1, is the category welding material and performance requirements for welded joints
Low carbon steel welding materials should be selected to match with the base material. Optional high Meng high silica flux (eg HJ431, HJ433, HJ430); with low carbon steel wire (such as H08A) or manganese wire (such as H08MnA) compatible. Or manganese, low or no manganese manganese and manganese content is higher flux wire match.
2, submerged arc welding process characteristics
Most of the dilution rate of the base metal component weld composition
High heat input should be selected alloy composition and slightly higher than the base metal wire with neutral flux
Welding speed should choose a suitable rapid welding flux
