In this paper, a systematic literature review (SLR) approach has been implemented to show up the research progress on the joining of Nitinol (NiTi) Shape Memory Alloy (SMA) using laser. The properties of NiTi alloy, like the shape memory effect (SME), super-elasticity and biocompatibility, endure it as a desirable material in several high-performance applications. Owing to the extensive use of NiTi SMAs in medical devices, micro-electrical components, aerospace industries etc. joining of this alloy has been a subject of investigation and attracted the attention of the scientific community. Considering its unique characteristics, getting a proper joining of NiTi alloys with self as well as other materials is not only tough but also challenging. Therefore, literature on the advancements in the joining of NiTi alloys is reviewed systematically. Various challenges and ranges of the scope of research during similar and dissimilar joining are addressed and summarized. The weld joint characteristics such as the tensile strength, microhardness, corrosion resistance and microstructural properties are also outlined. Different optimization techniques implemented to obtain the optimum parameter setting during welding and/or machining of these distinctive materials are appraised. The research gaps referred to the domain are identified and deliberated.
