What You Need to Know About Getting a California Welding Contractor License
A California welding contractor license — known as the C-60 classification — is required by the Contractors State License Board (CSLB) for any business performing welding work on projects valued at $1,000 or more in California. Here is a quick overview of what it takes to get one:
- Be at least 18 years old and have a valid SSN or ITIN
- Have 4 years of journey-level welding experience
- Submit a CSLB application with a $450 fee
- Pass two exams: the Law and Business exam and the C-60 Trade exam
- Complete post-approval steps: Live Scan fingerprinting, contractor’s bond, and workers’ compensation insurance
California does not issue a state license to individual welders. But if you want to run a welding contracting business — even as a sole owner — you need a C-60 license. Without it, you cannot legally take on welding contracts above $1,000.
The process has real moving parts: experience documentation, closed-book exams, bonding, and more. It can feel overwhelming if you don’t know what to expect.
I’m Phil Cocciante, and I spent five years as a license application technician at the CSLB before founding Contractors License Guru — I’ve helped thousands of contractors navigate the exact California welding contractor license process you’re about to start. In this guide, I’ll walk you through every step so you can move forward with confidence.
Understanding the C-60 Welding Contractor Classification
In California construction, the CSLB divides work into various “buckets” or classifications. The California welding contractor license, officially designated as the C-60, has a very specific legal definition. According to the California Code of Regulations, a welding contractor is someone who causes metals to become permanently attached, joined, and fabricated through the use of gases and electrical energy. This process creates temperatures of sufficient heat to perform the thermal joining of metals.
While that sounds like a mouthful, it essentially means if your primary business is fusing metal together using heat—whether via MIG, TIG, Stick, or Flux-core—you fall under this category. It’s important to distinguish this from other similar trades. We often see applicants confused about whether they need a C-60 or something else.
For example, if you are strictly building the skeleton of a skyscraper, you might actually need a C-51 Structural Steel Contractor license. If you are making decorative railings and gates, you might look at the C-23 Ornamental Metal Contractor classification.
| Classification | Primary Focus | Key Difference |
|---|---|---|
| C-60 Welding | Permanent joining and fabrication of metals using heat. | Focuses on the process of welding across various industries. |
| C-51 Structural Steel | Fabrication and erection of structural steel shapes and plates. | Specific to the load-bearing structures of buildings. |
| C-23 Ornamental Metal | Non-structural, decorative metal work like fences and balconies. | Focuses on the aesthetic and safety features of metal. |

How to Obtain Your California Welding Contractor License
Obtaining your California welding contractor license is a marathon, not a sprint. The state of California wants to ensure that anyone running a business and performing potentially dangerous work has the “chops” to do it safely and correctly.
First, let’s talk about the baseline “must-haves.” You must be at least 18 years old. You also need a valid Social Security Number (SSN) or an Individual Taxpayer Identification Number (ITIN). Gone are the days when you could fly under the radar; the CSLB checks these against state records.
The biggest hurdle for most is the experience requirement. You need to prove that you have at least four years of journey-level experience within the last ten years. “Journey-level” means you can perform the work without supervision—you aren’t a helper or an apprentice anymore; you are the one the boss trusts to get the job done right the first time.
If you’re wondering if your specific background counts, our guide on How to Get a Contractors License in California breaks down the general entry requirements in even more detail. You can also find occupational license information for welding contractor in the US to see how California’s standards compare to the rest of the country.
Documenting Your California Welding Contractor License Experience
When you fill out your application, you can’t just say “I’ve been welding for a while.” The CSLB requires a detailed “Work Experience” section. This must be verified by a qualified individual—usually a former employer, a fellow licensed contractor, or a union representative who has first-hand knowledge of your skills.
Here is what we recommend for documenting your four years:
- Be Specific: Instead of saying “welded metal,” say “performed SMAW and TIG welding on structural components and pressure vessels.”
- Quantify Your Time: Ensure the dates you provide add up to 48 months of full-time work.
- Education Credits: Did you go to a trade school? You might be able to get up to three years of credit for a relevant degree or certificate, but you will always need at least one year of actual field experience.
In some rare cases, you might qualify for an exam waiver. For instance, if you’ve been a “qualifier” on another license in good standing for five of the last seven years, you might skip the test. You can read the official 7065.1 Waiver provisions to see if you fit the criteria.
The CSLB application processing team is very thorough. If your experience looks thin or “fluffed,” they will return it for clarification, which can add months to your wait time.
Mastering the California Welding Contractor License Examinations
Once your application is approved, it’s time to face the exams. To get your California welding contractor license, you must pass two separate tests:
- The Law and Business Exam: This covers everything from labor laws and safety (Cal/OSHA) to bookkeeping, contracts, and mechanics liens. It’s the “business” side of being a boss.
- The C-60 Trade Exam: This is all about the sparks and metal. It covers five major areas:
- Planning and Estimating
- Welding Preparation
- Welding, Brazing, and Soldering
- Cutting Processes
- Safety (Trade-specific)
These exams are closed-book and taken on a computer at one of the state’s testing centers. You won’t be able to bring your AWS handbook in with you! This is where many great welders fail—they know how to weld, but they haven’t brushed up on the technical terminology or the specific California laws.
We highly suggest using a C60 welding contractors license study kit and a law and business contractors exam study kit to prepare. Don’t wing it. The state charges a re-exam fee if you fail, and it delays your license. For more tips on the testing environment, visit our page on CSLB Exam Preparation.
The Step-by-Step Application and Fee Process
Let’s talk about the “damage” to your wallet. Getting licensed isn’t free, but it’s an investment in your future earning potential.
As of 2024, the application for original contractor license fee is $450. This fee is non-refundable and covers the processing of your application and your first exam attempt.
Once you pass your exams, you aren’t done yet. You’ll need to pay an initial license fee. For a sole owner, this is currently $200 for a two-year period. If you are forming a corporation or a partnership (non-sole owner), that fee jumps to $350.
Here is a quick breakdown of the steps:
- Submit Application: Send your completed form and the $450 fee to the CSLB in Sacramento.
- Fingerprinting: After they accept the application, they’ll send you a Live Scan form.
- Exam Notification: You’ll receive a notice to schedule your exams at a PSI testing center.
- Pay Initial Fee: After passing, pay your license fee to “activate” the number.

Post-Examination Requirements and License Maintenance
Passing the test is a huge milestone, but the CSLB won’t hand over the license until you prove you are “responsible.” This involves three main things:
- Contractor Bond: Every licensed contractor in California must have a $25,000 surety bond on file. This isn’t insurance for you; it’s a protection for the public and your employees if you fail to follow the law or finish a job.
- Workers’ Compensation: If you have even one employee (even a part-time helper), you must have workers’ comp insurance. If you are a one-man show with no employees, you can file an exemption, but be careful—the moment you hire someone, you need that policy.
- Asbestos Open-Book Exam: Every new contractor must complete a simple, open-book exam about asbestos safety. It’s mostly about making sure you know how to identify it and who to call to remove it.
You also need to complete your Live Scan fingerprinting. This is how the state checks for criminal history. Don’t worry—having a record doesn’t automatically disqualify you, but lying about it on your application definitely will!
If you are adding a classification to an existing license, you might look into 7065.2 Waiver provisions to see if some of these steps can be streamlined.
Frequently Asked Questions about the C-60 License
We get a lot of questions at Contractors License Guru. Here are the most common ones regarding the California welding contractor license.
What is the difference between AWS certification and a California welding contractor license?
This is the number one point of confusion.
- AWS Certification (e.g., D1.1): This is a “performance” certification. It proves that you, as an individual, have the physical skill to make a sound weld on structural steel. It is often required by engineers on a job site.
- C-60 License: This is a “business” license. It gives you the legal authority to sign contracts, pull permits, and run a welding company.
Think of it this way: the AWS cert proves you can weld. The C-60 proves you can run a welding business. In California, if the project is over $1,000, you need the C-60 license regardless of how many AWS certifications you have.
How much journey-level experience is required for the C-60 license?
As mentioned, you need four full years (48 months) of experience. This experience must be at the journey-level or higher (foreman, supervisor, or owner-builder).
- Military Experience: If you were a welder in the military, that time usually counts! You’ll just need to provide your DD-214 and a description of your duties.
- Owner-Builder: If you’ve done extensive welding work on your own property, you might get some credit, but the CSLB is very strict about verifying this.
What are the estimated fees for applying and renewing the C-60 license?
Beyond the initial $450 application and $200 initial license fee, you have to maintain the license.
- Active Renewal: $450 every two years (for sole owners).
- Inactive Renewal: $225 every four years if you want to keep the license but aren’t currently contracting.
- Delinquent Fees: If you forget to renew on time, the state adds a “delinquent” penalty, which can push your renewal cost up significantly (sometimes over $600-$700).
Conclusion
The demand for skilled welders in California is through the roof. With national employment for welders projected to exceed 457,000 by 2032, and senior welders in California earning upwards of $28.68 per hour (and specialized rig welders earning significantly more), there has never been a better time to step up from being an employee to being a business owner.
Obtaining your California welding contractor license is the key to unlocking those higher-tier projects and building a legacy for yourself. Yes, the paperwork is tedious and the exams are tough, but that’s what keeps the “trunk-slammers” out and keeps the professional standards high.
