Tungsten Molybdenum Alloy Energized Electrodes For TIG Welding Machine


1. Description of Tungsten Molybdenum Alloy Energized Electrodes For TIG Welding Machine:


Tungsten molybdenum electrodes are made of tungsten and molybdenum and are produced using the same processes as those used to make molybdenum and molybdenum alloys. This allows us to produce electrodes in a variety of shapes, including rods, plates, wire, and other custom designs.


Low thermal expansion coefficient, high temperature strength, low vapor pressure, wear resistance, strong thermal and electrical conductivity, and low thermal expansion coefficient are all properties of tungsten-molybdenum and tungsten-molybdenum alloy. production of components and the use of heavy materials in the aerospace and defense sectors. The current product is mainly used on the energized electrode of the argon arc welding machine.

3. Principle of Tungsten Molybdenum Alloy Energized Electrodes For TIG Welding Machine:
Tungsten-molybdenum alloy electrode argon arc welding is a welding method that uses a tungsten-molybdenum alloy rod as an electrode and argon gas for protection. The method composition is shown in the following figure. During welding, argon gas is continuously sprayed from the nozzle of the welding torch, and a protective layer is formed around the arc to isolate the air to prevent it from oxidizing the tungsten-molybdenum alloy electrode, the molten pool and the adjacent heat-affected zone, so as to obtain a high-quality weld. In the welding process, filler wire can be added or not added according to the specific requirements of the workpiece.


4. Features of Tungsten Molybdenum Alloy Energized Electrodes For TIG Welding Machine:


This welding method has the following advantages and disadvantages because the arc is burned in argon:


1) Argon has an excellent protective effect and can effectively isolate the surrounding air; it neither reacts chemically with metal nor dissolves in metal, making the metallurgical reaction in the welding process simple and easy to control, thus obtaining high-quality Welds provide good condition.


2) The electrode arc of tungsten-molybdenum alloy is very stable, and it can still burn stably even in the case of a small current (<10A), especially suitable for thin plate material welding.


3) The heat source and filler wire can be controlled separately, so the heat input is easy to adjust, so this welding method can be welded in all directions, and it is also an ideal method to realize single-sided welding and double-sided forming.


4) Since the filler wire does not pass current, there is no splash, and the welding seam is beautiful.


5) AC argon arc welding can automatically remove the oxide film on the surface of the weldment during the welding process. Therefore, some non-ferrous metals with strong chemical activity, such as aluminum, magnesium and alloys, can be successfully welded.


6) The tungsten-molybdenum alloy electrode has poor current-carrying capacity. Excessive current will cause the tungsten electrode to melt and evaporate, and its particles may enter the molten pool and cause tungsten inclusion. Therefore, the deposition rate is small, the penetration depth is shallow, and the productivity is low.


7) The use of argon gas is more expensive, the deposition rate is low, and the argon arc welding machine is more complicated. Compared with other welding methods (such as electrode arc welding, submerged arc welding, and CO2&shy; gas shielded welding), the production cost is higher.


8) The surrounding of the argon arc is greatly affected by the airflow, and it is not easy to work outdoors.
