It is an excellent process for micro finishing milligram s.
Electron beam welding advantages and disadvantages.
Today we will learn about electron beam welding principle working equipment s application advantages and disadvantages with its diagram.
Electron beam welding is a liquid state welding process.
This brings about a tremendous temperature rise at the point of impact.
Electron beam welding diagram.
Application advantages of electron beam welding.
Liquid state welding are those welding processes in which the metal to metal joint form in liquid or molten state.
Parts 3d printed with ebm have very high density over 99.
Disadvantages of electron beam welding.
Electron beam machining has the following advantages.
Holes of different sizes and shapes can be machined.
With the advantages of the electron beam welding technology can be hard welding metal and welding materials welding depth is big good welding performance welding deformation is small high precision of welding wells with high productivity therefore in nuclear power aviation spaceflight automobile pressure vessel and tool is widely used in manufacturing industries.
Advantages disadvantages advantages of electron beam welding.
The major advantage of electron beam welding is its tremendous penetration which occurs when the highly accelerated electron hits the base metal.
It will penetrate slightly below the surface and at that point release the bulk of its kinetic energy which turns to heat energy.
Ebw is free from potential gas contamination as the welding is done in a vacuum.
A electron gun b power supply c vacuum chamber and d work piece holding device.
Since eb welding is done in a vacuum chamber it prevents the exposure to oxygen that can cause these welds to fail.
With these costs in mind a.
The initial outlay for equipment is expensive.
An ebw set up consists of the following major equipment.
Very small holes can be machined in any type of material to high accuracy.
As the eb welding process takes place in a vacuum the welds are clean and free of oxides and nitrides.
This is particularly an issue with welding titanium if the welds are exposed to oxygen it can cause a serious failure called alpha casing.
