The welding of shape-memory alloys is a challenge due to the fact that there are numerous compositions and because the properties are greatly influenced by the temperature.
Pulsed laser welding is a solution used for joining NiTi shape-memory alloys, having the advantage of localized heating and the possibility to adjust the welding parameters to obtain optimal properties.
Industry requirements for more complex structures have led to the study of methods for joining these smart materials that could have as low as possible influence on the properties of the base alloy.
Because it is essential to limit as much as possible the undesirable effects of the laser beam on the laser-welded SMA's properties, precise control of all parameters involved in the welding process is necessary.
The use of laser equipment that works in a pulsed mode has the advantage of localized heating, but especially the possibility of adjusting the process parameters to obtain optimal properties.

IN718 alloy possesses excellent mechanical properties at high temperatures, good process ability, therefore, it has been widely used in aero engine turbine disks, compressor disks, and power turbine shafts (i.e., rotating components).
The fatigue properties of the alloy are a key factor that determines the safety and reliability of the engine.
The grain size is smaller, and the low cycle fatigue properties of the alloy are better.
Among the Ni-base superalloys, IN718 is predominantly used in high-temperature applications due to its highly satisfactory price/overall performance ratio, good corrosion resistance and mechanical properties with excellent weldability.
