High-Purity Metal Fabrication & Welding Services

The contract calls for specialized TIG orbital welding of 316L stainless steel tubing to produce leak-tight, contamination-free joints capable of meeting the stringent demands of ultra-high vacuum environments. The work requires precision welding techniques to ensure structural integrity and purity, with no tolerance for defects or particulate introduction. Non-destructive testing must be conducted to validate weld quality, and a detailed weld log must be maintained to document every weld performed, including parameters, inspection results, and operator identification, ensuring full traceability and compliance with high-purity standards. This subcontract is issued under the NAICS code 332322 for Metal Fabrication and is associated with SLAC National Accelerator Laboratory, a Department of Energy contractor, with performance required at Menlo Park, California, 94025. The solicitation was posted on June 25, 2026, with a response deadline of June 26, 2026, indicating an extremely tight turnaround for proposals. The nature of the work implies strict adherence to cleanliness protocols and industry-specific requirements for particle control, making this opportunity targeted toward suppliers with proven experience in high-purity metal fabrication for scientific or industrial vacuum applications.
