利用传统的电子束焊接机，在抑制热影响区（HAZ）的焊接条件下，实现了Zr 50 Cu 30 Ni 10 Al 10块状玻璃板的电子束焊接。为了获得足以形成玻璃的冷却速率，焊接速度应控制在100mm /s以上，光束辐射面积应限制在直径小于0.8 mm。焊接大块玻璃板的接头强度约为1400 MPa，比玻璃合金的抗拉强度（1650MPa）低15%。焊接合金板沿焊接区域的剪切滑移面发生断裂，反映了Zr 50 Cu 30 Ni 10 Al 10大块玻璃合金焊接区域具有良好的延展性。
By using a conventional electron beam welding machine, an electron beam welding of Zr 50 Cu 30 Ni 10 Al 10 bulk glassy plates has been achieved in the welding condition leading to the suppression of heat affected zone (HAZ). In order to obtain the cooling rate, which is sufficient for glass formation, the welding speed was controlled to be higher than 100 mm/s and the beam-radiated area should be limited to be smaller than 0.8 mm in diameter. Joint strength of the welded bulk glassy plate is about 1400 MPa, which is lower by 15% than the tensile strength (1650MPa) of the glassy alloy. The fracture of the welded alloy plate occurs along shear slip plane across the welded area, reflecting good ductility in the welded area of the Zr 50 Cu 30 Ni 10 Al 10 bulk glassy alloy.
