Welding training programs are available through community colleges, vocational/technical schools, and union apprenticeships. Programs typically last 6 months to 2 years and cover various welding processes (SMAW, GMAW, FCAW, GTAW). Programs typically cover SMAW, GMAW, FCAW, and GTAW processes.
Registered apprenticeship programs are available through unions (United Association, International Brotherhood of Boilermakers, Ironworkers) and the U.S. Department of Labor. Apprenticeships typically last 3-4 years and combine on-the-job training with classroom instruction.
The American Welding Society (AWS) certifications are accepted in California. Key certifications: AWS Certified Welder (CW), AWS Certified Welding Inspector (CWI), AWS Certified Welding Educator (CWE). Pass welding performance qualification tests. Common standards: AWS D1.1 — Structural Welding Steel, AWS D1.2 — Structural Welding Aluminum, AWS D1.5 — Bridge Welding Code, +2 more.
California requires a state welding license. California requires welding certification for structural steel work per Cal/OSHA. Welders must be certified to AWS D1.1 or applicable standard for structural work. State certification fee: $100-$300.
ASME Section IX required for welding on boilers and pressure vessels; Cal/OSHA Pressure Vessel Unit oversees this in California. AWS D1.1 certification required for structural steel welding per Cal/OSHA Title 8
California operates a State OSHA Plan. Welders must comply with state-specific occupational safety regulations, including OSHA 10/30-hour training as required by employers.
AWS renewal: CWI certification is valid for 3 years, renewable for two consecutive 3-year periods (3+3+3 = 9 years), after which recertification is required. 3rd and 6th year renewal by work experience: $650 (member) / $915 (non-member). 9-year recertification options include Part B exam or 80 PDHs.

AWS CWI Exam
The AWS Certified Welding Inspector (CWI) exam consists of three parts: Fundamentals, Practical, and Code Book. Requires 5+ years welding experience or combination of education and experience. Exam fee: $1,100 (non-members) / $830 (AWS members).
Common Welding Code Standards
State-Specific Exam Requirements
California requires welders to pass a performance qualification test per applicable code (AWS D1.1, ASME Section IX, or state-specific standard).
Welders must pass a performance qualification test (also known as a “weld test”) to demonstrate their ability to produce sound welds per the applicable code. Tests are administered at AWS Accredited Test Facilities and cost $35-$50 per position. The AWS Certified Welding Inspector (CWI) exam is a separate, more advanced certification for those overseeing welding work.
Insurance Coverage for Welding Contractors
Mostly verifiedGeneral Liability
General liability insurance of $500,000 to $1,000,000 is typically required for welding contractors. Coverage protects against property damage and bodily injury claims.
Workers' Compensation
Workers' compensation insurance is required in most states for welding businesses with employees. Premiums for welding are higher than average due to the hazardous nature of the work.
Professional Liability
Professional liability (errors & omissions) insurance is recommended for welding inspectors and engineers. Not typically required for production welders.
Welding contractors typically need general liability insurance of $500,000 to $1,000,000. Workers' compensation insurance is required in most states for businesses with employees. Due to the hazardous nature of welding, insurance premiums tend to be higher than average construction trades.

AWS CWI certification is valid for 3 years and requires 80 Professional Development Hours per cycle for renewal. State certifications, where required, typically have separate renewal timelines.
California's Cal/OSHA requires welding certification for structural work. The state has some of the highest welder salaries due to cost of living and strong union presence.
Welding certification (not state licensure) is the primary credential for welders in most states. AWS (American Welding Society) certifications are the industry standard.
AWS Certified Welder (CW) performance tests must be maintained every 6 months through continued welding activity or retesting.
ASME Section IX certification is required nationwide for welding on boilers and pressure vessels regardless of state licensing requirements.
California requires a state-specific welding certification or license for certain types of welding work. See details above.
OSHA hot work permits (29 CFR 1926.352) are required for welding in construction environments nationwide.
