Is AWS D1.1 a certification, and how do you get qualified to it?
AWS D1.1 is the American Welding Society's Structural Welding Code — Steel: a consensus standard governing the design, fabrication, inspection and welding of structural steel, adopted by reference into building codes across the United States. The American Welding Society does not issue a personal 'D1.1 certificate'. What exists is welder performance qualification to D1.1: you weld a test coupon under the code's rules, it is inspected and mechanically tested against the code's acceptance criteria, and the result is documented on a Welder Performance Qualification Record signed by the employer or contractor responsible for the work — usually with a Certified Welding Inspector verifying it. That record, not an AWS card, is what a general contractor or building official asks to see. It stays valid while you continue to weld in the process, subject to the code's continuity rules, and it belongs to the employer whose quality system produced it unless you tested through the separate AWS Certified Welder program.
- AWS D1.1 is the Structural Welding Code — Steel; AWS does not issue an individual D1.1 certificate.
- Welders qualify by test to a WPS, and the evidence is a Welder Performance Qualification Record.
- The record is issued under the responsible contractor's quality system, so it rarely transfers between employers.
- Validity is governed by continuity of work in the process, not by a calendar expiry date.
AWS D1.1 at a glance
| Cost | Testing is priced by the fabricator, testing lab or school that runs it, so it varies by provider; the D1.1 code book itself is sold by AWS at a price published on aws.org |
| Duration | One supervised test session per coupon; the code book is a reference you use for years |
| Issued by | American Welding Society publishes the code; the qualification record is issued by the employer or contractor responsible for the welding |
| Format | Hands-on welder performance qualification test — coupon welded to a WPS, then visual inspection plus bend or radiographic testing |
| Expiry | No fixed expiry; qualification remains in effect under the code's continuity rules while you keep welding in the process |
| Who needs it | Structural welders, ironworkers and fabricators on buildings, bridges and structural steel governed by D1.1 |
| Common misconception | AWS does not issue an individual 'D1.1 certification' — the code is the standard, the WPQR is the record |
| Related codes | D1.2 aluminium, D1.3 sheet steel, D1.5 bridge welding, D1.6 stainless steel |

Qualifying to D1.1, The Test and the Paperwork
The single biggest misconception
Job adverts say 'must be D1.1 certified', and welders reasonably go looking for the certificate. There isn't one from AWS. D1.1 is a code book. Welders are qualified to it, and the evidence is a Welder Performance Qualification Record (WPQR) issued under the responsible contractor's quality system, normally verified by a Certified Welding Inspector. If you want a qualification that AWS itself holds and that travels with you, that is the separate AWS Certified Welder program.
What the test actually involves
Does D1.1 qualification change structural welding pay?
Structural welding rates track the position, material and inspection regime a job demands rather than a certificate, and D1.1 qualification is normally the entry condition for the work rather than a separate line on the pay sheet. BLS reports wages by occupation, not by credential.

What AWS D1.1 Covers, Scope of the Code
The Code Itself
D1.1 covers welded structural steel of a defined minimum thickness. It is republished on a multi-year cycle, and contracts name the edition — qualifying to one edition does not automatically satisfy another.
WPS and PQR
A Welding Procedure Specification tells the welder how to weld the joint. It is either prequalified under the code's rules or qualified by testing, evidenced by a Procedure Qualification Record.
The WPQR
The Welder Performance Qualification Record lists the essential variables you tested with and the range each one qualifies you for. It is the document contractors actually audit.
The Inspector's Role
D1.1 assigns inspection duties and defines inspector qualification, which is why a Certified Welding Inspector is normally the person verifying welder qualification and production welds.
Continuity Rules
Qualification does not lapse on a date; it lapses when the welder stops using the process for the period the code allows, or when the employer has reason to question the welder's ability.
The Other D-Codes
D1.2 covers aluminium, D1.3 sheet steel, D1.5 bridges and D1.6 stainless. Structural steel work outside D1.1's scope is governed by a different code with its own qualification rules.
How do you get qualified to AWS D1.1, step by step?
Establish which code and edition applies
Contracts and building officials name the code and the edition. D1.1 governs structural steel; bridge work usually falls under D1.5 and sheet steel under D1.3. Qualifying to the wrong document is a wasted test.
Get the WPS you will weld to
Welder qualification is always against a written procedure. The responsible contractor supplies a prequalified WPS or one qualified by testing. You cannot qualify in a vacuum.
Weld the coupon under supervision
Test at a fabricator, an accredited testing lab or a technical college that runs D1.1 testing. Fees are set by the facility, so they vary by provider. The coupon must reflect the position and thickness range your production work needs.
Pass visual inspection, then mechanical testing
The coupon is inspected against the code's visual acceptance criteria first, then guided-bend or radiographic tested where the code permits. A Certified Welding Inspector normally performs or verifies the evaluation.
Take custody of the WPQR and maintain continuity
The signed Welder Performance Qualification Record is the evidence. Keep a copy: it lists your qualified ranges. Qualification remains in effect under the code's continuity rules while you keep welding in the process for that employer.
Why D1.1 Is Effectively Mandatory
D1.1 is a voluntary consensus standard until a jurisdiction adopts it — and jurisdictions adopt it. The International Building Code and the AISC specifications reference AWS D1.1 for structural steel welding, so on most commercial construction in the United States the code applies as a matter of law through the building code rather than as a contract preference. That is why a building official or special inspector can stop structural welding and ask for the WPS and the welder qualification records: the paperwork is part of code compliance, not shop bureaucracy.
