Difference Between Ebm And Lbm Electron Beam Laser Beam

Laser Beam Machining An Overview Sciencedirect Topics

Electron beam machining is process in which high velocity electrons are concentrated in a narrow beam and then directed towards the workpiece for machining.

Electron beam and laser beam machining. In fact an electron beam welding system can throw enough power to simply vaporize metal a process called electron beam machining. When this high velocity electron strikes the workpiece it melts and vaporizes the material from the workpiece. This will generate high heat energy and melts and vaporize metal from work piece. Laser beam machining lbm process utilizes a coherent beam of laser photons having same frequency wavelength and phase as the heat source for material removal purpose. It is mostly used to drill holes in any shape. Electron beam machining is the metal removal process by a high velocity focussed stream of electrons which heats melts and vaporizes the work material at the point of bombardment. In an electron beam machining the electrons strike the. Laser beam machining produces large re melt zone can produce holes as small as 00005 mm diameter can produce deep holes used to produce cooling holes in bladesvanes for jet engines. Electron beam machining is same as laser beam machining process in which except laser high speed electron beam impinges on work piece. Laser light amplification by stimulated emission of radiation is basically a coherent and amplified beam of electromagnetic radiation. This whole process takes place in vacuum chamber. But which process is the most effective. Electron beam welding ebw and laser beam welding lbw are two very popular methods of joining multiple metallic components. Laser beam machining flash lamp reflective end laser crystal partially refiective end lens generator workpiece. The answer to this question depends on the welding application.

The power delivered by an electron beam can be massiveto 10000 kwmm 3.

Eb welding machines generally come in two power classifications low voltage 60 kv or high voltage 150 kv.
