电子束的物理特性使99%的电子束能量转化为热能成为可能。这种高度的能量传递效率能力，加上直接在大气中进行电子束焊接产生的束流扩散，允许低成本接头制备的生产公差。不同的焊接实例证明了该工艺的能力。

The physical characteristics of an electron beam makes possible a 99% transformation of beam energy into heat. This high degree of energy transfer efficiency capability, coupled with the beam diffusion that results from EB welding directly in atmosphere, allows production tolerances of low-cost joint preparations. Different welding examples demonstrate the capability of this process.
