Steps
Go to nyc.gov/site/buildings/industry/obtain-a-nyc-welder-license.page for the current official requirements
Confirm the applicant needs certification from either the American Welding Society or the New York State DOT, plus proof of fitness to make structural welds and passage of operator qualification tests
Check the visual acuity test requirement, which must be documented on a DOB-prescribed form and is tied to the license term
Confirm that all new applications, renewals, and reissuances must be filed through DOB NOW: Licensing (effective since November 2018), not paper forms
Separately verify whether the specific job site also requires an FDNY Certificate of Fitness (e.g., Type G-60 for torch use of flammable gases), since that is issued by FDNY, not DOB, and is a distinct credential
Check nyc.gov/site/buildings/industry/welder-renew-license.page for renewal-specific steps if the license is not new
Known gotchas
The DOB welder license and the FDNY Certificate of Fitness are two different credentials from two different agencies — having one does not satisfy the other's requirement
Requirements and the DOB NOW filing system change; always check the live nyc.gov pages rather than relying on older PDFs or third-party summaries, since the underlying Administrative Code (Title 28, Article 407) is periodically amended
