Diseño y construcción de una máquina de soldadura de fricción por aglomeración

Friction welding processes are used in diverse areas such as the naval, automotive, and aerospace sectors. These processes offer great flexibility and energy efficiency in the generation of joints. Friction crush welding is a solid-state joining process in which a rotating tool operates along a joint line between two parts generating frictional heat and mechanical agitation to form a joint. In this work, the design and construction of a friction crush welding machine is presented, the stages included: a) the welding disc design, b) calculus of sheets, c) selection of the motor-screw advancement and d) calculus of the support structure. In the evaluation of the equipment, weld joints of Zn-22% Al-2% Cu (zinalco) and Al A380 alloy were developed presenting weld beads with a continuous material flow.
