Notes
Illinois does not require a statewide occupational license for welders. The Illinois Department of Financial and Professional Regulation does not issue a welder-specific license. Some municipalities such as Chicago may have local requirements. Pressure vessel and boiler welders must comply with the Illinois Boiler and Pressure Vessel Safety Act enforced by the Illinois Department of Labor (https://labor.illinois.gov/).
