激光焊接是一种适用于形状记忆合金的连接技术。本文报道了形状记忆效应（SME）的存在激光焊接NiTi接头，进行弯曲试验，并与这种效果进行了X射线衍射（XRD）的显微组织分析。所有焊接样品在弯曲至180°后都能够恢复其初始形状，这对于涉及激光焊接的NiTi的工业应用是显著的结果。
Laser welding is a suitable joining technique for shape memory alloys (SMAs). This paper reports the existence of shape memory effect (SME) on laser welded NiTi joints, subjected to bending tests, and correlates this effect with the microstructural analysis performed with X-ray diffraction (XRD). All welded samples were able to recover their initial shape after bending to 180°, which is a remarkable result for industrial applications of NiTi involving laser welding.
