Dissimilar Metals Laser Joining Optimized in Mechanics and Processing Approach with Simulation

许多行业都需要异种材料连接。但由于材料学、工艺学和力学等方面的问题，难以获得强度上具有较高可靠性的接头。研究了界面金属间相的形成及熔池形状对接头强度的影响。为了详细研究熔池形状对焊接性能的影响，采用模型接头进行了试验考虑，并进行了有限元分析。

Dissimilar materials joining is required in many industries. However, it is difficult to obtain the joint with higher reliability on its strength due to the problems on materials science, processing and mechanics. In this study, effects of formation of intermetallic phase at the interface and weld pool shape on strength of the joint were studied. In order to investigate particularly the effect of weld pool shape, experimental consideration by using the model joints and FEM analysis have been done.
