We have decades of experience producing HV/UHV/XHV rated weldments and integrated assemblies. Our Quality Assurance (QA) team utilizes ISO-certified cleaning and inspection programs to guarantee our products are ready for installation upon delivery. All welded assemblies are thoroughly helium leak tested, and certified welding inspectors examine all critical weld joints. Additionally, our QA team can provide a myriad of value-added services prior to shipment including: assembly, bake out, RGA scan, dry nitrogen backfill, and coordinate measuring (CMM) inspection reports.
Anderson Dahlen recently completed a custom vacuum chamber for a national laboratory. The total assembly, consisting of one top and one bottom chamber, was constructed of 304/304L stainless steel with an electropolish finish. Based on the design, fabrication, and cleaning procedures, the chamber can achieve ultra-high vacuum (UHV) levels. A Factory Acceptance Test (FAT) was also conducted, passing a leak rate at 9.62×10-12 std cc/sec (helium) leak rate with a base pressure of 2.74×10-7 Torr.
