Cerium Tungsten Electrode Characteristics And Packaging Requirements

Cerium Tungsten Electrode Characteristics

Cerium tungsten electrodes in the early 1980s, introduced to the United States , as a non- radioactive tungsten electrodes to replace thoriated tungsten . Cerium tungsten electrodes which usually contains 2% cerium oxide. Known cerium tungsten electrodes at a low voltage , for DC welding , because the low voltage arc easily in the job to be lower than 10% thoriated tungsten . For pipe welding , cerium tungsten electrodes are the most popular , also commonly used to weld small parts. And compared to pure tungsten electrodes , cerium tungsten electrodes have a lower rate of combustion or evaporation rate . With increasing the content of cerium oxide , these advantages are increased. Ce has the highest mobility , and thus the time at the beginning of welding , the welding performance is very good . Over time , the grain growth , the migration rate will be significantly reduced. However, at low voltages , a longer life than the thoriated tungsten electrode . Because of these characteristics, tend to favor short-cycle welding or soldering specific amount before you replace the electrode . High current, voltage tungsten electrode welding is best to use thorium or lanthanum tungsten electrode . Cerium tungsten electrodes (EWCe-2) successfully used for DC or AC on , but mainly for DC welding, because the AC welding, easy to split .

Cerium tungsten electrodes packaging requirements : 10 / plastic box , the length is 150mm or 175mm, 1000只per carton .
