苏联巴頓电焊研究所已基本解决了大断面球墨鑄铁的板極电渣焊。供研究用的球墨铸铁鑄板尺寸为100×400×500公厘,板極断面为18×100公厘。焊接时用AHφ-6熔剂(70％CaF_2+30％Al_2O_3)。对100公厘厚的焊接接头用三种單位能量不同的焊接規范(見表1)进行 The Soviet Union Barton Welding Institute has basically solved the large cross-sectional ductile iron plate welding. The size of ductile iron castings for research purposes is 100 × 400 × 500 mm and the plate section is 18 × 100 mm. AHφ-6 flux (70% CaF 2 + 30% Al 2 O 3) was used for welding. For 100 mm thick welded joints with three different welding energy specifications per unit (see Table 1)
