Ruiling, Dongsheng, RuiLong, Fiberhome, Ruicheng, Blu-ray, Welding King, etc., are good, TIG welding machine dosage are not big, are good.
It and tungsten argon arc welding difference: one is the wire as the electrode, and is constantly melting to fill the molten pool, condensing to form a weld; the other is the use of shielding gas, with the application of fusion electrode argon arc welding technology, the shielding gas has been developed from a single argon a variety of gas mixtures are widely used, such as Ar 80% + CO220% of argon-rich shielding gas.
Often the former is called MIG, the latter is called MAG. from its mode of operation, the most widely used is the semi-automatic melting electrode argon arc welding and argon-rich mixed gas shielding welding, followed by automatic melting electrode argon arc welding.
Non-molten Argon Arc Welding:
Non-molten Argon Arc Welding is a non-molten arc in the non-molten electrode (usually tungsten) and the workpiece between the combustion of the weld arc around the flow of an inert gas (commonly used argon) does not have a chemical reaction with the metal, the formation of a protective gas shield, so that the tungsten electrode end, the arc and the molten pool and has been in the high-temperature metal Not in contact with air, can prevent oxidation and absorption of harmful gases. Thus forming a dense welded joint, its mechanical properties are very good.
Molten Argon Arc Welding wire fed through the wire wheel, conductive nozzle conductive, between the base material and the wire to produce an arc, so that the wire and the base material melted, and with the inert gas argon to protect the arc and the molten metal to carry out the welding.
