DEVICE FOR COOLING ELECTRODE-CAP OF CONTACT POINT WELDING (CPW) Russian patent published in 2017 - IPC B23K11/10 B23K11/30 

FIELD: electricity.

SUBSTANCE: holder is made with a conical lateral surface in the front part and has transverse windows in its rear part. In the axial cavity of the holder, a tube is installed for supplying refrigerant. The electrode-cap attached to the holder has a cavity with a cylindrical and conical surfaces. The conical surface of the cap is located on the conical surface of the holder. In the cavity formed in the front part of the holder, a sleeve is installed that has an end portion and a shank connected to the holder by a threaded connection. In the end part of the bushing, the transverse windows are formed, which are open to the annular cavity formed by the lateral surface of the sleeve and the cylindrical surface of the electrode-cap cavity, passing into its axial cavity. The front end of the refrigerant supply tube is integrally connected to the end portion of the sleeve, and the lateral clearance of the said tube is sealed at its rear end.

EFFECT: reducing the length of the holder, has high reliability and durability.
