| Abstract: | 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.Mechanical performance of the electron beam welded joints with different shapes were carried.The influence of weld shape on mechanical performance of the joints was synthetically evaluated by analytic hierarchy mathematical model.The results show that weld shape effects tensile property,fatigue property and microhardness of the joint.The sequencing of mechanical performance of the joints with four different shapes by analytic hierarchy process is hell shape,funnel shape,wedge shape,and nail shape.It is validated by experimental results that the analytic hierarchy mathematical model is effective and practical. |
| Keywords: | weld shape electron beam welding mechanical performance analytic hierarchy process |
