Zirconiated tungsten electrode
The tungsten-tungsten electrode is an electrode variety developed in order to improve the defect that the pure tungsten electrode can easily melt and pollute the workpiece under high-load welding conditions, the electrode is characterized in that the end part of the electrode can be kept in a spherical shape to reduce the tungsten-permeability phenomenon under the condition of high load current, And has good corrosion resistance. The tungsten-tungsten electrode contains a small amount of nitrous oxide (ZrO2). The welding characteristics of the tungsten-tungsten electrode are generally between the pure tungsten electrode and the tungsten-tungsten electrode. In the AC welding, the tungsten electrode is the most common electrode, because it is easier to start the arc than the pure tungsten in the welding process, and the arc beam is stable, and the pollution can be well controlled, the current carrying capacity is good, and the tungsten electrode is the best non-radioactive tungsten electrode from the point of view of the performance. As with the tungsten electrode and the pure tungsten electrode, the welding work can only be carried out in an alternating current environment. The welding performance of the tungsten electrode is good in the alternating current environment. Especially in the case of high load current, the advantage of the tungsten electrode is that the other electrodes are not replaceable. At the time of welding, the end part of the tungsten electrode can be kept in a spherical shape to reduce the tungsten and tungsten, and has good corrosion resistance. Due to the presence of other alternative products, the demand for tungsten-fired electrodes will be reduced. The main alternative product is a tungsten electrode. The tungsten-tungsten electrode is also used for high-quality welding of the ray. A minimum of tungsten contamination is required for optimal applications. The tungsten-tungsten electrode is generally used for alternating current and is not recommended for direct current. The tungsten-tungsten electrode is used for the alternating-current welding of the magnesium aluminum and the alloy thereof. The welding of the tungsten-tungsten electrode can be located between the pure tungsten electrode and the tungsten-tungsten electrode, and is a tungsten electrode product developed in order to improve the defect that the pure tungsten electrode can easily melt and pollute the workpiece under high-load welding conditions.
