
Weld Quality and Testing (12%) and Maintenance (12%)
These two domains are the troubleshooting half of the job. Quality tells you something went wrong; maintenance knowledge tells you where to look.
- Destructive versus non-destructive evaluation methods
- Reading failure evidence back to its likely cause
- Routine upkeep of cooling, electrical, and force systems and electrodes
Terminology, Calculations, and Symbols (18% combined)
These are the smallest domains and the cheapest to master. Definitions and Terminology is 10% on its own; Conversion and Calculations is 5%; Welding Symbols is 3%. Because the exam is closed book, vocabulary and symbol recognition need to be memorized, not looked up.

The reference editions behind the questions
The Examination Guide lists the documents the exam draws from. Knowing their names helps you evaluate any study material you pick up:
- AWS C1.1M/C1.1:2019
- RWMA Resistance Welding Manual, revised fourth edition, 2013
- AWS Resistance Welding Pocket Handbook, 2011
- AWS A2.4:2020 (the welding symbols standard)
If a study resource cites older or unrelated editions, treat its details with caution.
Who Can Apply
Eligibility follows AWS C1.5:2019, clause 5.1. There are three routes:
- A high-school diploma, GED, or equivalent, plus one year of relevant resistance welding machinery experience.
- A post-high-school or post-GED graduate route, plus six months of relevant experience.
- Three years of relevant experience in place of the education requirement.
Education and experience must be documented in a verifiable way. Self-employed and contract applicants can satisfy the experience requirement with two separate client reference letters or the specified affidavit alternative.
Our full walkthrough is in CRWT Requirements 2026: Eligibility, Prerequisites & How to Qualify. Preparatory training is optional, so you do not need to complete a seminar to sit for the exam.
Fees, Retests, and Membership Pricing
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 pricing details deserve attention. First, Student and Early-Career memberships do not qualify for member pricing. Second, the nonmember prices above do not include the cost of membership itself, so anyone weighing membership against the nonmember premium should price it separately. The full cost picture, including what the seminar package buys you, is in CRWT Certification Cost 2026: Complete Pricing Breakdown.
The Five-Year Cycle and Reexamination
A 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. Older qualification-maintenance language in C1.5 should not be read as overriding this certification rule.
QC20 also permits up to three reexaminations within one year of the original test. Given the $235 retest fee for either membership category, a failed first attempt is a setback but not a dead end. Budget for the possibility, and use your score report to concentrate your second round on the domains that cost you the most.
Where the Credential Gets Used
Resistance welding is a production process, so the people who need CRWT-level knowledge tend to work wherever metal parts are joined at volume. Typical settings include:
- Automotive and automotive-supplier plants, where spot welding of body structures and components is central.
- Appliance and metal-fabrication manufacturers, which rely on spot, projection, and seam welding for enclosures and assemblies.
- Welding equipment makers and distributors, where technicians support installation, training, and service.
- Maintenance and process-engineering teams inside any plant running resistance welding lines.
The credential serves as a portable, third-party signal of competence. It does not guarantee a particular title or wage, and no specific salary figure is claimed here. For earnings and market context, see CRWT Salary Guide 2026, CRWT Jobs, and Is the CRWT Certification Worth It?
Key Takeaway
Think of the CRWT as proof of applied understanding. Employers who run resistance welding lines care about whether you can set up, diagnose, and maintain the process. The exam is built to reflect that.
Sequencing Your Preparation Around the Weights
A good preparation plan follows the structure of the exam rather than a generic calendar. Here is one way to order the work, using the domain weights as the rationale.
Vocabulary, Symbols, and Calculations
- Memorize terminology early; it is closed book and underpins every other domain.
- Learn AWS A2.4:2020 symbol conventions, a small 3% domain that is quick to secure.
- Practice unit conversions with a permitted nonprogrammable calculator.
The 45% Core
- Work through Equipment Setup, Processes and Schedules, and Procedures together, since they build on each other.
- Use the RWMA Resistance Welding Manual as your primary reference.
Materials, Quality, and Maintenance
- Connect material behavior to schedule choices.
- Practice working backward from a weld defect to its probable cause.
Timed Practice
- Run full-length sessions against the 135-minute limit, with no breaks.
- Review misses by domain and revisit the weakest ones.
For a fuller plan, see the CRWT Study Guide 2026, and keep the CRWT Cheat Sheet handy for last-minute review. If you are wondering how demanding the exam is, How Hard Is the CRWT Exam? gives an honest read. When you are ready to test yourself under realistic conditions, the CRWT practice test is the place to start, and the full practice question bank lets you drill by domain.
