Credential comparison
These are separate ICC special-inspection scopes. Bolting covers members, connection schedules, and high-strength bolting. Welding covers procedures, qualifications, and visual acceptance.
Study this path for member identification, faying surfaces, pretension methods, and connection-schedule coordination.
Study this path for welding procedures, personnel qualifications, fit-up, and visual acceptance. It does not replace bolting.
An employer or jurisdiction may require bolting, welding, or both. Passing one ICC module does not confer the other, and neither credential is an AWS CWI certification. Confirm the requested module name before you buy references or schedule an exam.
