Abstract：High voltage electron beam frame process of TC4-DT material is studied. High voltage electron beam
welding technology is used to realize the hot forming process of refractory metal with complex structure and large thickness,
and the process, microstructure, mechanical properties and microstructure are analyzed systematically. The experimental
results show that the formation of the electron beam is relatively flat, the shape is narrow, the tensile and impact
strength are higher, and the tensile strength is stronger than that of the base metal, but the impact toughness is decreased.
Meanwhile, the weld joint microstructure of lamellar structure has no obvious boundaries, which ensure the continuity of
weld microstructure, and grain refinement, staggered.
