    DESIGN AND CONSTRUCTION OF A FRICTION WELDING EQUIPMENT WITH LASER ASSISTANCE FOR THE JOINT OF AISI 1045 STEEL AND ALUMINUM 2017-T4 SHAFTS
    (2022) Luis Mullo, Jose; Andres Ramos-Grez, Jorge; Omar Barrionuevo, German
    Welding metal alloys with dissimilar melting points make conventional welding processes unfeasible to be used. On the other hand, friction welding has proven to be a promising technology capable of join ring materials, while preventing the temperature from exceeding the melting point. However, obtaining a welded joint with mechanical properties that are similar to the base materials remains a challenge the development of this work, a laser-assisted rotary friction welding equipment was designed and manufactured. A 3 HP conventional lathe was used to provide rotary movement, and a hydraulic pressure system that applies axial force through a Ample effect cylinder was designed to generate friction to obtain the union between the base materiels.
