Abstract:This paper summarizes the production of the platinum electrode of tantalum clad silver. Ta(Ag). It clarifies the determination of the design parameters for the composite electrode, the technological process, the tensile test of the composite Ta(Ag) wire, the spotwelding of the electrode seal. the examination for leakage of the electrode. the prcess for winding the platinum foil and spotwelding, and the process parameter for obtaining high-quality electrodes during the production of 1,000 and more electrodes. The electrode produced satisfied the needs of the engineering design. It was demonstrated that the electrode had a long life-span and property stability, and fulfilled the norms for saving electricity and increasing production.

 

Key words: platinum electrode Ta(Ag) leakage platinum winding and spot-welding
