New York City's skyline is built of steel. From the Empire State Building to the Freedom Tower, every beam was connected by a licensed welder. Unlike other cities where certification is enough, in NYC, you must hold a specific Class 1, 2, or 3 Welder License issued by the Department of Buildings (DOB) to work on any structural project.

💡 Key Takeaways for NYC Welders:
- Authority: NYC Department of Buildings (DOB).
- Prerequisite: Must have AWS Certification (typically D1.1 Structural Steel).
- Background: Strict criminal background check required.
- Union: Ironworkers Local 40 & 361 control the biggest jobs.
1. AWS Certification vs. DOB License
This distinction is critical:
- AWS Certification: Proves you can weld. You get this from a testing lab.
- DOB Welder License: Proves you are legally allowed to weld on permitted sites in NYC. You cannot get the DOB license without first getting the AWS cert.
2. Step-by-Step: How to Get Licensed
Step 1: Pass the AWS D1.1 Practical Test
You must go to an AWS Accredited Test Facility and pass a hands-on test.
The most common test is 3G (Vertical) and 4G (Overhead) on 1-inch thick plate using SMAW (Stick welding). This qualifies you for unlimited thickness structural welding.
Step 2: Submit Application to DOB
Once you have your AWS qualification letter, you must apply to the Department of Buildings using the LIC60 form. You will need:
- A letter from the testing laboratory.
- Social Security Card and Government ID.
- Proof of residence (Utility bill).
Step 3: Background Check
The DOB will run a background check. You must disclose any prior convictions. Honesty is key here; hiding a record will get you denied instantly.
*Get certified in SMAW (Stick) for best job prospects
💰 Welder / Ironworker Salary Potential in NYC
