Laser WeLding of Ta15 TiTanium aLLoy and inconeL 718 dissimiLar meTaLs this paper studied the effect of laser welding technology on dissimilar metal welding joints of tA15 titanium alloy and inconel 718 nickel-based alloy.the research results indicate that the laser welding of tA15 titanium alloy and inconel 718 nickel-based alloy directly was difficult to form well, which due to the intermetallic compounds caused the joint brittle.When the pure Cu foil was used as the filling layer, the quality of the welding joints can be improved effectively.the experimental results also indicate that there were brittle intermetallic-compounds in the laser welding seam, and the laser power had an important influence on the performance and mechanical properties of the dissimilar metal joint.the maximum average tensile strength of the welding joint of 2300 W was increased to 252.32 MPa.Scanning electron microscope(SeM) results show that the fracture morphology was river pattern, a typical morphological of cleavage fracture, and the mode was brittle fracture.
