Electron beam welding process pdf.

Ptr is an electron beam welding systems manufacturer and contract welding service provider on the leading edge of electron beam and vacuum welding technology. These electrons are accelerated by applying high potential difference 30 kv to 175 kv between cathode and anode. In which the metal to the metal joint is. In general electron beam welding process is carried out in vacuum.

Principles of electron beam eb welding. Electron beam welding is like laser welding a power beam process ideally suited to the welding of close square joints in a single pass. Electron beam welding is so clever that many people don t appreciate its potential. Applications range from fully automated high productivity and low cost automotive in line part production to single part batch processes in the high cost aircraft engine industry at the other end of the industrial.

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 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. Added to the molten pool during welding to facilitate the process and provide strength to the welded joint.

Electron beam welding is a welding process that uses the heat produced by a beam of high energy electrons electrons hit the workpiece and their kinetic energy is transformed to the thermal energy heating the metal so that the sides of the workpiece can be joined and a weld can be formed after freezing. When no filler metal is used that fusion welding operation is referred to as autogenous weld. 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. In this process electrons are emitted from the heated filament called electrode.

Electron beam welding process is a fusion welding process in which a high velocity electron beam is used to join two metals together. 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. No one has more experience or expertise in the application of electron beam welding than electron beam processes.
