Vacuum Furnace

Vacuum Furnace

A vacuum furnace is a type of furnace in which the product in the furnace is surrounded by a vacuum during processing. The absence of air or other gases prevents oxidation, heat loss from the product through convection, and removes a source of contamination. Vacuum furnace is used to carry out processes such as annealing and heat treatment with high consistency and low contamination.

Glass to Metal sealing

The Glass-to-metal sealing is to hermetically pass a conductor from one environment to another. That conductor may conduct electricity, light or gases.

The glass used in glass to metal sealing provides the hermetic seal and as glass is an excellent insulator is often also used to provide electrical isolation

Electron Beam Welding

Electron beam welding is a fusion welding process in which high velocity electrons beam is applied on two materials to be joined. The material are melted due to the kinetic energy of the electrons which transforms into heat upon impact on the Joint. However, because the electron beam is tightly focused, the total heat input is actually much lower than that of any arc welding process.

Almost all metals can be welded by the process, but the most commonly welded are stainless steels, superalloys, and reactive and refractory metals.

 

The process is also widely used to perform welds of a variety of dissimilar metal combinations. Electron Beam Welding is a very similar process to Laser Beam Welding, except that electrons are focused instead of photons in the case of lasers.

The Electron beam welding carried out in Vacuum atmosphere, controlling the work piece from oxidation.

Few advantages of EB welding are

  • Minimal post weld machining
  • Minimal distortion
  • Narrow and small HAZ
  • Deep weld penetration from 0.5 to 12 mm in a single pass ( LTE Machine)
  • Low heat input for the joined parts, normally no filler metal needed, metals can be welded with dissimilar melting points
  • All metals can be welded, even those with high thermal conductivities
  • High welding speed
  • Vacuum process results in clean, reproducible environment
  • Our capability
  • Linear weld upto 200 mm
  • Circular weld up to 250 mm diameter
  • Maximum loading :- 20 kg for Face welding , 10 Kg for circular welding
  • Depth of penetration :- 12 mm
