About United States Welding, Inc.
United States Welding, Inc., doing business as Rocky Mountain Air Solutions, is a woman-owned small business headquartered in Denver, Colorado, that supplies industrial gases, cryogenic services, and compressed gas cylinders to federal agencies as a prime contractor (100% of recent awards), operating primarily under small business set-asides across civilian and defense agencies. The vendor has maintained federal contractor status since 2002 and competes predominantly on total small business set-asides, with recent work spanning liquid nitrogen, liquid oxygen, compressed air cylinders, and tank repair services.
Rocky Mountain Air Solutions' customer base is concentrated in research and testing operations. The top five funding agencies account for 71% of combined potential value, led by the Department of the Army Test and Evaluation Command (4 awards, $775 thousand combined potential value) for bulk liquid nitrogen supply to Dugway Proving Ground, Utah; the Department of Agriculture Agricultural Research Service (4 awards, $634 thousand) for high-purity liquid nitrogen delivery to Fort Collins, Colorado research facilities; and the Department of Commerce National Oceanic and Atmospheric Administration (8 awards, $412 thousand). The Department of the Interior Fish and Wildlife Service Region 6 and Bureau of Reclamation together represent $346 thousand across five awards focused on oxygen and nitrogen supply and tank repair at national fish hatcheries and hydroelectric facilities. The vendor's NAICS profile splits across pharmaceutical preparation manufacturing (52 awards), industrial gas manufacturing (21 awards), and chemical merchant wholesalers (9 awards), with primary PSC codes aligned to compressed and liquefied gases (25 awards) and medical and surgical equipment (38 awards).
The vendor holds a single-award Blanket Purchase Agreement with the Department of the Air Force Global Strike Command (awarded February 1, 2026, ceiling $35 thousand, ultimate completion January 31, 2031) for lease and recertification of compressed gas cylinders — including 146 breathing air cylinders and nitrogen and oxygen cylinders — at F.E. Warren Air Force Base in Wyoming to support 15 Missile Alert Facilities and the 90th Missile Wing. The largest active contract is a five-year total small business set-aside from the Army Test and Evaluation Command (awarded April 16, 2024, ceiling $435 thousand, ultimate completion April 16, 2029) covering 9,000 gallons per month of 99.999% pure liquid nitrogen with 24 scheduled annual deliveries to Dugway. A $365 thousand total small business set-award from USDA Agricultural Research Service (awarded March 5, 2024, ultimate completion March 4, 2029) supplies approximately 100,000 cubic feet annually of Type II Class B 99.9998% pure liquid nitrogen to Fort Collins.
Activity has remained relatively flat — one award in 2022, two in 2023, four in 2024, declining to two each in 2025 and 2026 — with combined potential value of $3.1 million across 100 prime awards and $1.7 million obligated to date (56% obligated). The recompete cliff shows three awards with ultimate completion dates in the next twenty-four months, carrying $353 thousand combined potential value and exposing the vendor to recompete on smaller transactional awards. The vendor operates as parent only with no named sub-awards in the source data.
