Abstract

La presente invencion se refiere a en un método para soldar eléctricamente juntas un par de porciones de borde de una parte o partes metálicas que tienen superficies opuestas en las cuales dichas porciones de borde tienen superficies de borde y son avanzadas hacia un punto de soldadura con dichas superficies de borde en una relacion opuesta y espaciada delante del punto de soldadura pero que se unen juntas en dicho punto de soldadura, dichas superficies de borde se calientan hasta la temperatura de soldadura al momento en el cual alcanzan dicho punto de soldadura por medio de corrientes eléctricas de alta frecuencia inducidas en el metal de dicha parte o partes y que fluyen, en cualquier momento dado, en una direccion en una de dichas superficies de borde y en la direccion opuesta en la otra de dichas superficies de borde, la mejoría comprende: la induccion de un par de dichas corrientes de alta frecuencia por al menos dos bobinas de induccion, una de dichas bobinas se coloca en un lado de dicha parte o partes metálicas y la otra bobina se coloca en el lado opuesto de dicha parte o partes metálicas y una de dichas dos corrientes inducidas por una de dichas bobinas fluye en la misma direccion que la otra de dichas dos corrientes inducida por dicha otra bobina en cada una de dichas superficies de borde.
