Electron beam welding process pdf.

Electron beam welding is so clever that many people don t appreciate its potential. These electrons are accelerated by applying high potential difference 30 kv to 175 kv between cathode and anode. Aws c7 1m c7 1 2013 recommended practices for electron beam welding and allied processes is the third revision 4th edition of the document issued initially in 1992. This edition adds three new practical examples and adaptations of the electron beam process including electron beam braze welding ebbw electron beam cutting ebc and drilling.

The ebm is also a liquid state welding process. In this process electrons are emitted from the heated filament called electrode. No one has more experience or expertise in the application of electron beam welding than electron beam processes. To find out more call us on 0844 2414257.

The high velocity electron beam when strikes the weld area of two metal pieces and very intense heat is generated which melts the metal and they fuse together to form a strong weld. Unlike the laser beam however the electron beam process utilises a vacuum chamber in which is generated a high energy density beam of electrons of the order of 0 25 2 5 mm in diameter fig. In general electron beam welding process is carried out in vacuum. The electron beam eb welding process is used in a variety of industries.

Principles of electron beam eb welding. In addition to making eb and laser welding equipment ptr assists customers with weld process development and provides maintenance and spares support for electron beam welding systems. Ptr is an electron beam welding systems manufacturer and contract welding service provider on the leading edge of electron beam and vacuum welding technology. When no filler metal is used that fusion welding operation is referred to as autogenous weld.

Electron beam welding process is a fusion welding process in which a high velocity electron beam is used to join two metals together. Arc welding resistance welding oxyfuel gas welding electron beam welding laser welding r. Electron beam welding is like laser welding a power beam process ideally suited to the welding of close square joints in a single pass.
