Stable electrode design and method |
摘要 |
A method of making a unitized tungsten electrode which exhibits superior mechanical and electrical properties which includes providing a length of cylindrical cut stock having a predetermined diameter and length. The stock is ground to form a rough unfinished electrode having an enlarged tip or nose portion at one end integrally connected to an elongated shank section. The unfinished electrode is treated by exposure to a chemical etchant for a time sufficient to form a finished electrode characterized by a smooth nose and shank surface and rounded undercut and ends. The invention includes the electrode formed by the described process.
