Laser welding technology is a more appropriate way in the processing of shape memory alloy. The mechanical properties and shape memory properties of the base metal and weld are tested, The comparison of the mechanical properties between the base metal and the laser weld is studied, and draw the conclusion. The mechanical properties are studied by temperature stress-strain test. The results show that stress-induced martensite changes little, the recovery mechanism of shape memory property is little affected by laser welding, and the laser welding method affects the properties of alloy weld to a small extent.
