Electron Beam Welding Ebw

The kinetic energy of each electron is given by mv 2 but v that is the electron velocity is proportional to the square root of the accelerating volt age so the energy of each electron is proportional to the accelerating voltage.

Electron beam welding ebw.

Electron beam welding ebw is another focused beam welding process. Since then it has become a preferred technique for small precision parts requiring very high quality welds in low carbon steel stainless steel aluminum titanium inconel and many other exotic alloys. The electron beam welding ebw and laser beam welding lbw processes are high energy density welding processes that offer several possible advantages including low welding heat input high weld depth to width ratio narrow heat affected zone haz and reduced distortion. Around the world automobiles on the road have components that were manufactured using eb welding.

Electron beam welding emerged as a production process in the late 1950s within the aerospace and nuclear power generation industries. The vacuum level makes a difference in the quality of the weld. A leading edge electron beam welding company since 1966 we partner with our customers to provide high performance quality results. The process develops energy by bombarding the work piece with a focused beam of high velocity electrons.

The pd in watts per unit area is obtained by the following equation. The power density pd defines the process s ability to develop enough heat for welding. Electron beam welding must occur in a vacuum because air molecules interfere with the propagation of the electron beam. The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact.

The higher the vacuum the less amount of contamination and residual gasses will be present when the welding occurs. High power electron beam systems for welding and drilling are used in the aerospace automotive defense semiconductor medical nuclear oil gas power generationand a variety of other industries. Today s aircraft have components that were manufactured using eb welding. The reputation of electron beam welding llc for excellence and competence remains the cornerstone for continued growth.

Ebw is often performed under vacuum conditions to prevent dissipation of the electron beam. Welcome to electron beam welding. Electron beam welding ebw is a fusion welding process in which a beam of high velocity electrons is applied to two materials to be joined.
