What does Invacua do?
Precision Welding
Precision Pulsed TIG Welding is ideal for joining small components that are heat sensitive and require a joint that is hermetic and mechanically sound.

Vacuum & Induction Brazing
Vacuum Furnace Brazing is the most cost-effective method for joining precision components in corrosion and heat resisting materials. Induction brazing heat is localised to the joint area.

A few years back Invacua brazed together a copper bracket which was used to hold sensitive equipment on the Plank spacecraft. Planck was Europe's first mission to study the Cosmic Microwave Background, the relic radiation from the Big Bang, which occurred about 14 thousand million years ago. The mission had a wide variety of scientific aims, including: [5] high resolution detection's of both the total intensity and polarization of primordial CMB anisotropies, creation of a catalogue of galaxy clusters through the Sunyaev–Zel'dovich effect , observations of the gravitational lensing of the CMB, as well as the integrated Sachs–Wolfe effect , observations of bright extragalactic radio ( active galactic nuclei ) and infrared (dusty galaxy) sources, observations of the Milky Way , including the interstellar medium , distributed synchrotron emission and measurements of the Galactic magnetic field , and studies of the Solar System , including planets , asteroids , comets and the zodiacal light . Plank made it's last communication with earth on the 23rd October 2013. Where is it now? Planck now orbits the second Lagrange point of our Earth-sun system, about 1.5 million km (930,000 miles) away.
We dug out an old copy of What's New In Industy magazine from 1991 and on the front is a picture of Invacua's Brian performing some vacuum brazing.
Great article here from AZO material describing the benefits of induction brazing over flame or vacuum brazing https://www.azom.com/article.aspx?ArticleID=13360
