Tip：Electron beam welding method
Electron beam welding is a welding method that uses the heat energy generated when a concentrated high-speed electron beam bombards the surface of the workpiece. During electron beam welding, the electron beam is generated and accelerated by an electron gun. Commonly used electron beam welding methods include: high vacuum electron beam welding, low vacuum electron beam welding, and non-vacuum electron beam welding. The first two methods are carried out in a vacuum chamber. The welding preparation time (mainly the vacuum pumping time) is long, and the size of the workpiece is limited by the size of the vacuum chamber.
Compared with arc welding, the main characteristics of electron beam welding are large weld penetration, small weld width, and high weld metal purity. It can be used for precision welding of very thin materials and for welding of very thick (up to 300mm) components.
All metals and alloys that can be melt welded by other welding methods can be welded by electron beam. It is mainly used for welding products that require high quality. It can also solve the welding of dissimilar metals, easily oxidized metals, and refractory metals. But it is not suitable for mass production.
