Notes
Massachusetts does not require a statewide occupational license for general welders. However, welders working on gas piping and pressure systems may need to comply with regulations enforced by the Massachusetts Department of Public Safety. The Office of Public Safety and Inspections administers boiler and pressure vessel rules. Verify with state agencies for specialized welding work.
