UHV Quality Welding

Our customers require someone capable of welding aluminum and titanium vessels that perform flawlessly in UHV environments whether that's in a cryogenic chamber, a satellite, or a particle accelerator.

With our long history designing and manufacturing uncommon metals, all our welders are experts in welding challenging materials. They take great pride in laying down perfect stacked dimes as we call it, and address the special heat requirements of aluminum and copper, as well as the more well known stainless protocols.
