Abstract: This paper studies the shape recovery ratio of the welded joints obtained by precision pulse resistance butt welding with the self designed clamp.The research discusses the effect of welding heat,welding press and post heat treatment and cool heat cycle on shape recovery ratio of the welded joints,analyzes the microstructures of the welded joints and obtains the optimum parameters of good shape recovery ratio joint.

Key words: TiNi shape memory alloys, shape recovery ratio, welding parameter
