摘　　要：通过选用适当的电子束焊接工艺,可得到4种典型的电子束焊缝形状,分别为钟罩形、漏斗形、楔形和钉形。对不同焊缝形状的电子束焊接接头进行了疲劳性能试验,并利用所建立的层次分析数学模型,综合评价了焊缝形状对疲劳性能的影响。Four different weld shapes are obtained by proper electron beam welding parameters, which are respectively named as bell shape, funnel shape, nail shape, and wedge shape. Fatigue performance examinations of the electron beam welded joints with different shapes are carried out. The influence of weld shape on mechanical performance of the joints is synthetically evaluated by analytic hierarchy mathematical model.
