| Abstract: | Many methods of studying typical character of electron beam welding(EBW) welds shape had been introduced,including experiments,theoretic analytics,numerical simulation,Regression analysis and artificial neural network.The results showed it was reasonable scheme,which combined several methods to study welds shape.There were a lot of key points gained from weld figure,and parameterize recurrence were achieved by B-spline curves to connect these points.The relationship between parameter for key point and that ... |
| Keywords: | EBW shape character geometric keypoint parameterize recurrence classifying criterion |
