Electron Beam Welding Ebw

The vacuum level makes a difference in the quality of the weld.

Electron beam welding ebw.

Electron beam welding must occur in a vacuum because air molecules interfere with the propagation of the electron beam. 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 pd in watts per unit area is obtained by the following equation. Electron beam welding ebw is another focused beam welding process.

The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact. The process develops energy by bombarding the work piece with a focused beam of high velocity electrons. The reputation of electron beam welding llc for excellence and competence remains the cornerstone for continued growth. Electron beam welding ebw is a fusion welding in which coalescence is produced by heating the workpiece due to impingement of the concentrated electron beam of high kinetic energy on the workpiece.

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. To impinge on the weld joint and produce coalescence ebw utilizes a moving concentrated beam of high velocity electrons while lbw utilizes the heat from a high density coherent laser beam. Welcome to electron beam welding. Around the world automobiles on the road have components that were manufactured using eb welding.

The higher the vacuum the less amount of contamination and residual gasses will be present when the welding occurs. A leading edge electron beam welding company since 1966 we partner with our customers to provide high performance quality results. Ebw is often performed under vacuum conditions to prevent dissipation of the electron beam. Today s aircraft have components that were manufactured using eb welding.

Electron beam welding ebw is a method of welding in which the energy required to melt the area to be welded is provided by a focussed stream of electrons. The power density pd defines the process s ability to develop enough heat for 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.
