Welding Certification & License Requirements in MassachusettsHow to Become a Certified Welder (2026)

OSHA Training Requirements

Consistent with federal OSHA requirements; Massachusetts also has its own Division of Occupational Safety but federal OSHA 29 CFR 1926.352 hot work permit requirements apply in construction.

Welding certification is primarily managed through the American Welding Society (AWS) and ASME. Most states accept AWS certifications for structural welding and ASME Section IX for pressure vessel welding. Some states have additional state-specific certification requirements, particularly for structural steel welding on public works projects.

Apprenticeship Programs

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.

Industry Certifications

No formal education is required to become a welder. However, completing a welding training program at a vocational school or community college (typically 6 months to 2 years) provides essential skills. Registered apprenticeship programs through unions offer paid on-the-job training combined with classroom instruction over 3-4 years.

Common Welding Code Standards

State-Specific Exam Requirements

Massachusetts 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.

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 Renewal

Every 9 years — AWS CWI certification is valid for 3 years, renewable twice (3+3+3=9 years total before retesting required)

State Certification Renewal

Varies by state — typically every 1-2 years with continued welding activity or retesting

Continuing Education Details

No formal continuing education required for AWS Certified Welder (CW). AWS CWI renewal requires 80 Professional Development Hours (PDHs) per 3-year cycle. Welder performance qualifications must be maintained through continued welding activity every 6 months.

Regulatory Board

AWS Certified Welder (CW) performance qualifications must be maintained every 6 months through continued welding activity or retesting. 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.
