    Effect of laser welding speed on pore formation in AA 6061 T6 alloy
    (Carl Hanser Verlag, 2020) Is, Emine Gundogdu; Topuz, Polat; Akman, Erhan; Yilmaz, Muharrem
    In this study, 6 mm thick plates of Al 6061 T6 alloy are joined by laser welding at four welding speeds (40 mm x s(-1), 35 mm x s(-1), 25 mm x s(-1), and 20 mm x s(-1)). The welded joints are made using a 4000 W fiber laser welding machine. The effect of laser welding speed on the pores formed in the weld seam was investigated. In this manner, it was found that with a change in laser welding speed the amount of pores formed in the structure also changed. In addition, after the welding process, macroscopic examinations, tensile tests and the hardness tests were made. As a result of the experiments performed, it was determined that, the laser welding speed was highly effective for pore formation.

    Effects of different profiled pins used in friction stir welding of Al 6061 T6
    (Walter De Gruyter Gmbh, 2023) Is, Emine Gundogdu; Kocak, Kadir; Basar, Zeynep Sueda; Yavuz, Yagizer; Topuz, Polat
    In this study, Al 6061 T6 alloy was joined by friction stir welding method with the same parameters using with different profiled pins. As a result of the experiments carried out, the samples were subjected to metallographic examination, hardness measurements, tensile test and bending test. As a result of the examinations carried out, changes in welding performances were determined with the change of pin profiles. As a result of these changes, it was determined that the pin profile suitable for the applied welding parameters was pyramid. It has been concluded that in the use of triangular profile pins, the welding parameters in question should be higher, and the most important reason for this is that the stir zone is larger.
