- Description
- NASA/GSFC plans to purchase a new 60k V electron beam welder with an 18 inch cube chamber pumped by turbo molecular vacuum pump and oil free backing pumps. This procurement is being conducted under the authority of FAR Subpart 13.5 - Test Program for Certain Commercial Items. The specifications and requirements are as follows: (1). The vacuum chamber shall be made out of fully welded stainless steel with internal dimensions of 18 in. X 18 in. X in. cube with a nominal wall thickness of 0.75 in. (2). The left side plate of chamber shall have an approximate 9 in. diameter port to which a 14 in. O.D. diameter blank flange is attached via an O ring during acceptance testing and shipping. Once delivered to NASA, the blank flange will be removed and NASA's existing 14 in. flanged, 10 in. O.D. X 16 in. long horizontal extension tube shall be attached to the left side plate opening. Exact bolt-hole pattern and vacuum sealing surface dimensions shall be provided after receipt of order. Cost to implement this feature shall be included in the quote. (3). The beam viewing must have visualization displayed on computer screen or separate HD monitor. (4). The high voltage power supply shall provide a minimum of 3 of 3kW/60kV with an adjustable beam current up to at least 50 ma. (5). The welding system shall have a PC based integrated control system for welding parameters, vacuum system functions, data storage and CNC control. (6.) A touch screen operating panel shall display various functions and status such as EB weld parameters, vacuum status, machine history and servicing data. (7). A CNC controllable, double rail, 9 in. square, fully integrated X-Y table shall be installed inside the chamber. Length of rails can be up to 18 in. long. The control system must incorporate CNC backlash compensation. (8). A function/circle generator with a beam pulser system must be incorporated to enable widening and narrowing of the electron beam depending on size of parts to be welded without rotation of the part. (9). A horizonal rotator must be mounted on the right hand side of chamber. (10). A high precision, CNC controllable, internally mounted, manual titable, rotator shall be provided. (11). The vacuum chamber shall be pumped by an oil free turbo molecular pump and a dry roughing pump. The electron gun section shall be separately pumped by its own oil free turbo molecular pump and a dry roughing pump. Size of the pumps shall be sufficient to enable pump down of the vacuum chamber to ~ 1x10 -4 mbar in 45 60 secs. The vent valve shall incorporate a micron size filter. (12). An isolation valve shall be provided between the vacuum chamber and electron gun section to keep the electron gun under vacuum during chamber venting. (13). A closed loop chiller shall be provided, if necessary, for cooling of electron beam generator, HV power supply and vacuum pumps Deliverables and Delivery Schedule. 1. Specifications described above. 2. Operating manuals 3. Maintenance and Service manuals for all equipment 4. CNC programming manual 5. Circuit diagrams 6. Wiring and cable layout 7. Safety Instructions 8. Assembly drawings 9. Electronic copy of software, drivers and computer system shall be included. 10. Recommended spare parts list 11. Delivery Schedule shall be 6 months upon receipt of order or sooner. 12. Acceptance testing shall be performed at the vendors plant prior to shipping the welder to NASA. The acceptance testing shall be witnessed by a NASA representative. Travel expenses will be borne by NASA for the testing. 13. Installation will be done by the vendor at NASA/GSFC facility followed by 2 days of on-site training. Two to three GSFC personnel who will be doing the electron beam welding shall receive the training. Cost of the installation and training shall be noted in the vendors quote. 14. Shipping charges and any custom duties and fees, etc., shall be included in the quotation. Place of Performance Manufacturing of the Electron Beam Welder will be at the vendors location. The anticipated release date of NNG13485999L is 09/23/2013. All responsible sources may submit a Quote and capability statement which shall be considered by the agency. NASA Clause 1852.215-84, Ombudsman, is applicable. The Center Ombudsman for this acquisition can be found at http://prod.nais.nasa.gov/pub/pub_library/Omb.html. T he solicitation and any documents related to this procurement will be available over the Internet. These documents will reside on a World-Wide Web (WWW) server, which may be accessed using a WWW browser application. The Internet site, or URL, for the NASA Business Opportunities page is http://procurement.nasa.gov/cgi-bin/EPS/bizops.cgi?gr=D&pin=. Prospective offerors shall notify this office of their intent to submit an offer. It is the offeror's responsibility to monitor the Internet site for the release of the solicitation and amendments (if any). Potential offerors will be responsible for downloading their own copy of the solicitation and amendments (if any). All contractual and technical questions must be submitted in writing Gilser.A.Nash@nasa.gov, not later than 9/23/2013. Telephone questions will not be accepted.
