Title:
めっき鋼板の高周波抵抗溶接用の給電電極
Document Type and Number:
Japanese Patent JP6795881
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a power feeding electrode for high-frequency resistance welding of a plated steel sheet which prevents partial contact with the steel sheet, is capable of causing no poor appearance due to a spark at a welding time even when a high-anticorrosion plated steel sheet is used as material of welding H-shaped steel, and can be used continuously over a sufficient time period.SOLUTION: A power feeding electrode is formed into a spherical surface having a tip shape of a curvature radius of 10 to 30 m, by using chromium copper or alumina dispersion copper.SELECTED DRAWING: None
