10 什么是电子束焊 ?有何特点与用途 ?电子束焊属高能焊 ,是当今提倡发展的三束技术 (电子束、激光束、等离子束 )之一。电子束焊是利用汇聚的高速电子流轰击工件接缝处所产生的热能使金属熔合的 1种焊接方法。电子束作为焊接热源有 2个明显特点 :(1)功率密度高。电子束焊接时
10 What is electron beam welding? What are the characteristics and uses? Electron beam welding is a high energy welding, is today advocated the development of the three beam technology (electron beam, laser beam, plasma beam) one. Electron beam welding is the use of converging high-speed electron flow bombardment of the seam at the heat generated by the metal welding of a welding method. E-beam as a welding heat source has two distinct characteristics: (1) high power density. Electron beam welding
