UNSPSC 73181902: Metal inert gas MIG welding services

UNSPSC 73181902 Metal inert gas MIG welding services is a Commodity code encompassing field and shop welding, fabrication, and repair work on infrastructure, equipment, and structural steel across water utilities, transit systems, school districts, and municipal departments. State and local governments procure MIG welding primarily for maintenance and capital repairs—water vault fabrication, pipeline and tank repairs, bridge railing installation, rail track welding, and facility-infrastructure restoration—often bundled with related metalworking, plasma cutting, or stainless steel welding services. The issuing-body mix spans water districts and municipal utilities (Alameda County Water District, North Texas Municipal Water District, City of Tampa Water Department, New Smyrna Beach Utilities), transit authorities (Charlotte Area Transit System), school districts (Austin Independent School District, Mt. San Antonio Community College District, Northside Independent School District), and county or city departments of public works and facilities (Greenville County, Hillsborough County, City of Atlanta, City of Statesboro). Counties and municipalities issue most opportunities; water utilities appear frequently as repeat buyers.

Recent activity concentrates in California, Texas, North Carolina, Georgia, and Florida. Representative opportunities include Greenville County's RFP for Laurel Creek Pedestrian Bridge railings fabrication and installation (RFP27001, due August 5, 2026) requiring AWS D1.1-certified welders and weathering steel per ASTM specifications; Charlotte Area Transit System's Blue Line track welding services rebid (RFP 269-2026-1950-2, due March 6, 2026) for FRA-compliant rail end, engine burn, switch point, and thermite field welding with 24/7 emergency response; City of Tampa Water Department's as-needed welding and fabrication for water infrastructure on an ITB with 5% SLBE discount (ITB 26-P-00401, due July 31, 2026, estimated $70,000); Alameda County Water District's on-call field and shop welding services (IFB 252619, due May 2, 2026) for approximately 1,500 field and 500 shop hours annually requiring 6G pipe certification; and Hillsborough County's mobile welding services (ITB 26-00291, due June 29, 2026, estimated $207,429.10 through July 2028) requiring TIG, MIG, and arc certifications with four-hour response on weekdays. Prevailing wage applies in California; bonding, insurance, and safety certifications (confined-space entry, OSHA compliance, AWS credentials) are standard across all jurisdictions. Most contracts offer one-year or two-year initial terms with renewal options.
