elettrodi toriati Explanation: Da Wikipedia - Gli elettrodi, dovendo essere di un materiale capace di resistere alle temperature dell'arco elettrico, sono, ormai da molti anni solo in tungsteno o sue leghe, ai primordi di questa tecnologia (anni quaranta) venivano usati anche elettrodi di grafite. Il tungsteno, oltre ad avere caratteristiche termiche meccaniche migliori, è preferito per il suo elevato potere termoelettrico (capacità di emettere elettroni ad elevata temperatura), che stabilizza l'arco. Per aumentare il potere termoelettrico del W [Wolfram = tungsteno], talvolta gli elettrodi sono legati con piccole percentuali (1-2%) di Th [Thorium] (elettrodi toriati).
