提出了一种异种材料搭接钢铝接头的新工艺，并进行了试验。将一个简单的圆柱形工具旋转并平移到顶部钢板上，导致底部铝板瞬间部分熔化，形成厚度为2.5 μm的feal3和fe2al5金属间反应层。搭接剪切试验表明，焊缝具有良好的抗断裂性能，主要发生在母材中。
A new lap welding process for dissimilar materials has been developed and tested for steel-to-aluminium joints. A simple cylindrical tool is rotated and translated over the top steel plate, leading to a transient partial melting of the bottom aluminium plate and the formation of intermetallic reaction layers of FeAl3and Fe2Al5as thin as 2.5 μm. Lap shear tests of the welds show very good resistance with fracture mostly in the base materials.
