焊接过程电弧稳定，焊接接头熔合良好，未见裂纹、 未焊透、夹渣、 气孔等缺陷。

This process showed a stable arc, good welding joints without any gas pores and cracks.

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.
