Shape memory alloys (SMAs) such as nearly equiatomic NiTi find increasing applications in many industries because of their unique functional properties; namely the shape memory effect and pseudoelasticity. There is limited literature on the joining of NiTi SMAs and since their functional properties are extremely sensitive to previous processing history, the effects of the resistance microwelding process on these properties must be better understood. In this work crossed-wire resistance microwelds were characterized for joint strength through tensile testing and insight into the effects of the joining process on the functional properties was gained through thermal-analytical analysis. The pseudoelastic property of the SMA material was also found to have an effect on the contact resistance during the onset of welding current leading to a solid-state joining mechanism.
