Precision metal joining is our core technology especially in the area of thin metal stock (.001” to .020” thick). Our welding technologies include:
- Tungsten Inert Gas (TIG)
- Electron Beam
- Laser,
- Spot welding
- Orbital welding
These techniques are employed to join a variety of metals including stainless steel, Inconel, Hastelloy, titanium and other exotic materials. All welders are trained and certified by function, material type and thickness.
Weld equipment includes multiple ID and OD welding stations for bellows manufacturing. Machines are set up in flexible work cells and employees cross trained to optimize manufacturing capability and minimize delivery time. Our laser welder and E-beam welders are utilized where higher power control and small spot size is critical to the finished product.
All bellows sheet metal components are produced in house. The press department houses production presses from 25 to 1200 tons again allowing for highly flexible manufacturing and planning. Welding is supported in house by heat treating and brazing facilities as well as a brand new clean line. All heat treatment and brazing is done in accordance with the latest Mil standards. Metal Bellows operates a total of 4 vacuum furnaces to support the heat treatment requirements.
A new state of the art clean line was recently installed which insures that no contaminations are introduced before packaging. This automated system removes organic and inorganic contamination from metal parts using aqueous chemistry and agitation to produce ultra-clean metal parts. Rinse water with a minimum resistivity of 2 Meg-ohms combined with high efficiency dryers assure complete spot free drying.
Since a high percentage of the parts manufactured by Metal Bellows are utilized in a vacuum environment, all bellows welds and assembly welds are checked on state of the art helium mass spectrometer leak detectors strategically placed on the manufacturing floor to minimize travel time (more lean manufacturing at work).
Metal Bellows maintains a complete in-house product testing facility for all aspects of product conformity. Maintaining functional test verification according to required acceptance test criteria consists of mechanical and dimensional verification for individual applications. We maintain a test facility which includes proof pressure and burst test capability, certified non-destructive dye penetrant testing and an environmental test chamber. The lab is staffed by 2 full time metallurgists as well as a staff of trained technicians.
