UNSPSC 23271402: Ultrasonic welding machine

Ultrasonic welding machinery joins the contacting surfaces of two pieces by subjecting them to a static normal force and oscillating shearing (tangential) stresses. It can be used with a wide variety of metallic and nonmetallic materials, including dissimilar metals and is extensively used for joining plastics.

UNSPSC 23271402 Ultrasonic welding machine, a Commodity code, covers welding equipment and related supplies procured by state and local governments, though recent opportunities show a mix of specific welding machinery, consumables, and laboratory setups rather than ultrasonic welders specifically. State and local buyers under this code include school districts establishing welding laboratory programs, municipal utilities, and community colleges. Dalton Public Schools' July 2026 IFB for welding lab equipment at The Dalton Academy included nine Powermig 262MP Edu OnePak units alongside plasma cutters and saws, with delivery required within three days and a one-million-dollar general liability insurance requirement. Collin College and Collin County Community College District both issued multi-vendor, three-year ITBs for welding materials, supplies, and equipment covering consumables such as welding rods, tungsten electrodes, flat bars, sheets, tubes, and pipes in various compositions, with estimated annual volumes around $400,000 and evaluation criteria spanning price (35 percent), references (15 percent), quality (15 percent), and state-of-Texas vendor status (5 percent).

Recent activity clusters in Texas and Georgia. The North Texas Municipal Water District's July 2026 RFB for two Lincoln Frontier 400X diesel-driven welder/generators and Dalton Public Schools' September 2026 IFB (due September 25) represent equipment-specific procurements, while Collin College's FY2024-ITB-020 (bid deadline March 19, 2024) and Collin County Community College District's FY2024-ITB-024 (bid deadline April 19, 2024) represent broader consumables contracts encouraging small, minority, veteran, and female-owned business participation. Community colleges appear to be repeat buyers of welding materials under multi-vendor frameworks with stable three-year terms, while school districts and utilities tend to procure specific equipment via single-award IFBs or RFBs with compressed timelines.
