UNSPSC 23271720: Trailing shield

Trailing shield is a welding enhancement tool designed for high quality gas coverage during welding of Titanium and other high alloy metals. It provides better gas coverage in the heat effected zone (HAZ) and prevents oxidation, weld defects, re-work and allows faster welding.

UNSPSC 23271720 Trailing shield is a Commodity code for welding consumables, equipment, and related supplies that state and local governments purchase to support educational welding programs, facility maintenance operations, and transit infrastructure repair. Recent solicitations under this code show schools, colleges, water districts, and transit agencies buying welding materials (rods, wire, electrodes, consumables), extraction equipment and ventilation systems for lab safety, finished welding apparatus (diesel-driven welder/generators), and turnkey track welding and maintenance services. The issuing-body mix includes community colleges (Collin College), school districts (Northside Independent School District, Mt. San Antonio Community College District), municipal water utilities (North Texas Municipal Water District), and transit authorities (Charlotte Area Transit System). Work ranges from purchasing consumables and equipment on an as-needed basis to awarding multi-year supply contracts and performing specialized field services.

Geographic activity centers on Texas (North Texas Municipal Water District, Collin College solicitations, Northside Independent School District in San Antonio, and Mt. San Antonio in California) and North Carolina (Charlotte Area Transit System).
