Welding also known as gas welding, brazing. PMA and other ion brazing machine, completely replace the traditional brazing equipment, a new generation without oxygen, acetylene, liquefied petroleum gas, alcohol, gasoline, combustible gas brazing equipment. The IGBT inverter control principle, welding, the flame is very stable, the entire device is lightweight and convenient for Welding Wires. The welder simple Little welder people can not require special training, the product does not need to acetylene and other flammable fried gas, and greatly improve the safety performance. Just electricity, some less developed regions (without oxygen or acetylene, gasoline, etc.) use of ion braze welding advantage is obvious. Welding process, the direct use of gas flux instead of the traditional manually add the borax, to improve the wettability and fluidity of the brazing in order to reduce the formation of pores. Improve the tensile strength of the weld, the CO2 Gas Shielded Welding Wire, surface oxidation, not black. Does not require pickling, greatly improving the efficiency of access efficiency.
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.
