Notes
Pennsylvania does not require a statewide occupational license for general welders. The Pennsylvania Department of Labor and Industry regulates boilers and pressure vessels but does not issue a general welder license. Some municipalities (e.g., Philadelphia) may have local welding licensing requirements. Employer certifications per AWS or ASME are commonly required.
