Product Description


Pure tungsten electrode is an early used electrode in argon arc welding, and it is also widely used in various specific welding industries. The pure tungsten electrode contains 99.5% less tungsten and no alloying elements. Pure tungsten electrode is only used as welding electrode under AC conditions or as resistance welding electrode. It can provide clean base metal surface, and the welding ball becomes sharp when heated. This shape provides a balanced waveform, and the AC welding arc is stable, which is particularly good. Pure tungsten has very high electron escape function, low steam pressure, low resistance, good conductivity, small thermal expansion and high elastic modulus. Therefore, the arc is stable at low current, and aluminum, magnesium and their alloys can be well welded when the current is lower than 5A. However, the emission electron requires a high voltage, and the no-load voltage of the welding machine is required to be high. The tungsten electrode burns obviously when working with high current for a long time. After the end is melted, it will fall into the molten pool, which will cause tungsten inclusion in the seam. Therefore, it is only used for welding some ferrous metals or welding unimportant parts.
