The present work aims to investigate the mechanical cycling behaviour of laser welded super elastic shape memory alloys. Butt joints were produced in 1 mm thick plates with different laser welding conditions. The joints were subjected to long term cycling under tensile testing. The superelastic behaviour of welded joints was observed for applied stresses close to about 100 to 150 MPa below the ultimate tensile strength (UTS) of the welds. The functionality was confirmed by analyzing the stabilization of the mechanical hysteretic response and by shape memory tests in liquid nitrogen.
