引言电渣焊接是一种新的,有巨大发展前途的熔剂层下焊接的方法。不过,这种焊接过程的实质与一般熔剂层下电弧焊接过程的实质不同,它建筑在“熔化的熔渣由於它的构造离子本质而具有一定的导电性”的基础上。在焊接过程中,基本金属边缘和焊丝的熔化,是借助於电流通过复盖在液体金属熔池上的熔化熔渣所析出的大量电阻热。因此供电渣焊用的熔剂就负有特殊的使命,其性能对电渣焊接过程发生决定性的影响。为了使焊接过程顺利地进行,从而获得令人 Introduction Electroslag welding is a new, promising method of flux layer welding. However, the essence of this welding process is essentially different from the arc welding process generally carried out on flux floor, which is based on the principle that “molten slag has a certain electrical conductivity due to the nature of its constructed ions.” During the welding process, the base metal edges and the welding wire are melted by means of a large amount of resistance heat which is precipitated by the current passing through the molten slag covering the liquid metal bath. Therefore, the flux used for power supply welding slag has a special mission, the performance of the electroslag welding process has a decisive impact. In order to smooth the welding process, which is amazing
