AH-25导电焊剂用于电渣铸锭、接触电渣焊、板极电渣焊及铸件电渣焊开始阶段激发电渣过程之用。这种焊剂具有下列优点:(1)铸件电渣焊时可以不必用碳极先造成渣池,避免产生白口;(2)垫板厚可为15公厘而不被击穿和产生缺肉、焊不透、夹渣等焊接缺陷;(3)引弧时减少板极与母材因短路而产生的粘结现象;(4)板极可以不必削尖。 AH-25 conductive flux for electroslag ingot, contact electroslag welding, plate electrode electroslag welding and electroslag welding start electroslag welding process used. This flux has the following advantages: (1) castings electroslag welding can be used without carbon slag first to create slag pool, to avoid white; (2) pad thickness can be 15 mm without breakdown and the lack of meat , Welding impermeable, slag and other welding defects; (3) reduce the plate when the arc and parent metal due to short-circuit bonding phenomenon; (4) the plate can not be sharpened.
