(1) generated by electron beam welding, electron beam welding is a focus on high-speed electron beam bombardment of the surface of the heat welding method. Electron beam welding, electron beam generated by the electron gun and accelerated. Commonly used in electron beam welding include: high-vacuum electron beam welding, low-vacuum electron beam welding and non-vacuum electron beam welding. The first two methods are in the vacuum chamber. Welding Electrode Materials (mainly vacuum time) is longer, the size of the workpiece by the vacuum chamber size limits. Electron beam welding and  Welding Electrode, the main features of the weld penetration, weld width is small, the weld metal of high purity. It can be used in the precision welding of thin materials can be used on very thick (most thick 300mm) component soldering. All other welding methods for fusion welding of metals and alloys using electron beam welding. Mainly used for welding requirements of high-quality products. Can solve the dissimilar metal, easily oxidized metal and the welding of refractory metals. But not suitable for a large number of the amount of product.
(2) laser welding Laser welding is the use of high-power coherent monochromatic sub-streams focused laser beam from the heat source for welding. This welding method is usually a continuous power laser welding and pulsed power laser welding. The advantages of laser welding is not required in a vacuum, the disadvantage is that the penetrating power than the strong electron beam welding. Accurate energy control, laser welding, the welding of precision miniature devices which can be achieved. It can be applied to many metals, in particular, is able to solve some difficult to weld metals and welding of dissimilar metals.
