Electron Beam Welding Ebw

Ebw is often performed under vacuum conditions to prevent dissipation of the electron beam.

Electron beam welding ebw.

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. Today s aircraft have components that were manufactured using eb welding. Electron beam welding must occur in a vacuum because air molecules interfere with the propagation of the electron beam. A leading edge electron beam welding company since 1966 we partner with our customers to provide high performance quality results.

The vacuum level makes a difference in the quality of the weld. 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. Welcome to electron beam welding. Electron beam welding ebw is another focused beam welding process.

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. Electron beam welding emerged as a production process in the late 1950s within the aerospace and nuclear power generation industries. The power density pd defines the process s ability to develop enough heat for 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.

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. 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.

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. 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. Around the world automobiles on the road have components that were manufactured using eb welding.
