Laser Beam Welding Low Vacuum Purge Chamber

Laser Beam Welding Low Vacuum Purge Chamber sitting on a pallet
This was actually not a vacuum chamber per se but more like a vacuum purge unit. Our customer, who is from academia. had gotten a custom made CNC laser beam welding unit. They were looking for a way to purge the surrounding air and fill it with inert gas in order to prevent oxidation and contamination from the laser heat source. We suggested several small chambers with a viewport for their laser welder. However, they wanted to encase the whole CNC unit inside a chamber which would be lift able by a crane for easy access.

After going back and forth with us trying to talk them out of getting such a large chamber and encasing the whole unit, we finally agreed because they were only looking to purge the air out and inject argon; hence this unit would never go below a gauge vacuum of - 3psi.

What you see here is a vacuum purge chamber for a CNC laser welder with dimensions of 28 inch wide, 30 inch deep, and 35 inch high. The whole chamber sits on an aluminum plate that has clamps in order to clamp down the chamber during the purging process. We also added a lifting holes and reinforcement ribs for structural robustness in case one of their graduate students forgets to turn off the vacuum pump...

Vacuum Oven Systems
Vacuum Ovens are vacuum chambers and ovens combined in one system. Vacuum ovens are necessary during processes which require the specimen to be subjected to a hypobaric and hyperthermal environment. Our Vacuum Oven Systems enable to you run a complete vacuum vs time and temperature vs time profile. We also carry portable vacuum oven systems and custom vacuum oven systems.
Viewport Vacuum Feedthroughs
Viewports Vacuum Feedthroughs are windows that enable you to look into the inside of your vacuum chamber. If you are using a metallic vacuum chamber with a metallic lid, you will not be able to view the interior of your vacuum chamber unless you have a viewport. Viewports also enable a different electromagnetic spectrum of light to passthroughs.
Our Work: Chamber for Vacuum Extrusion System
This is a custom acrylic vacuum chamber build for a high volume manufacturer of parts which are fabricated using vacuum extrusion techniques. The challenge was to build a vacuum chamber system which mated on two perpendicular surfaces; on the bottom and on the rear of the chamber. This was accomplished by incorporating a double gasket mechanism on the bottom and incorporating a clamping mechanism on the rear.

Bubble Leak Testing or Bubble Emission Testing is a procedure where leaks are visually detected and located through the emission of bubbles while the test specimen is submerged in water. In this article, we will talk about using an acrylic vacuum box as a leak detection device. We are also going to talk about the advantage, disadvantage, and the bubble leak emission test procedures.
