About Weldall Mfg., Inc.
Weldall Mfg., Inc., a Waukesha, Wisconsin-based for-profit Subchapter S manufacturer, supplies structural welded metal fabrications to NASA and Army programs primarily as a subcontractor, with 79% of recent awards as prime contracts and 21% as subcontract work. The company operates in NAICS 332312 (Fabricated Structural Metal Manufacturing) and related metal fabrication categories, competing full-and-open with no SBA set-aside designations in recent activity.
Weldall's federal footprint concentrates almost entirely on NASA human spaceflight. Of 14 total awards spanning 2014 to early 2026, NASA Marshall Space Flight Center accounts for 8 awards worth $17.4 million combined potential value — the entire decision-relevant customer base. Three recent subcontract awards (dated December 2025, January 2026, and February 2026) support the Space Launch System Universal Stage Adapter, the structural interface connecting the Exploration Upper Stage to the Orion spacecraft. All three awards cover procured goods and services from June 2017 through September 2028 in support of the same contract scope: design, development, test, evaluation, production, and delivery of USA structures for Exploration Mission 2 through Exploration Mission 8, including post-delivery vehicle integration and support. NASA Glenn Research Center holds three additional awards (dollar values not specified in source), and the Department of the Army TACOM Life Cycle Management Command holds three awards totaling $78 thousand. Combined potential value across all awards stands at $17.4 million, with combined dollars obligated at $17.8 million (102% of potential value), indicating full or over-obligation.
Activity is episodic rather than sustained. The past five years show one award in 2015, two in 2017, one in 2018, then a gap until two awards in 2026. The three most recent subcontract awards, all within five months of the reference date (December 2025 to February 2026), suggest active engagement on the SLS USA production stream. The source does not identify the prime contractor on the USA subcontract work or name other subcontractors, limiting visibility into Weldall's tier-one relationships on this platform.
