Pure tungsten electrode is the earliest electrode that applied for argon arc welding, and it is only used as a welding electrode or a resistance welding electrode under AC conditions as this type of electrode is prone to appear the phenomenon of no arc or pilot arc instability under DC welding conditions. This problem can be greatly approved by adding rare earth oxides. Generally, the tip of pure tungsten electrode is spherical, and is used in the process of sine…
Tungsten electrode is referred to as an electrode made of tungsten. It can be classified in accordance with the color of the electrode tip. There are a variety of tungsten electrodes. Tungsten electrode is divided into various types such as pure tungsten electrode, thoriated tungsten electrode, cerium tungsten electrode, composite tungsten electrode, lanthanated tungsten electrode, and silver tungsten electrode, etc. It depends on whether rare earth additive is added or not. Some types of tungsten electrode are shown as follows:…
98% sodium tungstate dihydrate may be studied by TG-DTG technology to know its dehydration process.
