The Connecticut Welder Guide

Connecticut DCP has limited welding credentials inside the heating, cooling and sheet metal work license area. The official source describes a G-8 limited welding journeyperson credential for pipe and associated fittings. Do not treat this as a blanket license for every welding job.

1. Connecticut DCP places welding, valves and machinist licensing under the heating, cooling and sheet metal work license area. (Source: https://portal.ct.gov/dcp/license-services-division/all-license-applications/welding-valves-and-machinist-trades-licensing; verbatim: “Welding, Valves and Machinist Application and Information (covered under Heating, Cooling and Sheet Metal Work, Hearth Product Work, Fuel Gas Work)”)

2. The G-8 limited welding journeyperson credential is limited to welding pipe and associated fittings and materials. (Source: https://portal.ct.gov/dcp/occupational-and-professional-division/occupational--profess/welding-valves-and-machinist-licenses-and-scope-of-work; verbatim: “The holder of this license may perform only work limited to the welding process of all pipe and associated fittings and materials”)

3. Connecticut DCP says the G-8 limited welding exam qualification requires registered apprenticeship or equivalent experience and training plus current pipe welding certification. (Source: https://portal.ct.gov/dcp/occupational-and-professional-division/occupational--profess/welding-valves-and-machinist-licenses-and-scope-of-work; verbatim: “The requirements to qualify for this license examination shall be the completion of a registered apprenticeship program or equivalent experience and training”)

Registered apprenticeship oversight in Connecticut runs through Connecticut Department of Labor Office of Apprenticeship Training (no URL on file).
