节点中的焊接宜采用完全焊透的坡口对接焊缝连接，当采用双面角焊缝连接时，可按等强设计。
And the welding connecting of them are advised to use slope butt weld that are fully welded, but when the double-sided fillet weld is used, they should be design on equal strength.
结果表明，在保证试件完全焊透的情况下，降低电子束的线能量，可在一定程度上提高接头的强度；
Some pores appeared mainly near in the bond line, but porosity can be suppressed to a great extent by increasing welding speed or electron beam scanning.
厚板焊接结构的角焊缝，多数情况下没必要完全焊透，但是，如果未焊透部分尺寸过大，就会使焊接接头的疲劳强度大幅度降低。
There is no need to weld the joint thoroughly for the cruciform joint. But if the dimension which is not welded is too large. that will make fatigue strength reduce.
