The GTAW process was chosen because it is more economical than the usual welding processes for NiTi alloys, such as the Laser Beam Welding (LBW). The welded joints were characterized by the techniques of SEM, OM, electrical resistance in temperature (ERT), tensile test and Vickers microhardness. It was observed that the dissimilar joints presented a brittle behavior due to the formation of brittle elements along the weld metal by the excessive increase of the hardness in this region with peaks of hardness higher than 900HV. Similar joints presented superior mechanical behavior, with extensive plastic deformation before rupture and fracture surface with ductile appearance. The PWHT in the similar joints promoted a decrease in the rigidity of the material by minimizing the thermal stresses from the welding process, the PWHT did not influence the dissimilar joints mechanical behavior.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"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","url":"https://scielo.figshare.com/articles/Nickel-Titanium_Alloys_Welding_of_Thin_Sheets_Using_GTAW_Comparative_Stu
