Abstract
Thin wires of Ti-Ni shape memory alloy are welded without fusion or cast zone by the resistance butt welding. The weld current is fed to the butt welded parts with little offset during the time shorter than that in the forging process. The tensile strength of the welded part is attained over 80 percents of that of the base metal. For checking the shape memory effect, the recovery from bending deformation for the welded parts is tested in comparison with that for the base metal, and the residual strain after the recovery is experimentally related to the ratio of latent heat of martenstic transformation to that of reverse transformation, measured by the differential scanning caloriemeter.
