Rare earth doped tungsten pins refer to tungsten needle electrodes that are doped with rare earth elements to improve the welding performance of pure tungsten electrodes and stimulate the electron work function.
This kind of t rare earth doped tungsten pin has the characteristics of high melting point, strong electron emission capability, high elastic modulus, and ablation resistance. It can be used in tungsten argon arc welding to improve arc starting, arc stability and welding quality. all play an important role.
The sharpened electrode is suitable for DCSP, that is, the tungsten needle electrode is connected to the negative pole of the power supply output, and the weldment is connected to the positive pole of the power supply. Also, its tip angle changes with application type, welding current, and electrode diameter.
