Electron beam welding

Electron beam weldingis a method of welding using the heat generated by accelerated and focused electron beam bombardment of weldments placed in vacuum or non-vacuum.Electron beam welding is widely used in many industries such as aerospace, atomic energy, national defense and military industry, automobiles, electrical and electrical instruments because of its advantages of no welding rod, not easy to oxidize, good process repeatability and small thermal deformation.

 

▲The principle of electron beam welding

The electron beam penetration ability is strong, the power density is extremely high, and the welding seam aspect ratio can reach 50:1, which can realize the one-time forming of large thickness materials, and the maximum welding thickness can reach 300mm. Good welding accessibility, high welding speed, generally above 1m/min, small heat-affected zone, small welding deformation, and high welding structure accuracy. The electron beam energy can be adjusted, and the thickness of the metal to be welded can be as thin as 0.05mm to as thick as 300mm. It can be welded at one time without beveling, which is not achieved by other welding methods. The range of materials that can be welded by electron beam is large, and it is especially suitable for welding active metals, refractory metals and workpieces with high quality requirements.
