Abstract

Un método de corte por láser para una tira de acero de acuerdo con la presente invención incluye el corte de un extremo en dirección de la anchura de la tira de acero que incluye una junta obtenida mediante la unión de un extremo trasero de una tira de acero anterior y un extremo frontal de una tira de acero posterior mediante el uso de un rayo láser, en el que la tira de acero se corta de tal manera que un intervalo entre piezas de escoria que tienen una relación de aspecto de 1.0 o más se establece en 1.0 mm o más y un intervalo entre la escoria que tiene una relación de aspecto de 1.0 o más y la escoria que tiene una relación de aspecto de menos de 1.0 se establece en 1.0 mm o más en el extremo en la dirección de la anchura después del corte.
