 Welding |
 |
| ID and OD welding stations |
Welding is our core technology and includes:
- TIG
- Electron Beam
- Laser
- Spot Welding
- Orbital Welding
All welders are trained and certified per ES-1025 (MIL-STD-1595A)
by function, material type and thickness. Materials of construction
are AM350 and High nickel alloys. (Inconel, Hasteloy, Haynes)
0.001" to 0.020" thickness.
We operate thirty-eight fully functional ID welding stations
and thirty-four OD workstations. All machines are maintained
to standard specifications; this allows us to route work
to the optimum work stations as appropriate. Inside diameter
welding is achieved on tightly toleranced, semi-automated
equipment with part and operation specific tooling. Outside
diameter welding machines incorporate precise lathe bed control
and Weld Logic power units.
We maintain two electron beam welders in production: a small
volume low power capability for small diameter low penetration
sealing and welding requirements, and a large volume high
power machine for large diameter full penetration structural
welding.

| Low Power E-Beam Welding |
High Power E-Beam Welding |
Laser welding is done on our PRC STS 1800
watt Laser Welding Station manufactured and installed
in early 2000. |
|
| Metal Forming |
 Production
presses from 25 to 1200 tons of both the mechanical and hydraulic
configurations are maintained in an active production press
department. |
| Heat
Treat & Furnace Brazing |
 In house heat treatment and vacuum furnace brazing capabilities
(per MIL-H-6875 and MIL-B-7883) are maintained for use in
the manufacture of bellows and related assemblies. We operate
a total of 4 vacuum furnaces.
|
| Cleaning |
 Our cleaning room houses a 17-bath automated precision cleaning
system designed to remove organic and inorganic contamination
from metal surfaces. The system uses fully aqueous chemistry
and state-of-the-art agitation to produce ultra-clean surfaces.
Rinse water with a minimum resistivity of 2 Meg-ohms and
high efficiency dryers assure complete spot free drying.
|
| Machine Shop |
 Our machine shop includes 15 lathes, 6 milling machines,
and 7 turning centers. We manufacture and maintain all the
precision tooling required to build our products. We also
do machining for prototype activities as well as limited
production. A large production machining capacity is maintained
in a certified vendor base to service long-term production
needs.
|
| Clean Room |
 Our 1,300 square foot class 1000 clean room is equipped
for welding, leak check, function test, cleaning, inspection
and packaging. We also maintain a 300 square foot class 100
area.
|
| Leak Detection |
 Bellows welds and assembly welds are checked on our helium
mass spectrometer leak check machines. We check all components
for compliance to the specified maximum leakage levels with
a capability of 1x10-10 STD cc He/sec.
|
| Functional Test and Inspection |
 We maintain complete product testing facilities for all
aspects of product conformity. Maintaining functional test
verification according to required acceptance test criteria
consists of mechanical and dimensional verification with
electromechanical capabilities designed and maintained for
individual applications. We also maintain complete destructive
cycle, proof pressure and burst test facilities; certified
non-destructive dye penetrant testing capabilities; and an
environmental test chamber including digital programming
and readout from -73°C to +177°C.

| Life
Cycle Testing |
 Prototypes are subjected to rigorous laboratory testing
to ensure they will meet the most demanding criteria for
speed, stroke and pressure.
|
| Metallurgy
Laboratory |
 A metallurgical laboratory is maintained at this facility
and is staffed by 2 full time metallurgists as well as a
staff of technicians.
