Determinación del tiempo en la etapa de calentamiento para obtener la unión de un aluminio AA 6063 soldado por fricción

Friction Welding (FRW) aims to achieve joints in materials with cylindrical profiles that cant be welded conventionally. The objective of this resear ch was to determine the time at stage of warming to achieve link bars of aluminum AA 6063 soldier by FRW. Tests were performed at different times of warming, whil e maintaining constant pressure and speed. It was det ermined that more time at the stage of warming produces greater friction between the bars which causes more plastic deformation and increase the percentage of union. On the other hand, the time range in the stage of warm ing earning higher percentage of union is between 1 40 and 180s, reaching the full union of the rods to 160s, also the variation of the mandrels advance at the stage of forged produces a not significant increase in the percenta ge of union.
