Abstract
Procedimiento de conformación en caliente de una cabeza de válvula a partir de una varilla, que consiste en calentar esta varilla y en aplicar uno de sus extremos sobre un yunque según un penetración progresiva para conformarla según una cabeza aproximadamente hemisférica, caracterizado porque se efectua el caldeo por medio de un inductor dispuesto coaxialmente a la varilla, y porque se desplaza progresivamente el inductor en sentido contrario a la penetración de la varilla.
