ELECTRODE FOR CONTACT AND SEAM WELDING Russian patent published in 2009 - IPC B23K11/30 

Abstract RU 2355534 C2

FIELD: welding works.

SUBSTANCE: base of the proposed electrode is made from high electro- and heat-conductive material. The working surface of the electrode is strengthened with a layer of high-strength, heat-resistant material. On top of the surface of the electrode, there is copper foil, closed with the base of the electrode and fastened on it using rings, fitted using bolts and nuts. The working surface of the electrode has high electro- and heat-conductivity. During its operation, only the foil wears out, which can be easily replaced with a new one.

EFFECT: invention can be used in restoring worn-out parts.
