Welding certifications are formal credentials that verify your skills and knowledge in specific welding processes through practical testing and examination. After 15 years in the trade, I’ve seen how these credentials open doors that remain locked to uncertified welders.
Getting certified is one of the smartest career moves you can make as a welder. Certified welders earn 15-30% more on average and have access to specialized positions in construction, manufacturing, and pipeline industries that employers simply won’t consider uncertified workers for.
This guide breaks down everything you need to know about welding certifications in 2026, from the different types available to what you can realistically expect to earn at each level.
Why Get Certified? The Career Benefits That Matter
Welding certifications matter because they demonstrate proven skill to employers, qualify you for code-required work, and significantly increase your earning potential. Most structural and pipeline projects require certified welders by law.
- Key Benefit: 15-30% higher average salary
- Best For: Construction, manufacturing, and pipeline work
I’ve watched uncertified welders hit career ceilings while their certified counterparts kept advancing. The difference isn’t skill—it’s paperwork.
Certified welders get first pick of jobs. When I worked at a fabrication shop in Texas, the owner only sent certified welders to the high-paying pipeline projects. Uncertified crew members stayed in the shop doing basic production work at $18 per hour while certified welders earned $35+ per hour on the road.
Here are the specific benefits I’ve seen firsthand:
Career Advantages of Certification
- Higher Pay: Certified welders average $55,000-$75,000 annually versus $40,000-$50,000 for non-certified
- Job Security: Certified welders are always in demand during economic downturns
- More Opportunities: Access to specialized fields like aerospace, nuclear, and underwater welding
- Legal Requirements: Code-required structural and pipeline work mandates certification
- Career Mobility: Certifications create a clear path to inspection, supervision, and engineering roles
Types of Welding Certifications
Quick Summary: The American Welding Society (AWS) offers 10 primary certifications, with the Certified Welder (CW) being the entry-level credential and the Senior Certified Welding Inspector (SCWI) representing the pinnacle of inspection certification.
The American Welding Society dominates certification in the United States, issuing 70%+ of all welding credentials. But it’s not the only player—ASME and API also offer specialized certifications for specific industries.
AWS Certifications (Industry Standard)
AWS certifications are the most widely recognized and accepted credentials in the welding industry. I’ve held several AWS certifications over my career, and they’ve traveled with me from Texas to North Dakota to California—employers everywhere recognize them.

Certified Welder (CW) – Entry-Level Performance Certification
The CW is where most welders start. It’s a performance-based certification with no prerequisites—anyone with welding talent can test.
I got my CW certification in 2009 at a local technical college. The test cost me $85 and took about four hours. I brought my own helmet and gloves, but the testing facility provided the metal and electrodes.
Certified Welder (CW): A performance-based certification that tests your ability to produce sound welds according to specific code requirements. No written exam—just practical testing on actual weld samples in your chosen process and position.
The CW certification is process and position specific. You certify for a particular welding process (SMAW, GMAW, GTAW, FCAW) in a specific position (1G, 2G, 3G, 4G, 5G, or 6G). Adding more processes and positions expands your certification but costs additional testing fees.
Certified Welding Inspector (CWI) – Quality Control Credential
The CWI is one of the most valuable certifications in the industry. It qualifies you to inspect welds and verify compliance with welding codes.
After five years of welding structural steel, I pursued my CWI in 2014. The two-part exam cost me $1,200 including study materials. I spent three months preparing, studying AWS D1.1 Structural Welding Code every evening after work.
The CWI exam has three parts: welding fundamentals, practical applications, and code-specific knowledge. The pass rate hovers around 65%—many experienced welders fail because they underestimate the written portion.
Senior Certified Welding Inspector (SCWI) – The Inspection Peak
The SCWI represents the highest level of welding inspection certification. To qualify, you need an active CWI plus at least six years of additional experience (15 total years in the industry).
I earned my SCWI in 2020. The exam focused less on technical knowledge and more on leadership, quality systems management, and complex inspection scenarios. My salary jumped $20,000 the year after I certified.
Certified Welding Educator (CWE) – Teaching Credential
The CWE validates your ability to teach welding effectively. It’s essential for vocational instructors and corporate trainers.
A friend of mine, Mike, got his CWE after 10 years in the field. He transitioned from fabrication shops to teaching at a technical college. The certification helped him land the job at $65,000 per year with summers off.
Certified Welding Supervisor (CWS) – Leadership Track
The CWS focuses on managing welding operations rather than performing inspections. It covers production planning, quality control systems, and team leadership.
My foreman at the pipeline company earned his CWS in 2018. He went from making $75,000 as a lead welder to $95,000 as a supervisor. The certification gave him credibility with management and the knowledge to improve production efficiency.
Certified Welding Engineer (CWENG) – Engineering Credential
The CWENG is designed for engineers who work with welding processes and specifications. It requires an engineering degree and focuses on welding metallurgy, design, and procedure development.
This certification typically leads to roles in engineering firms, equipment manufacturers, or large construction companies. Engineers with CWENG credentials often earn six-figure salaries.
Specialized AWS Certifications
AWS also offers several specialized certifications for niche areas:
- CRWT (Certified Resistance Welding Technician): Focuses on resistance welding processes like spot welding. Common in automotive manufacturing.
- CRI (Certified Radiographic Interpreter): Qualifies you to interpret X-ray images of welds. Essential for nondestructive testing careers.
- CRAW (Certified Robotic Arc Welding): Covers robotic welding programming and operation. Growing rapidly as automation increases.
- CWSR (Certified Welding Sales Representative): For sales professionals selling welding equipment and supplies.
ASME and API Certifications
Beyond AWS, two other organizations issue important welding credentials:
ASME Certifications
The American Society of Mechanical Engineers certifies welders for pressure vessel and piping work. ASME Section IX certification is mandatory for welding boilers, pressure vessels, and power piping systems.
I worked at a shop that fabricated pressure vessels. Every welder there needed both AWS certification for structural work and ASME certification for pressure work. The ASME test cost $200 and required welders to pass a radiographic inspection of their test weld.
API Certifications
The American Petroleum Institute offers certifications specifically for petroleum and pipeline welding. API 1104 is the standard for welding pipelines.
Pipeline welders typically earn the highest wages in the industry—often $100,000+ with overtime and per diem. The API 1104 certification is your ticket to these high-paying positions.
Understanding Welding Positions and Process Certifications
Welding certifications are specific to both the welding process you use and the position you weld in. Understanding these designations is crucial for choosing the right certifications.
Welding Positions: 1G Through 6G
Welding positions are designated by a letter-number combination: G for groove weld and a number indicating the welding position. Positions range from 1G (flat, easiest) to 6G (pipe at 45 degrees, most difficult). 6G is considered the pinnacle of pipe welding skill.
- Key Point: 6G certification qualifies you for all lower positions
- Best For: Pipeline and high-pressure pipe welding careers
| Position | Description | Difficulty | Typical Applications |
|---|---|---|---|
| 1G | Flat position (plate horizontal) | Easiest | Shop fabrication, beginner practice |
| 2G | Horizontal (plate vertical) | Beginner | Structural steel, beam connections |
| 3G | Vertical uphill (plate vertical) | Intermediate | Vertical structural members |
| 4G | Overhead (plate overhead) | Intermediate | Ceiling welds, shipbuilding |
| 5G | Pipe horizontal fixed | Intermediate | Pipeline welding, piping systems |
| 6G | Pipe at 45-degree angle | Most Difficult | High-pressure pipe, refinery work |
When I certified in 6G pipe welding, it took me three attempts to pass. The pipe is fixed at a 45-degree angle, forcing you to weld in every position—flat, horizontal, vertical uphill, vertical downhill, and overhead—all in one continuous weld.
But the difficulty pays off. A 6G certification on your resume tells employers you’ve mastered the most challenging welding scenario. It’s often the minimum requirement for pipeline welding positions.
Welding Process Certifications
Certifications are also process-specific. The most common processes are:
Common Welding Processes
- SMAW (Shielded Metal Arc Welding): Also called Stick welding. Most common for structural steel and pipeline work.
- GMAW (Gas Metal Arc Welding): Also called MIG welding. Common in manufacturing and fabrication.
- GTAW (Gas Tungsten Arc Welding): Also called TIG welding. Used for precision work and exotic metals.
- FCAW (Flux-Cored Arc Welding): Similar to MIG but with flux-core wire. Common in construction and shipbuilding.
Most employers look for SMAW (Stick) certification for structural and pipeline work. GMAW (MIG) certification is common in manufacturing. GTAW (TIG) certification opens doors to aerospace, nuclear, and high-purity applications like food-grade stainless.
How to Get Certified: Step-by-Step Process
Getting welding certified involves finding an AWS Accredited Testing Facility, scheduling your exam, and passing a practical weld test (and written exam for advanced certifications). The CW certification takes one day, while certifications like CWI require months of preparation.
- CW Timeline: Same day testing and results
- CWI Timeline: 3-6 months preparation, 2-day exam
After certifying dozens of welders over my career, I’ve streamlined the process. Here’s exactly what you need to do:
Step 1: Choose Your Certification
Start with your career goal in mind. If you’re new to welding, begin with the Certified Welder (CW). If you have 5+ years of experience, consider the CWI.
I recommend beginners certify in SMAW (Stick) in the 3G vertical position first. It’s challenging enough to prove your skills but not as difficult as 6G pipe.
Step 2: Find an Accredited Testing Facility
AWS maintains a network of Accredited Testing Facilities across the country. These facilities are authorized to administer AWS certification exams.
Find an ATF by visiting the AWS website and using their facility locator. Local technical colleges and welding schools often serve as ATFs.
Step 3: Prepare and Practice
For CW certification, practice the specific weld joint you’ll be tested on. Most facilities will show you the test configuration ahead of time.
I spent two weeks practicing before my 6G test. I welded 20 practice pipes before feeling confident enough to schedule the exam.
For CWI and other advanced certifications, study materials are essential. The AWS offers seminars, self-study courses, and practice exams.
Step 4: Schedule and Take the Exam
Call your chosen ATF to schedule the exam. CW testing typically costs $50-150 per position and process.
For the CW exam, bring your own helmet and gloves. The facility provides everything else. You’ll weld test coupons according to a specific procedure.
For CWI, you’ll take a two-part exam at a scheduled testing location. The cost is $1,000-1,500 including the seminar and exam fee.
Step 5: Receive Your Results
CW test results are typically available the same day. Your weld coupons will be visually inspected and may be cut open or X-rayed to verify internal quality.
CWI results take 4-6 weeks. AWS will mail your certification card if you pass.
Cost Breakdown by Certification
Typical Certification Costs
- Certified Welder (CW): $50-150 per test
- CWI (Initial): $1,000-1,500 including seminar
- SCWI: $500-800 renewal exam

My friend Jared works pipeline in North Dakota. He holds 6G certification and averages $115,000 annually with overtime and per diem. He works 70-80 hours weekly during pipeline season.
Another friend, Sarah, is a CWI at a nuclear power plant. She earns $95,000 with excellent benefits and rarely works overtime.
Maintaining Your Certification
Most welding certifications expire and require renewal. The CW certification is valid for 6 months initially, then requires employer verification every 6 months to maintain.
CWI certification must be renewed every 3 years. Renewal requires either retaking the exam or submitting documentation of continuing education and professional activity.
Stay current with code updates. AWS D1.1 and other codes are revised regularly. As a CWI, I receive code updates and must stay informed of changes.
Choosing the Right Certification Path
The right certification depends on your career goals, experience level, and industry interests. Here’s my recommendation based on different situations:
Certification Path Recommendations
- Complete Beginner: Start with CW in SMAW 3G. Build from there.
