   1) structural steel welding wire is generally low-carbon steel welding wire used H08A; important low carbon steel weldment H08Mn and H08MnA; in strength weldments with H15A; high strength weldments H15Mn. The weld strength rating of 300 to 350MPa of ordinary carbon steel, using the H08A, H08Mn, and H08MnA wire. Welding quality carbon steel and low alloy structural steel, can be carbon structural steel welding wire or alloy structural steel Welding Electrode , such as H08Mn, H08MnA, H10Mn2 and H10Mn2MoA and so on. 2) cast iron cast iron wire using wire into the wire of the gray cast iron and alloy cast iron wire, the model, the chemical composition can be found in the relevant national standards.
(2) the role of Gas Shielded Welding Wireprocess of welding flux) gas welding flux, the oxygen in the molten metal is heated easily with the surrounding air or flame oxidation connate oxides, weld defects such as pores and slag. In order to prevent oxidation and elimination of metal oxides formed in the welding of non-ferrous metals, cast iron and stainless steel and other materials must be using gas welding flux. 2) commonly used in gas welding flux, and the selection of gas welding flux should be based on the type of base metal oxides in the gas welding process selection. The selection of the flux should be able to dissolve these oxides.
