How to Get Started
Most trades have a clear entry path. Here's the fastest route to becoming a certified welding professional:
- Start with an apprenticeship or entry-level position to gain documented work experience — required for most certifications.
- Pursue entry-level certifications first (like EPA 608 for HVAC or OSHA 10 for safety) — these are inexpensive, quick, and immediately valuable.
- Accumulate the required work experience hours for your target certification. Keep records of projects, employers, and hours.
- Apply for the certification exam. Most exams have study materials available — dedicate 40–80 hours of study time for mid-level certifications.
- Pass your exam and add the credential to your resume, LinkedIn, and business materials. Recertify on schedule to maintain active status.
State Licensing vs. National Certification
Important: Most states require welding contractors to have a state license IN ADDITION to national certifications. National certifications demonstrate skill and knowledge; state licenses give you legal authorization to work and pull permits.
Check your state's requirements in our state licensing guides. Many states recognize national certifications as partial exam waivers or experience documentation.
