Electron beam welding was developed by the german physicist karl heinz steigerwald in 1949 who was at the time working on various electron beam applications. Steigerwald conceived and developed the first practical electron beam welding machine which began operation in 1958.

1 history electron beam machining ebm discovery that a beam of electrons has ability to melt materials coincided with the discovery of x raytube in late 1800s in 1940s individuals of manufacturing community began to consider the possibility of using electron beam for performingvarious fabricationtasks.

History of electron beam machining. Through introduction of the principle and characteristics of electron beam machining technology the application status and application instance of electron beam in research of materials science and materials processing in recent years were introduced in detail. Electron beam machining equipment the basic functions of any electron beam gun are to generate free electrons at the cathode accelerate them to a sufficiently high velocity and to focus them over a small spot size. Russell has also been credited with designing and building the first electron beam. The cathode is generally made of tungsten or tantalum. Electron beam machining does not apply any cutting force on the workpiece thus very simple work holding is required. The research situation of the previous various electron beam machining methods and applications was discussed and the various. American inventor james t. What had to be laboriously worked out at that time is taken for granted today. The beam cross section is then focused and directed toward the work piece creating heat and vaporizing the material. Karl heinz steigerwald built the first electron beam processing machine. 1952 is seen as the dawn of electron beam technology. Further the beam needs to be manoeuvred if required by the gun. Ebm can be used for very precise cutting or boring of a wide variety of metals. As electron beam machining is grouped under the thermal category it is natural to have thermal damages as part of the result. Electron beam machining can be used to accurately cut or bore a wide variety of metals.

This is why machining fragile and brittle materials is obtainable using this method. The history of electron beam technology began with the experiments by physicists hittorf and crookes. Electron beam machining is a process in which high velocity electrons are concentrated into a narrow beam with a very high planar power density. Electron beam machining ebm is a process where high velocity electrons concentrated into a narrow beam are directed toward the work piece creating heat and vaporizing the material.
