Atlas Quality Assurance

Serial Numbered Traceable Control Throughout
The entire manufacturing process from materials purchasing to finished goods is serial numbered traceable controlled. In addition Atlas destructively testes each bi-metallic part three times and ultimately helium leak certifies all qualifying parts and assemblies. This process assures you that Atlas components and assemblies will meet your needs without failure.

Plate Handling Process
Prior to bonding each plate is given a Plate Serial Number that is referenced to Materials Certifications for all materials used in that particular bonded plate. After bonding each serial numbered plate is ultrasonically mapped (according to ASTM A578/a578M-96) identifying all non-bond areas. The map and plate number is recorded.

Part Discs Control
The mapped plate is then plotted into discs for each flange size. The plate is then abrasive water jet cut with each disc remaining in its’ cut out hole location on the plate. The each disc is given a Disc Serial Number as it remains in the plate.

Cryogenic Shock Destructive Test
Each Disc is emerged in LN2 and the immersed in hot water. Any failures are recorded by serial number.

Disc Rough Machining & Cryogenic Shock
The Outside Diameter (OD) and the Inside Diameter (ID) of each serial numbered part is rough machined and again cryo-shocked. The bond interface is then tested using dye penetrant testing (AMS 2644, ASTM E165, ASTM E 1417, NAVSEA 250-1500-1, ASME). Failures are recorded and destroyed.

Finished Flange and Components & Cryogenic Shock
The serial numbered part is finished machined and tested to meet its dimensional specification. The part is then cryo-shocked a third time and dye penitrant tested and dimensionally tested, failures recorded and discarded.

Disc Pre-Cleaning
Serial numbered parts are washed in a citric detergent removing machining coolants and debris.

Helium Leak Test Qualification
Each serial numbered part is individually helium tested using a Pfieffer Vacuum Qualy Dry helium leak detector to meet Atlas Standard >1 x 10-9 cc he /sec. failures recorded and discarded.

Disc & Component Marking
Each part that passes these stringent standards is electro-chemically etched with its’ serial number traceable throughout this manufacturing process to the original materials purchased. The finished part number is recorded and a master list of Atlas Vacuum Qualified Components and assemblies.

Final Cleaning and Packaging
Each qualified part is cleaned according to Atlas 005-006 AL/SS cryo-component UHV cleaning procedure. Each part is bagged in an electro-static shield bag and is heat sealed and marked with its part.
