Abstract

Un procedimiento para preparar una pasta de unión de metales, en particular adecuada para el soldeo de precisión con soldadura blanda y con soldadura fuerte, o para infiltración, caracterizado porque se prepara un vehículo de pasta, mezclando, a una temperatura elevada, ingredientes de la pasta, que incluyen disolvente, fundente y aditivos especializados; enfriar dicho vehículo y mezclar polvo metálico con él; teniendo lugar el mezclado sin una exposición importante del metal en polvo a la acción del vehículo a una temperatura elevada, y realizándose el enfriamiento hasta una temperatura que inhiba cualquier reacción importante del polvo metálico con el vehículo, así como en condiciones de enfriamiento de choque.
