Abstract

PROCEDIMIENTO PARA LA REFUSION CON LASER DE SUPERFICIES METALICAS, EN ESPECIAL DE ARBOLES DE LEVAS. SE CONOCEN LOS PROCEDIMIENTOS DE REFUSION WIG Y TAMBIEN LOS PROCEDIMIENTOS DE REFUSION CON LASER CON UN FOCO RECTANGULAR. SIN EMBARGO, EN ESTE ULTIMO SE PRODUCE LA REFUSION EN VARIOS PASOS. EL INVENTO PRETENDE ACORTAR LOS CICLOS E INCREMENTAR ADICIONALMENTE LA RENTABILIDAD. EL PROCEDIMIENTO, SEGUN EL INVENTO TRABAJA IGUALMENTE CON UN RAYO LASER CON FORMA RECTANGULAR, CUYA LONGITUD SE EXTIENDE, SIN EMBARGO, SOBRE TODO EL ANCHO DE LA SUPERFICIE DE LA PIEZA Y CON ELLO DE LA LEVA 11. LA DENSIDAD DE POTENCIA Y LA VELOCIDAD RELATIVA ESTAN AJUSTADAS PARA OBTENER UNA DETERMINADA PROFUNDIDAD DE REFUSION. FABRICACION DE ARBOLES DE LEVAS PARA MOTORES DE PISTONES.
