I remember how confusing the certification landscape felt when I first started learning about it. There are so many acronyms and standards that it can seem impossible to figure out which one you actually need. I want to simplify this for you because choosing the right first certification can set the trajectory for your entire welding career.
The most common starting point for welders in the United States is certification under AWS D1.1, which is the American Welding Society’s Structural Welding Code for Steel. This is the standard that governs welding on buildings, bridges and other structural steel applications. If you are looking for a versatile first certification that opens the most doors, this is the one I recommend. Most fabrication shops, construction companies and general welding employers recognize and value D1.1 certification.
Your D1.1 certification test will require you to weld a specific joint configuration in a specific position using a specific process. The most common entry-level test is a 3G (vertical up) and 4G (overhead) plate test using SMAW, which is stick welding. Passing this qualifies you for flat, horizontal, vertical and overhead positions, which covers most structural work you would encounter on a job site.
If you are interested in pipe welding, you will want to look at certifications under ASME Section IX. ASME governs welding on pressure vessels, boilers and piping systems. Pipe welding certifications are more specialized and generally command higher pay. A common starting pipe test is a 6G certification, which requires you to weld a pipe joint in a fixed position at a 45-degree angle. Passing 6G qualifies you for all pipe positions and is highly valued in industries like oil and gas, power generation and petrochemical.
There are also certifications specific to certain industries. API 1104 covers pipeline welding for the oil and gas sector. AWS D1.2 covers structural aluminum. AWS D1.6 covers stainless steel. These are worth pursuing once you have your foundational certification and want to specialize.
One thing I want to be clear about is that welding certifications are not permanent in the way many people assume. Most certifications need to be maintained through continued employment in the relevant process and position. If you stop welding for an extended period, your certification may lapse and you will need to retest. Keep this in mind as you plan your career moves.
When it comes to where to get tested, many community colleges and trade schools have AWS-accredited testing facilities. Some employers will also sponsor your testing, especially if you are coming in through a staffing agency for welders that partners with companies willing to invest in developing their workforce.
My advice is to start with the certification that matches the type of work most available in your area. Look at job postings, talk to local shops and figure out what employers are asking for. Then go get that certification and start building from there.
